JorgeB Posted September 27, 2021 Share Posted September 27, 2021 There are constant ATA errors on disks 1 and 3, check replace cables on both, there's also data corruption being detected on disk1, run memtest. Quote Link to comment
BigDaddyMoe Posted September 28, 2021 Author Share Posted September 28, 2021 replaced the cables, now I recieve "Unmountable disk present" for disk 1 tower45tb-syslog-20210928-1423.zip tower45tb-diagnostics-20210928-0923.zip Quote Link to comment
JorgeB Posted September 28, 2021 Share Posted September 28, 2021 There were some writes missing to disk1, likely due to the cable issues, you can try btrfs restore (option #2) to recover the data, disk will need to be formatted after, this error is fatal, and if you haven't yet you should first run memtest like mentioned above.

BigDaddyMoe Posted September 28, 2021 Author Share Posted September 28, 2021 Thanks not sure how to run memtest. Do I boot up on the non GUI to run? Quote Link to comment
JorgeB Posted September 28, 2021 Share Posted September 28, 2021 It's the last option on the Unraid boot menu, it doesn't work if booting UEFI, only CSM. Quote Link to comment
BigDaddyMoe Posted September 28, 2021 Author Share Posted September 28, 2021 I see option 2 is not GUI either. Kinda out of my abilities as a newbie. Shouldnt my parity disk be able to rebuild my disk 1? Quote Link to comment
BigDaddyMoe Posted September 28, 2021 Author Share Posted September 28, 2021 Prior I could read my data on Disk 1, but not write to it. Now I can 't access it to copy it or backup. Any suggestions that are in the GUI interface for a newbie? Quote Link to comment
BigDaddyMoe Posted September 28, 2021 Author Share Posted September 28, 2021 Anyway I can get back to previous position of just read only on Disk 1 so that I can back up files? Quote Link to comment
BigDaddyMoe Posted September 28, 2021 Author Share Posted September 28, 2021 so "Format will create a file system in all Unmountable disks." will not bring back my files on disk 1 from the parity disk? I thought UNRAID could lose one disk and it could recover. What am i missing? Quote Link to comment

The problem is not a lost disk, but file system corruption. the general case for handling this is described here in the online documentation accessible via the Manual link at the bottom of the Unraid GUI.

BigDaddyMoe Posted September 28, 2021 Author Share Posted September 28, 2021 I do not have access to check filesystem status, scrub, or balance they ar all greyed out and say "See Disk Settings" after them. Anyway I can get back to read only so I can save the files? It is frustrating that I really dont have 1 disk loss recovery! tower45tb-diagnostics-20210928-1129.zip tower45tb-syslog-20210928-1628.zip Quote Link to comment
BigDaddyMoe Posted September 28, 2021 Author Share Posted September 28, 2021 What do I do if I DO NOT have access to "check filesystem status" ? Quote Link to comment

JorgeB Posted September 29, 2021 Share Posted September 29, 2021 Check filesystem is going to help here, best bet is using btrfs restore like I mentioned above, I think the instructions in the FAQ are fairly easy to follow even for users not familiar with the CLI, but feel free to ask here if you have any doubts.

BigDaddyMoe Posted October 1, 2021 Author Share Posted October 1, 2021 I am able to restore the files with "btrfs restore -vi /dev/sdi1 /mnt/disk7/restore" only problem all the historical dates of the files are changed to today Quote Link to comment
BigDaddyMoe Posted October 1, 2021 Author Share Posted October 1, 2021 (edited) I did not start in maintence mode, didn't think that worked for btrfs. "If the file system is BTRFS, then make sure the array is started, and NOT in Maintenance mode. Important note! Drives formatted with XFS or ReiserFS must be checked and repaired in Maintenance mode. Drives formatted with BTRFS cannot be checked or repaired in Maintenance mode! They must be checked and repaired with the array started in the regular mode."

BigDaddyMoe Posted October 1, 2021 Author Share Posted October 1, 2021 But mine is greyed out so? Quote Link to comment
JorgeB Posted October 1, 2021 Share Posted October 1, 2021 Like already mentioned check filesystem won't help for this case. Quote Link to comment

JorgeB Posted October 21, 2021 Share Posted October 21, 2021 As already mentioned only/best option for that problem is using btrfs restore. Quote Link to comment
