description |
[Impact]
* Ubuntu enables automatic TRIM / DISCARD on all filesystems that support it, such that on SSD-like storage devices the performance over time is improved. ZFS, as setup by ubiquity, did not used to enable autotrim option. But it should have it enabled.
[Test Case]
* Complete install using zfs
* Check that the zfs pools have autotrim feature enabled
[Regression Potential]
* When autotrim is in progress, i/o performance may be observed as stalling. However, periodic trim outweighs the benefits. Advanced operators may choose to disable autotrim, and execute it manually during regularly scheduled maintenance windows.
[Other Info]
* Shipped in groovy already |

1. Complete install using zfs
2. Reboot and login
3. Check that the zfs pools have autotrim feature enabled with the following command:
$ zpool get autotrim
Both pools must have the autotrim property set to 'on'.

bpool autotrim on local
rpool autotrim on local

You can also check the status of trimming with:
# zpool status -t rpool
pool: rpool
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
nvme0n1p4 ONLINE 0 0 0 (100% trimmed, completed at mer. 03 juin 2020 07:50:22)
