I cut the power to the server on accident.  When it restarted all the disk shows as unassigned.  How would I fix this?  I have attached the diagonostics and syslog.  I'm using unraid 6.1.5.  Thanks for any help.

Do you know which disk is parity? Did you have single or dual parity?

Yeah, doh!

 

You can either assign all disks as data disks, there should only be one unmountable disk, if so that's parity, then do a new config assign all disks, check parity is already valid and run a correcting parity check, or to do it in a safer way and keep parity 100% in sync mount each disk read only from the CLI:

 

First create a mount point, e.g.:

mkdir /temp

then mount a disk read only:

mount -o ro /dev/sdX1 /temp

Replace X with the correct letter, note the 1 after the device, i.e., sdc1, if it doesn't mount it's parity, if it does it's a data disk, unmount the disk with:

umount /temp

and repeat for the others.

 

If there's only one unmountable disk it's parity, assign it to the parity slot and the remaining disks as data disks, order doen't matter with single parity, before starting the array check "parity is already valid" and start the array.

 

 

Forgot to mention, when done make sure you upgrade Unraid, what happened to you is known bug with v6.1.x releases, fixed a very long time ago.

 

 

 

 

Will look into upgrading.  Everything is up and running again.  Thanks a lot.

You really must do this upgrade. Nobody is supporting the version you have and most plugins will be incompatible.
