description |
autotrim should be enable and people upgrading should have trim enabled to prevent performance degration on SSD over time |
[Impact]
* Autotrim (a fresh feature in 0.8) hasn’t been enabled on purpose on new ZFS installation.
* Now that we personnaly ran it on our SSD for some weeks, we have been able to experiement it and test its robustness (empirically)
* We need to enable it so that users with SSD don’t suffer from performance degration over time, as in traditional ubuntu which has trim supported.
[Test Case]
1. zpool status -t <pool> -> the pool was never trim.
2. zpool get autotrim <pool> -> should be off
3. Install ZSys update
4. zpool status -t <pool> -> trimming is done or in progress.
5. zpool get autotrim <pool> -> should be on
[Regression Potential]
* The upgrade set autotrim on both rpool and bpool (and only on them) to not impact other pools.
* As autotrim is only for new write, we issue a manual zpool trim commands over them, which is ran in background by the kernel zfs module. The commands exits immediately.
* We also tested installations without bpool. |
