September 26, 20205 yr Hiya! A few days ago I noticed I couldn’t use my shares. Checked Unraid and my one disk has Unmountable: no filesystem I followed part of SpaceinvaderOne’s video and ran xfs_repair with -nv and got this: Phase 1 - find and verify superblock... superblock read failed, offset 0, size 524288, ag 0, rval -1 fatal error -- Input/output error I am running Unraid 6.8.3 on a R5 2600. The drive in question is a 2TB Seagate Compute (only drive in the array). I don’t have any parody drives (a big mistake, I’ve been planning on getting one for the longest time). Server was built in April, been up for 25 days without errors.
September 26, 20205 yr Author Here you are. I’m off to bed now as it is 0002 here, but I will happily respond to and appreciate any help in the morning. Thanks! elrond-diagnostics-20200926-0001.zip
September 26, 20205 yr Community Expert Disk1 dropped offline, power down, check cables and post new diags.
September 26, 20205 yr Author I replugged the cables, booted it up, and got a message saying "Sector ct8 reallocated" or something similar. Drive appears to be working, should I boot up out of maintenance mode and see, or is there something else I should do? Thank you so much! elrond-diagnostics-20200926-0934.zip Edited September 26, 20205 yr by boeingboi Uploaded diagnostics
September 27, 20205 yr Community Expert Start the array normally, disk will likely mount, if it doesn't run xfs_repair. 16 hours ago, boeingboi said: and got a message saying "Sector ct8 reallocated" or something similar Never a good sign, make sure you have anything important backed up, especially since there's no parity, you can also run an extended SMART test to confirm disk is still OK.
September 27, 20205 yr Author Started it normally, was able to move images at an appropriate speed. SMART test ran fine, I will be buying a parity disk as soon as possible now that this has happened. Thanks!
