    You also asked about the parity check / history - does that give us an idea if I could try popping in another disk and rebuilding from parity?  Or has parity been indeed rebuilt yesterday and I'm out of luck on that front?

    The emulated disk is being emulated from parity. What you see is what would be rebuilt on another disk.

     

    Normally when a disk is detected as new and set to be cleared, it shows up with a blue square, at least on current versions. You didn't mention that, which struck me as strange. Once a disk is cleared, data recovery from the physical disk is practically impossible. That's why I was hoping against hope that parity wasn't changed since the incident, as the clearing process is normally done to AVOID the need to update parity when adding a new disk.

     

    Before you throw in the towel I'd at least let the check run to completion.

    enterprise customers weren't shutting down their services every hour to run snapshots

    They are also not typically running software that chokes if the file wasn't closed during backup. Many consumer level software packages behave poorly if the recovered file is in a state that indicates it's currently in use.

    Also, disk check has been running on the emulated disk8

    Did you run the check from the GUI or at the command line? It's easy to get wrong at the command line.

     

    It is the emulated disk (red X instead of green dot) that you are checking, correct?

    Crucial question - how would I know if parity is still valid from before the disk dropped as opposed to anything done since having updated parity?

    When was your last parity check that completed with zero errors?

    Why is the 1st prereq to setting up a self hosted instance to get a login to their site?

     

    Is the self hosted still reliant on their service?

    Do you have backups of all the important data? Moving stuff around like this is one of the riskiest things you can do, it's all too easy to accidentally delete stuff.

     

    If not, I recommend NOT removing any of the old drives, instead be patient and add drives to Unraid as you have the resources, and make copies instead of moving.

    I see. Thanks, will attempt that next.  Although it was weird in first place upon booting up that the drive in question showed up in Unassigned Devices and Array didn't show as degraded. 🤨

    That makes me think something went terribly wrong. I hope you have good backups, sounds like parity may not be valid with that disk. Hopefully it's still valid from before the disk dropped.

    could I just try to rebuild this drive from parity since it hasn't yet been updated? Wouldn't that be one way of getting this data back?

    If you want to, you could physically disconnect that disk, then when Unraid is started it will show what is emulated by parity. Be aware that doing that will put you in a riskier spot, if one of your other disks fails you would be at a greater risk of losing both drives.

     

    Just be very very sure you remove the correct disk, and once you remove it, don't put it back in the system until the emulated disk slot has a repaired filesystem. That way if the emulated disk is also corrupt, you at least get another shot at fixing the filesystem on the physical disk.

    Will this just format the drive and start rebuilding its data from parity?

    It will update the parity drive to show that the drive is blank, overwriting the corrupt filesystem with a blank one, removing any data.

     

    What you are seeing is what is on the drive, a corrupt filesystem. You need to run a filesystem check in the GUI for that drive.

     

    The drive is not disabled, it doesn't have a red X.
