Hello everyone,
After migrating 4 drives containing two single discs and one RAID0 group containing 2 discs from qnap NAS TS431 to new NAS TS431K everything went okay, all discs and RAID0 group showed in new NAS, but after a few days it unmounted, and now shows as RAID group 2 Unmounted.
And I can not mount it back. All discs are healthy.
I have a basic knowledge of mdadm. But don't know exact commands to get more info on this problem.
Any tips are welcome.
HELP needed! RAID group unmounted.

Yes, backup is not an issue. I just wanted to know why would this happened and if I can safely mount it back without using a back up.
