Perfect! I had to use xfs_repair -L to trash the log file but it came back quickly. Most file and folders are still intact. There are some in lost and found but the sub folder and file names look intact. Not sure if I will keep those or restore them from backup instead. sdn was a potential new drive that failed preclear. It's getting RMAd, I pulled it out. tower-diagnostics-20250603-0915.zip

Everything went smoothly from the GUI. Here is the new Diagnostic. tower-diagnostics-20250602-2057.zip

Ok. I have cloned drive 5. No read errors at all. When adding the new cloned drive in it's place, the array shows it as new though and wont start the array to allow a rebuild. Is there a way for me to set it as the existing drive and not new?

Makes sense. Drive 5 mounts fine on a linux VM and the data looks intact for now. Is the only way to force #5 back into the array to rebuild #8 with it is to do the ddrescue clone to a new disk and then update the config with the new drive?

I'm not totally sure, I hadn't got around to fixing my email notifications. Everything was good 2-3 weeks ago when I was in there. I was extremely low on free space but that's all I noticed. I'm assuming that drive 5 dropped out first because it is showing as emulated but I suppose its possible that they were both affected by the same power failure. If they happened at different times, It's possible some things were written to the array in between but I had those older drives excluded from the most used shares so it's also possible that there was not.

Hello, Looking for some guidance on the best process to recover. 24 Bay Enclosure, 16 total disks, single parity, using the Supermicro X9DR3-F. I had a single disk (disk 5) drop out as invalid and was emulated but the drive passes SMART test. I only see a few pending sectors for it . After a power failure I lost another drive entirely and isn't detected on any system. (Disk 8). Data on either of the drives is not critical but would preferable to not lose it. Ideal scenario, I force drive 5 back into the array and emulate Disk 8 for a rebuild. Second best would be to recover the array with whatever data is currently on all of the drives aside from the failed #8. Worst case scenario, Neither 5 or 8 have anything irreplaceable and I would just rebuild the array without those 2 drives. I have 2 new parity drives on order to upgrade the size and replace the single parity. For options 2 and 3 I would do the rebuild in a few days and add/replace the parity disks at the same time, in case that changes the advice. Diagnostics are attached.
