TheScrantonStrangler Posted July 8, 2019 Share Posted July 8, 2019 Hi all, I recently purchased a 12(+2) bay Dell r510 and dropped in a H200 LSI 9211-8i without doing proper research on whether or not it would work for my use case. Apparently that particular card doesn't support TRIM on most SSD's aside from a very select few. Luckily for me, the Crucial bx500 SSD I have as my cache drive supports it. Linux 4.19.56-Unraid. root@Tower:~# hdparm -I /dev/sdf | grep TRIM # Crucial bx500 used as cache drive * Data Set Management TRIM supported (limit 8 blocks) * Deterministic read ZEROs after TRIM root@Tower:~# hdparm -I /dev/sde | grep TRIM # Samsung 850 unassigned drive * Data Set Management TRIM supported (limit 8 blocks) root@Tower:~# fstrim -h Unfortunately, when I run fstrim -v /mnt/cache/, I get this relatively cryptic error. root@Tower:~# fstrim -v /mnt/cache/ fstrim: /mnt/cache/: FITRIM ioctl failed: Remote I/O error Is there anything to be done to get TRIM working on my system? Anybody else with an r510 have any suggestions on what I should do? I am still within the return window for the LSI 9211-8i but would rather not have to return it as it took the card about 3 weeks to arrive to me from the US. tower-diagnostics-20190708-1830.zip Quote Link to comment
JorgeB Posted July 9, 2019 Share Posted July 9, 2019 Trim on LSI SAS2008/2308 hasn't been working for a while, it appears to be a kernel/driver issue, it works on the newer LSI SAS3008 based controllers, or use onboard SATA if possible. Quote Link to comment
