IndianaJoe1216 Posted January 25, 2018 Share Posted January 25, 2018 Randomly the other day my parity drive just decided to go offline and is now marked as disabled and faulty in the UI. I ran the smart report from in the UI and there is no indication of any problem based on the results I am getting back. Is this just a data issue is there a procedure I should follow to recover or rebuild that drive? Quote Link to comment
JorgeB Posted January 25, 2018 Share Posted January 25, 2018 You need to resync parity, to do that you need to re-enable the drive: https://lime-technology.com/wiki/Troubleshooting#Re-enable_the_drive P.S. it might be a good idea to post your diagnostics anyway, even if the disk is fine there could be other visible issues, like cable problems or a known problematic controller, etc. 1 Quote Link to comment
IndianaJoe1216 Posted January 25, 2018 Author Share Posted January 25, 2018 Diagnostics attached. Thanks for the help! I will review that article. Unfortunately I am traveling and can't check for a cabling issue but it's in a hot swap sled so it would have had to come loose from the motherboard and the other connector is a locking connector so hopefully nothing fishy is happening. glados-diagnostics-20180125-1744.zip Quote Link to comment
JorgeB Posted January 26, 2018 Share Posted January 26, 2018 Everything looks fine, just resync parity, if you can I would still use a different hot swap bay (or swap with another disk) just to rule it out in case it happens again. Quote Link to comment
samtrois Posted February 1, 2018 Share Posted February 1, 2018 Going to hijack this thread as I have just had the exact same problem. I just got an email telling me my parity disk was in error state, now its marked with a red X, and I'm just trying to remain calm. Quick SMART check shows no issues. I booted into maintenance mode to do a filesystem check like @johnnie.black showed me for a previous issue, but this wasn't available for that disk(not sure if it's because of its parity or an error state). I also can not do a Parity-Check, only a Read-Check, which I think isn't including the parity disk. Am I correct in believing this can be caused in error, and I need to unmount and remount it and rebuild the parity drive? tower-diagnostics-20180201-1134.zip Quote Link to comment
JorgeB Posted February 1, 2018 Share Posted February 1, 2018 Disk looks fine, you need to re-enable the disk and resync parity, before doing that recommend swamping cables/backplane with a different disk to rule out cable issues if it happens again, then: http://lime-technology.com/wiki/Troubleshooting#Re-enable_the_drive 1 Quote Link to comment

byographic Posted February 2, 2018 Share Posted February 2, 2018 I think I have a similar problem, this night a scheduled parity check was interrupted because of a disk error. and now that disk is disabled. I have checked the smart status of that disk and everything pass. I have attached the diagnostic to inspect thanks by01-diagnostics-20180202-0935.zip Quote Link to comment
