I'm currently going through a data rebuilt, where I expect the contents to be emulated but unraid seems to be misbehaving.

Disk 10 and Disk 11 are missing, I was expecting the emulated volumes to be mounted with my files from parity.

 

In syslog it looks like the emulated filesystem might be broken?

What happened was i had a loose cable so had to stop the rebuild and replug it in, when i rebooted the parity process started again from zero.

 

 

I have the original disks, but all the files from the emulated system seem to have gone.

 

Do i need to wait for a parity rebuild and then do some kind of repair?

Since you still have the originals, it's OK to do the repair after the rebuild so might as well let the rebuild complete. Of course, DON'T FORMAT.

Okay thanks, will wait for it to finish and stop radarr and sonarr so they don't redownload
