April 5, 20224 yr I've been upgrading my server with some new disks. One even failed so I'm replacing that now. But instead of the normal 120-150 MBs I get when it starts I'm getting 1-10MBs. I have stopped Docker and the VM manager. I rebooted and that didn't fix anything either. Attached is my diagnostics. blue-diagnostics-20220405-1114.zip
April 5, 20224 yr Community Expert Then parity could be failing, but doesn't look like it is, try a different SATA port or swap with another disk and post new diags.
April 5, 20224 yr Author Okay, I'll try that next. I was going to run hdparm -tT /dev hdparm -tT /dev on each disk to see if one is reading slowly as well.
April 5, 20224 yr Author All the disks came back with strong cache and regular read speeds from hdparm. Here is the updated diags. blue-diagnostics-20220405-1215.zip
April 5, 20224 yr Community Expert It's still in the same port. 20 minutes ago, JorgeB said: try a different SATA port or swap with another disk and post new diags.
April 5, 20224 yr Author Which one is in the same port. I changed the new disks port. Many of the drives are in an HBA with a SAS to Sata so I can't really change many ports.
April 5, 20224 yr Community Expert Parity is the one having issues, swap ports with another disk, there are 7 other disks using the same controller.
April 5, 20224 yr Author I think that fixed it. I'm getting a range of speeds from 25MBs to 160MBs. Diags attached. So is the port on the mobo bad then? blue-diagnostics-20220405-1258.zip
April 5, 20224 yr Community Expert There are still issues, possibly less then before but they are still there, and they fallowed the disk, so it's not the port, still looks like a cable problem to me, power or SATA, but if you really swapped them it could be the disk.
April 5, 20224 yr Author Okay, I can look into replacing the disk. I'm getting a much more consistent 145MBs now. Are some cables recommended over others?
