tim8v Posted September 26, 2022 Share Posted September 26, 2022 hi, tried a few things to sort this issue out but going round in circles. Brief story, I had 4 x 250Gb WD SSD drives in a BTRFS cache pool. I was running out of free space so I decided to upgrade them to Crucial MX500 1Tb x 4. I replaced the first 250Gb with a 1Tb and all was ok and ran like that for a week with no issues. I have now replaced another but I am getting the drives now appearing in Unassigned devices. I have tried maintenance mode and run a check, no issues, tried removing from UD but they come back. I get a message saying one of the 1Tb drives I is missing from the pool. I can browse to most of the shares on the cache except the /mnt/user/system (says too many files). The only thing I can think of is I did something wrong when reassigning the cache drives before I mounted the array. Any help would be appreciated. Quote Link to comment

JorgeB Posted September 26, 2022 Share Posted September 26, 2022 Problem with the HBA, then it dropped all the devices, I would recommend using the onboard SATA for the SSDs anyway, or trim won't work. Quote Link to comment
tim8v Posted September 27, 2022 Author Share Posted September 27, 2022 ok, seems to be ok now, reseated HBA and rebooted. Regarding the HBA and TRIM, I was under the impression that this card did support TRIM. The WD Greens will be gone by today and replaced with a couple more MX500 1Tb's Quote Link to comment

Not with that firmware, some older releases did, though only for SSDs with determinist read zeros after trim support. Quote Link to comment
tim8v Posted September 27, 2022 Author Share Posted September 27, 2022 Ok, is there a list of HBAs that do have TRIM support for SSD's? Quote Link to comment
JorgeB Posted September 27, 2022 Share Posted September 27, 2022 All models listed below except the LSI HBAs: 1 Quote Link to comment
tim8v Posted September 27, 2022 Author Share Posted September 27, 2022 thanks, very useful. so just to be clear a ASM1164 based card would be fine with SSD's connected for a cache pool? Quote Link to comment
