November 30, 20241 yr I recently migrated all my drives to a Supermicro 4U and moves all my SSDs to be connected via the backplane to a LSI. (All SSDs used in a Pool.) And later I become aware that SSDs TRIM sometimes don't work well with certain LSIs on certain softwares, and sometimes it would stop working due to software (Unraid) upgrades. So my question is, if I want to know for sure that TRIM is working correctly for a given drive at any given time, what would be the best way to check it? say the drive is sdi 1. run hdparm -I /dev/sdi on it? (likely no but I don't know for sure) 2. check the GUI somewhere? (probably no as I can't find anything in the drive's info page, but would be great to be able to) 3. run a fstrim -v /mnt/name_of_pool_using_ssd? (probably this but I don't know for sure) Thanks!
