Twan_ Posted April 8, 2021 Author Share Posted April 8, 2021 do i need to restart the server or just the array? Quote Link to comment

I did remove a drive but the drive with so many writes is sdd not sdh, in the smart data sdh is a 500gb disk but that is a different disk than the sdh disk from the syslog from yesterday Quote Link to comment
trurl Posted April 8, 2021 Share Posted April 8, 2021 On mobile now so can't look at Diagnostics When a disk is dropped it will reconnect as a different device and not assigned Quote Link to comment
JorgeB Posted April 8, 2021 Share Posted April 8, 2021 You have multiple disk errors on the log, but the advice remains for disk1: 33 minutes ago, JorgeB said: Check/replace connections and post new diags after array start. Quote Link to comment
Twan_ Posted April 8, 2021 Author Share Posted April 8, 2021 i restarted and reseated the disk, everything seems to be working tower-diagnostics-20210408-1839.zip Quote Link to comment
JorgeB Posted April 8, 2021 Share Posted April 8, 2021 Disk1 is rebuilding but everything looks fine so far, you can also swap cables/slot with another disk just to rule that out if it happens again. Quote Link to comment
Twan_ Posted April 8, 2021 Author Share Posted April 8, 2021 i cant swap it out with another disk, because i only have an array of 1 disk and parity Quote Link to comment
JorgeB Posted April 8, 2021 Share Posted April 8, 2021 I meant in the server, use different cables or physical slot. Quote Link to comment
Twan_ Posted April 8, 2021 Author Share Posted April 8, 2021 i think a different cable or other hba would be best practice, because now my parity drive just got errors Quote Link to comment
JorgeB Posted April 8, 2021 Share Posted April 8, 2021 Yep, PSU could also be the problem. Quote Link to comment
tech_rkn Posted April 8, 2021 Share Posted April 8, 2021 HI, i had on a totaly different system a disk showing the same behaviors. i did fix the problem using a new sata cable. 7 months later, the same disk shown the same troubles, but this tiime it was a real failure due to vibrations. Could it be that your disk is a SMR hard drive as mine ( 4TO WD Red NAS WD40EFAX ) Quote Link to comment
Twan_ Posted April 8, 2021 Author Share Posted April 8, 2021 i know it is not a SMR drive, because it is a 600GB enterprise SAS 10k Disk Quote Link to comment
