One of the drives in my array has become corrupted and the entire array is shut down. It happened a while ago, but I haven't touched it until recently. I have run BTRFS Check but it stopped after "checking extents". I'm not sure what my next steps should be to attempt recovering this data. Thanks! zzunraid-diagnostics-20260615-2355.zip

Disk 1 in my array is showing as "Unmountable: wrong or no file system". Scrub does not appear to be permitted in since the drive doesn't get mounted. I've started the array in maintenance mode and then ran btrfs check file system parent transid verify failed on 956727296 wanted 211086 found 211078 parent transid verify failed on 956727296 wanted 211086 found 211078 parent transid verify failed on 956727296 wanted 211086 found 211078 Ignoring transid failure ERROR: child eb corrupted: parent bytenr=47579136 item=7 parent level=2 child bytenr=956727296 child level=0 ERROR: failed to read block groups: Input/output error ERROR: cannot open file system Opening filesystem to check... Possible causes... I've been attempting an install of a new HBA to add some new drives (finally go that to work today). During this operation, I had some power glitches and the system started/shutdown multiple times over ~15 minutes. I did not have my UPS hooked up at the time. :( What is the next step to recover this drive? zzunraid-diagnostics-20250727-1756.zip
