A year ago, the old motherboard on which unRAID sat stopped working. I did not do anything about it immediately as I wanted to weigh the options, and then procrastination took over. So I still have 8 WD Red 8TB disks sitting idle (two of them are parity), all formatted XFS. I also have two BTRFS-formated SSD cache drives.

 

Now I need to get the stored data back. Is it possible to mount all the devices (HDDs, SSDs and flash drive) in a totally different rig? Do I need to do something special to make the data accessible? Or is there a better way?

 

Thanks 

You should be able to connect all of the old drives up to a new MB with the original flash drive plugged and boot the system.  The server part should come up running.  Any VM's might be a bit more problematic.

 

IF you are the cautious type, you might want to edit the  /config/disk.cfg   file on your boot drive.  You want to find this line    startArray="yes"    and change it to   startArray="no".  This will prevent the array from autostarting until you can do a 'sanity check' in the disk assignments.  

Thanks. It’s what I hoped for. Now off to buy and build.
