aneelley Posted July 12, 2021 Share Posted July 12, 2021 I recently had a disk go bad so I replaced it. Took about 18 hours to rebuild from parity. During that rebuild, two disks showed read errors. I do not remember the disk numbers. I subsequently upgraded the OS and then rebooted and started a parity check. Now I am wondering if I shouldn't have went into each disk, ran a BTRFS scrub first and then ran a parity check? Just want to make sure I am doing things in the right order. Diags attached. unraid-diagnostics-20210712-1728.zip Quote Link to comment
aneelley Posted July 12, 2021 Author Share Posted July 12, 2021 PS - I *think* one of those disks that I saw read errors on was Disk17. Quote Link to comment
JorgeB Posted July 13, 2021 Share Posted July 13, 2021 You should have saved the diags before rebooting, you can run a scrub on the rebuilt disk to look for corruption and run an extended SMART test in all disks, or at least any disk where this is non 0 (like disk17): Elements in grown defect list: 8189 Quote Link to comment
aneelley Posted July 13, 2021 Author Share Posted July 13, 2021 Thanks. I will scrub all the disks and replace each as needed. Quote Link to comment
