Hi my fellow unraiders,

 

After switching two of my disks from xfs to btrfs and reformatted (now it's rebuilding), my server went limb - web GUI was working fine, but couldn't download diagnostics. I could ssh into the server but couldn't reboot. So I performed a hard reset and now at least 2 of my shares are missing. 

 

What should I do? Diagnostics attached.

I'm also missing about 8TB of data - roughly the data on the drives that got reformatted. 

 

I did do a parity check beforehand and it was fine... help...?

Did you change the format of disks that had data on them and then used the format option on them (which it sounds might be the case from your description).    If so you have erased the contents of those drives as you cannot change the format and keep their data intact.    The format option would have put up a dialog you had to acknowledge warning that proceeding would erase all data from the drive(s) being formatted.

 

if that is what happened, then all you can do is restore the data from your backups.
 

if something else happened then you need to give a more detailed description of the exact steps you took.   The diagnostics posted are from just after a reboot so we cannot see what happened earlier.

Thanks. I guess I'll just have to do some data recovery then.
