Need to Access RAID1 HDD via mdadm

Post by gcok » 21 May 2022, 21:04

long story short

problem
I can no longer access TNAS (stuck on initialzation)

The device needs its drives reformatted from BTRFS to EXT4

relucatntly tried remote support but it did not happen....

I have am now trying to fix myself by accessing RAID drive on a spare pc using linux

tried

mdadm -D /dev/md125
lists RAID info

attempting to mount

I get mount:unknown filesystem type 'LVM2_manager

has anybody successfully gained access to their TNAS drives via mdadm

as I side note I do have a windows machine if its possible to and/or easier to use that if its possible at all ?

objective

I need to gain access to the files on either of the RAID drives so they can be backed up to 3rd drive and TNAS can be setup again

You could check out https://help.ubuntu.com/community/Insta ... rch=Titles. Most ways I've seen involve installing the OS, setting up the raid array, then migrating the OS over onto it.
