# LVM Snapshots Collection
|
||||
|
||||
[](https://github.com/redhat-cop/infra.lvm_snapshots/actions) [](https://github.com/redhat-cop/infra.lvm_snapshots/actions) [](https://www.bestpractices.dev/projects/8141)
|
||||
|
||||
## Overview
|
||||
|
||||
A reliable snapshot/rollback capability is a key feature required to enable the success of RHEL In-place Upgrade automation solutions. Without it, users will be wary of using the solution because of the potential risk that their applications may not function properly after the OS upgrade. Including automation so that snapshot creation happens right before the OS upgrade reduces this risk. If there are any application issues uncovered after the OS upgrade, a rollback playbook can be executed to instantly revert the environment back to the original state as it was before the upgrade. Application teams will no longer have an excuse not to use in-place upgrades to bring their RHEL estate into compliance.
|
||||
|
||||
## Requirements
|
||||
|
||||
### Ansible Version
|
||||
|
||||
This collection requires ansible from version `2.14.0` and above
|
||||
|
||||
### Collections
|
||||
|
||||
This collection depends on the following collections
|
||||
|
||||
```yaml
|
||||
- "community.general": "*"
|
||||
```
|
||||
|
||||
## Roles
|
||||
|
||||
These are the roles included in the collection. Follow the links below to see the detailed documentation and example playbooks for each role.
|
||||
|
||||
- [`snapshot_create`](./roles/snapshot_create/) - controls the creation for a defined set of LVM snapshot volumes
|
||||
- [`snapshot_remove`](./roles/snapshot_remove/) - used to remove snapshots previously created using the `snapshot_create` role
|
||||
- [`snapshot_revert`](./roles/snapshot_revert/) - used to revert to snapshots previously created using the `snapshot_create` role
|
||||
- [`shrink_lv`](./roles/shrink_lv/) - controls decreasing logical volume size along with the filesystem
|
||||
- [`bigboot`](./roles/bigboot/) - controls increasing of the boot partition while moving, and shrinking if needed, the adjacent partition
|
||||
- [`initramfs`](./roles/initramfs/) - controls the atomic flow of building and using a temporary initramfs in a reboot and restoring the original one
|
||||
|
||||
## Installing the collection from Ansible Galaxy
|
||||
|
||||
Before using this collection, you need to install it with the Ansible Galaxy command-line tool:
|
||||
|
||||
```bash
|
||||
ansible-galaxy collection install infra.lvm_snapshots
|
||||
```
|
||||
|
||||
You can also include it in a `requirements.yml` file and install it with `ansible-galaxy collection install -r requirements.yml`, using the format:
|
||||
|
||||
```yaml
|
||||
---
|
||||
collections:
|
||||
- name: infra.lvm_snapshots
|
||||
```
|
||||
|
||||
Note that if you install the collection from Ansible Galaxy, it will not be upgraded automatically when you upgrade the `ansible` package. To upgrade the collection to the latest available version, run the following command:
|
||||
|
||||
```bash
|
||||
ansible-galaxy collection install infra.lvm_snapshots --upgrade
|
||||
```
|
||||
|
||||
You can also install a specific version of the collection, for example, if you need to downgrade when something is broken in the latest version (please report an issue in this repository). Use the following syntax to install version `1.0.0`:
|
||||
|
||||
```bash
|
||||
ansible-galaxy collection install infra.lvm_snapshots:==1.0.0
|
||||
```
|
||||
|
||||
See [Using Ansible collections](https://docs.ansible.com/ansible/devel/user_guide/collections_using.html) for more details.

# bigboot
|
||||
|
||||
The `bigboot` role is used to increase boot partition.
|
||||
|
||||
The role is designed to support the automation of RHEL in-place upgrades, but can also be used for other purposes.
|
||||
|
||||
## Contents
|
||||
|
||||
The role configures a dracut pre-mount hook that executes during a reboot to increase the size of the boot partition and filesystem. To make room for the boot size increase, the role first shrinks the size of the next partition after the boot partition. This next partition must contain either an LVM physical volume or a Btrfs filesystem volume. There must be sufficient free space in the LVM volume group or Btrfs filesystem to accommodate the reduced size.
|
||||
|
||||
> **WARNING!**
|
||||
>
|
||||
> All blocks of the partition above the boot partition are copied using `sfdisk` during the reboot and this can take several minutes or more depending on the size of that partition. The bigboot script periodically outputs progress messages to the system console to make it clear that the system is not in a "hung" state, but these progress messages may not be seen if `rhgb` or `quiet` kernel arguments are set. If the system is reset while the blocks are being copied, the partition will be irrcoverably corrupted. Do not assume the system is hung or force a reset during the bigboot reboot!
|
||||
|
||||
To learn more about how bigboot works, check out this [video](https://people.redhat.com/bmader/bigboot-demo.mp4).
|
||||
|
||||
## Role Variables
|
||||
|
||||
### `bigboot_partition_size` (String)
|
||||
|
||||
The variable `bigboot_partition_size` specifies the minimum required size of the boot partition. If the boot partition is already equal to or greater than the given size, the role will end gracefully making no changes. The value can be either in bytes or with optional single letter suffix (1024 bases) using [human_to_bytes](https://docs.ansible.com/ansible/latest/collections/ansible/builtin/human_to_bytes_filter.html) filter plugin.
|
||||
|
||||
### `bigboot_size` (String)
|
||||
|
||||
This variable is deprecated and will be removed in a future release. Use `bigboot_partition_size` instead.
|
||||
|
||||
The variable `bigboot_size` specifies by how much the size of the boot partition is to be increased. The value can be either in bytes or with optional single letter suffix (1024 bases) using [human_to_bytes](https://docs.ansible.com/ansible/latest/collections/ansible/builtin/human_to_bytes_filter.html) filter plugin.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The size increase may be slightly less than the specified value as the role will round down to the nearest multiple of the LVM volume group extent size or Btrfs sector size used for the next partition after the boot partition.
|
||||
|
||||
## Example playbook
|
||||
The following yaml demonstrates an example playbook that runs the role to increase the size of the target hosts boot partition to 1.5G:
|
||||
|
||||
```yaml
|
||||
- name: Extend boot partition playbook
|
||||
hosts: all
|
||||
vars:
|
||||
bigboot_partition_size: 1.5G
|
||||
roles:
|
||||
- bigboot
|
||||
```
|
||||
|
||||
# Validate execution
|
||||
The "Validate boot filesystem new size" task at the end of the run will indicate success or failure of the boot partition size increase. For example:
|
||||
|
||||
```
|
||||
TASK [bigboot : Validate boot filesystem new size] ****************************************
|
||||
ok: [fedora] => {
|
||||
"changed": false,
|
||||
"msg": "Boot filesystem size is now 1.44 GB (503.46 MB increase)"
|
||||
```
|
||||
|
||||
If the boot partition was already equal to or greater than the given size, the bigboot pre-mount hook configuration is skipped and the host will not reboot. In this case, the run will end with the "Validate increase requested" task indicating nothing happened. For example:
|
||||
|
||||
```
|
||||
TASK [bigboot : Validate increase requested] **********************************************
|
||||
ok: [fedora] => {
|
||||
"msg": "Nothing to do! Boot partition already equal to or greater than requested size."
|
||||
}
|
||||
```
|
||||
|
||||
During the reboot, the bigboot pre-mount hook logs progress messages to the console. After the reboot, `journalctl` can be used to review the log output. For example, a successful run will look similar to this:
|
||||
```bash
|
||||
# journalctl --boot --unit=dracut-pre-mount

# This is the new bigboot reboot script. Unlike the old script, this one

# The preparations to reduce the LVM physical volume or Btrfs filesystem

#

# 1. Move the end of the next partition to make it smaller

# initramfs
|
||||
|
||||
The `initramfs` role is included by the `shrink_lv` and `bigboot` roles to run an atomic flow of building and using a temporary initramfs in a reboot and restoring the original one.
|
||||
|
||||
The role is designed to be internal for this collection and support the automation of RHEL in-place upgrades, but can also be used for other purposes.
|
||||
|
||||
## Contents
|
||||
|
||||
To allow fast fail, the role provides a [`preflight.yml`](./tasks/preflight.yml) tasks file to be used at the start of the playbook.
|
||||
Please note that the [`main`](./tasks/main.yml) task file will not run the preflight checks
|
||||
|
||||
## Role Variables
|
||||
|
||||
All variables are optional
|
||||
|
||||
### `initramfs_add_modules`
|
||||
|
||||
`initramfs_add_modules` is a a space-separated list of dracut modules to be added to the default set of modules.
|
||||
See [`dracut`](https://man7.org/linux/man-pages/man8/dracut.8.html) `-a` parameter for details.
|
||||
|
||||
### `initramfs_backup_extension`
|
||||
|
||||
`initramfs_backup_extension` is the file extension for the backup initramfs file.
|
||||
|
||||
Defaults to `old`
|
||||
|
||||
### `initramfs_post_reboot_delay`
|
||||
|
||||
`initramfs_post_reboot_delay` sets the amount of Seconds to wait after the reboot command was successful before attempting to validate the system rebooted successfully.
|
||||
The value is used for [`post_reboot_delay`](https://docs.ansible.com/ansible/latest/collections/ansible/builtin/reboot_module.html#parameter-post_reboot_delay) parameter
|
||||
|
||||
Defaults to `30`
|
||||
|
||||
### `initramfs_reboot_timeout`
|
||||
|
||||
`initramfs_reboot_timeout` sets the maximum seconds to wait for machine to reboot and respond to a test command.
|
||||
The value is used for [`reboot_timeout`](https://docs.ansible.com/ansible/latest/collections/ansible/builtin/reboot_module.html#parameter-reboot_timeout) parameter
|
||||
|
||||
Defaults to `7200`
|
||||
|
||||
|
||||
## Example of a playbook to run the role
|
||||
The following yaml is an example of a playbook that runs the role against a group of hosts named `rhel` and increasing the size of its boot partition by 1G.
|
||||
The boot partition is automatically retrieved by the role by identifying the existing mounted partition to `/boot` and passing the information to the script using the `kernel_opts`.
|
||||
|
||||
```yaml
|
||||
- name: Extend boot partition playbook

# shrink_lv
|
||||
|
||||
The `shrink_lv` role is used to decrease the size of logical volumes and the file system within them.
|
||||
|
||||
The role is designed to support the automation of RHEL in-place upgrades, but can also be used for other purposes.
|
||||
|
||||
## Contents
|
||||
|
||||
The role contains the shell scripts to shrink the logical volume and file system, as well as the script wrapping it to run as part of the pre-mount step during the boot process.
|
||||
|
||||
## Role Variables
|
||||
|
||||
### `shrink_lv_devices`
|
||||
|
||||
The variable `shrink_lv_devices` is the list of logical volumes to shrink and the target size for those volumes.
|
||||
|
||||
#### `device`
|
||||
|
||||
The device that is mounted as listed under `/proc/mount`.
|
||||
If the same device has multiple paths, e.g. `/dev/vg/lv` and `/dev/mapper/vg/lv` pass the path that is mounted
|
||||
|
||||
#### `size`
|
||||
|
||||
The target size of the logical volume and filesystem after the role has completed.
|
||||
The value can be either in bytes or with optional single letter suffix (1024 bases).
|
||||
See `Unit options` type `iec` of [`numfmt`](https://man7.org/linux/man-pages/man1/numfmt.1.html)
|
||||
|
||||
## Example of a playbook to run the role
|
||||
|
||||
The following yaml is an example of a playbook that runs the role against all hosts to shrink the logical volume `lv` in volume group `vg` to 4G.
|
||||
|
||||
```yaml
|
||||
- name: Shrink Logical Volumes playbook
|
||||
hosts: all
|
||||
vars:
|
||||
shrink_lv_devices:
|
||||
- device: /dev/vg/lv
|
||||
size: 4G
|
||||
roles:
|
||||
- shrink_lv
|
||||
```
|
||||
|
||||
# Validate execution
|
||||
The script will add an entry to the kernel messages (`/dev/kmsg` or `/var/log/messages`) with success or failure.
|
||||
In case of failure, it may also include an error message retrieved from the execution of the script.
|
||||
|
||||
A successful execution will look similar to this:
|
||||
```bash
|
||||
[root@localhost ~]# cat /var/log/messages |grep Resizing -A 2 -B 2
|
||||
Oct 16 17:55:00 localhost /dev/mapper/rhel-root: 29715/2686976 files (0.2% non-contiguous), 534773/10743808 blocks

# snapshot_create role
|
||||
|
||||
|
||||
The `snapshot_create` role is used to control the creation for a defined set of LVM snapshot volumes.
|
||||
In addition, it can optionally save the Grub configuration and image files under /boot and configure settings to enable the LVM snapshot autoextend capability.
|
||||
The role will verify free space and should fail if there is not enough or if any snapshots already exist for the given `snapshot_create_set_name`.
|
||||
|
||||
The role is designed to support the automation of RHEL in-place upgrades, but can also be used to reduce the risk of more mundane system maintenance activities.
|
||||
|
||||
## Role Variables
|
||||
|
||||
### `snapshot_create_check_only`
|
||||
|
||||
When set to `true` the role will only verify there is enough free space for the specified snapshots and not create them.
|
||||
Default `false`
|
||||
|
||||
### `snapshot_create_set_name`
|
||||
|
||||
The variable `snapshot_create_set_name` is used to identify the list of volumes to be operated upon.
|
||||
The role will use the following naming convention when creating the snapshots:
|
||||
|
||||
`<Origin LV name>_<snapshot_create_set_name>`
|
||||
|
||||
### `snapshot_create_boot_backup`
|
||||
|
||||
Boolean to specify that the role should preserve the Grub configuration and image files under /boot required for booting the default kernel.
|
||||
The files are preserved in a compressed tar archive at `/root/boot-backup-<snapshot_create_set_name>.tgz`. Default is `false`.
|
||||
|
||||
> **Warning**
|
||||
>
|
||||
> When automating RHEL in-place upgrades, do not perform a Grub to Grub2 migration as part of your upgrade playbook. It will invalidate your boot backup and cause a subsequent `revert` action to fail. For example, if you are using the [`upgrade`](https://github.com/redhat-cop/infra.leapp/tree/main/roles/upgrade#readme) role from the [`infra.leapp`](https://github.com/redhat-cop/infra.leapp) collection, do not set `update_grub_to_grub_2` to `true`. Grub to Grub2 migration should only be performed after the `remove` action has been performed to delete the snapshots and boot backup.
|
||||
|
||||
### `snapshot_create_snapshot_autoextend_threshold`
|
||||
|
||||
Configure the given `snapshot_create_autoextend_threshold` setting in lvm.conf before creating snapshots.
|
||||
|
||||
### `snapshot_create_snapshot_autoextend_percent`
|
||||
|
||||
Configure the given `snapshot_create_snapshot_autoextend_percent` setting in lvm.conf before creating snapshots.
|
||||
|
||||
### `snapshot_create_volumes`
|
||||
|
||||
This is the list of logical volumes for which snapshots are to be created and the size requirements for those snapshots. The volumes list is only required when the role is run with the check or create action.
|
||||
|
||||
### `vg`
|
||||
|
||||
The volume group of the origin logical volume for which a snapshot will be created.
|
||||
|
||||
### `lv`
|
||||
|
||||
The origin logical volume for which a snapshot will be created.
|
||||
|
||||
### `size`
|
||||
|
||||
The size of the logical volume according to the definition of the
|
||||
[size](https://docs.ansible.com/ansible/latest/collections/community/general/lvol_module.html#parameter-size)
|
||||
parameter of the `community.general.lvol` module.
|
||||
|
||||
To create thin provisioned snapshot of a thin provisioned volume, omit the `size` parameter or set it to `0`
|
||||
|
||||
## Example Playbooks
|
||||
|
||||
Perform space check and fail of there will not be enough space for all the snapshots in the set.
|
||||
If there is sufficient space, proceed to create snapshots for the listed logical volumes.
|
||||
Each snapshot will be sized to 20% of the origin volume size.
|
||||
Snapshot autoextend settings are configured to enable free space in the volume group to be allocated to any snapshot that may exceed 70% usage in the future.
|
||||
Files under /boot will be preserved.

||||

||||

# snapshot_remove role
|
||||
|
||||
The `snapshot_remove` role is used to remove snapshots.
|
||||
In addition, it removes the Grub configuration and image files under /boot if it was previously backed up
|
||||
It is intended to be used along with the `snapshot_create` role.
|
||||
|
||||
The role is designed to support the automation of RHEL in-place upgrades, but can also be used to reduce the risk of more mundane system maintenance activities.
|
||||
|
||||
## Role Variables
|
||||
|
||||
### `snapshot_remove_set_name`
|
||||
|
||||
The variable `snapshot_remove_set_name` is used to identify the list of volumes to be operated upon.
|
||||
The role will use the following naming convention when reverting the snapshots:
|
||||
|
||||
`<Origin LV name>_<snapshot_remove_set_name>`
|
||||
|
||||
This naming convention will be used to identify the snapshots to be removed.
|
||||
|
||||
## Example Playbooks
|
||||
|
||||
### Commit
|
||||
|
||||
A commit playbook is used when users are comfortable the snapshots are not needed any longer.
|
||||
Each snapshot in the snapshot set is removed and the backed up image files from /boot are deleted.
|
||||
|
||||
```yaml
|
||||
- hosts: all
|
||||
roles:
|
||||
- name: snapshot_remove
|
||||
snapshot_remove_set_name: ripu

||||

# snapshot_revert role
|
||||
|
||||
|
||||
The `snapshot_revert` role is used to merge snapshots to origin and reboot (i.e., rollback).
|
||||
The role will verify that all snapshots in the set are still in active state before doing any merges.
|
||||
This is to prevent rolling back if any snapshots have become invalidated in which case the role should fail.
|
||||
In addition, it restores the Grub configuration and image files under /boot is it was previously backed up
|
||||
It is intended to be used along with the `snapshot_create` role.
|
||||
|
||||
The role is designed to support the automation of RHEL in-place upgrades, but can also be used to reduce the risk of more mundane system maintenance activities.

|

This naming convention will be used to identify the snapshots to be merged.
|
||||
|
||||
The `revert` action will verify that all snapshots in the set are still active state before doing any merges. This is to prevent rolling back if any snapshots have become invalidated in which case the `revert` action should fail.
|
||||
|
||||
## Example Playbooks
|
||||
|
||||
This playbook rolls back the host using the snapshots created using the `snapshot_create` role.
|
||||
After verifying that all snapshots are still valid, each logical volume in the snapshot set is merged.
|
||||
The image files under /boot will be restored and then the host will be rebooted.
