Server froze, rebooted however can't boot due to mdadm failed

[dsh]

Helllo everyone.

I have Proxmox installed on top of Debian software RAID-10.

Today it froze and I restarted manually, unfortunately it doesn't boot due to mdadm error.

A. It gives following error on boot.



B. cat /proc/mdstat



C. blkid




What I find weird is boot error UUID doesn't match any UUID from blkid.

It's my first encountering this issue. Any help will be appreciated.

maybe you can boot on a live cd, and try to recover your raid.

There is initramfs, so everything is already there to recover. Scan for raid devices and assemble them, mount and fix it.
