Public bug reported:
[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
** Affects: ubiquity (Ubuntu)
Importance: Undecided
Status: New
