Continue using RAID 1 after change from original NAS Firmware to OMV Debian - mount gone after reboot

ManfredH83 · 12. Januar 2019

Hello,

I think I have a similar problem like in this Thread. I have converted from an original NAS Firmware (Zyxel NAS540) to OMV and very much love it. But there seems to be a problem with my backup storage (2 disk mounted in RAID1). Like in that other thread, the mount goes missing after every reboot. Possibly this could be corrected with the command, recommended in the other thread (mdadm --assemble --force --verbose /dev/md127 /dev/sd[bc]) however, I am not sure how to identfy the right parameters for my disk setup. Hopefully, you can help me identify the correct one?

General setup: 2 disks in JBOD (~3 TB) and 2 disks in RAID1 (~1 TB)
