Trying to recover a RAID1 (mirror) NAS drive
I'm new on this forum and to Linux so please accept my apologies if I am posting in the wrong thread.
My NAS electronics died (after 7 years).
I was informed (by a unverified web site) that my Thecus NAS uses the XFS file system and that, being RAID1, I should be able to access the data simply off one of the two mirrored drives on my Linux Mint system.
I installed XFS support and tried to mount the drive directly but was unsuccessful. Below is what I just tried...
All assistance will be greatly appreciated.
Thanks,

/dev/md10 looks like swapspace - not mounted
mount: you must specify the filesystem type
dell-mint ~ # mount /dev/md0 /media/nas-hdd
mount: unknown filesystem type 'LVM2_member'
