mathomas3 Posted June 10, 2022 Share Posted June 10, 2022 Hello, Having replaced a number of drives in the past, I have never really had issues with this, until today. I have a red balled SSD. I checked the SMART report and nothing was amiss but having another 512gb SSD (which I bought as a pair) I decided to just replace it. Shut down the system Replaced the SSD Powered up the array Took it offline Assigned the new disk Got an error message "The replacement disk must be as big or bigger than the original." I have looked around the forum some and I seen some mentions of using sg_format and sg_sanitize... all of these fail to run on this ssd. hdparm -N /dev/sdn reports max sectors = 1000215216/1000215216, HPA is disabled it's not an issue for me to go and get a 1tb drive to replace it with but it would be nice to use what I already have... Attached is the SMART report for the new ssd and for the tower itself Tks all for looking tower-smart-20220610-0925.zip tower-diagnostics-20220610-1126.zip Quote Link to comment
JorgeB Posted June 10, 2022 Share Posted June 10, 2022 Most likely explanation is that the SSD was first added to the array when Unraid used sector 64 for partition start, if you still have the old SSD intact, please post output of: fdisk -l /dev/sdX Replace X with correct letter.

trurl Posted June 10, 2022 Share Posted June 10, 2022 Do you know that SSDs in the array cannot be trimmed, and can only be written at parity speed? Quote Link to comment
mathomas3 Posted June 11, 2022 Author Share Posted June 11, 2022 I ended up getting a 1tb ssd to replace the 512... but I have a few machine around that I can plug this ssd into and run the report on... Quote Link to comment
mathomas3 Posted June 11, 2022 Author Share Posted June 11, 2022 Ill report back once that's done Quote Link to comment
