I'm using Open Media Vault 3 that is based on Debian 8.
I already have a RAID1 of 2x4TB WD Caviar Red, and now I'm tring to build a RAID1 with two Seagate Ironwolf 6TB.
Whe I build it anything is fine and I can create an ext4 partition on it and use it without a problem.
The problem is that every time that I reboot only the new RAID1 disappears. The old one is working just fine without any problem.
If I look with gparted both hard drives has no partion, like I never built a RAID1 with them, but if I look with testdisk I can find every file. Also if I try to rebuild the RAID the files will still be there, so I'm not losing my data.
After the reboot I tried to see if I could find md0 but this is the result:
mdadm --detail --scan ARRAY /dev/md127 metadata=1.2 name=NAS:Data UUID=ed696fd2:96feba4f:ab44fb72:b800fb01
No md0, only 127! I also tried with this command:
root@Delibird:~# mdadm -Es ARRAY /dev/md/Data metadata=1.2 UUID=ed696fd2:96feba4f:ab44fb72:b800fb01 name=NAS:Data
and still no result.
This is the conf file (/etc/mdadm/mdadm.conf)
# mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. # Note, if no DEVICE line is present, then "DEVICE partitions" is assumed. # To avoid the auto-assembly of RAID devices a pattern that CAN'T match is # used if no RAID devices are configured. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # definitions of existing MD arrays ARRAY /dev/md127 metadata=1.2 name=NAS:Data UUID=ed696fd2:96feba4f:ab44fb72:b800fb01 ARRAY /dev/md0 metadata=1.2 name=Delibird:Telefilm UUID=4de2d990:37fa60cf:b34e2c9e:63b4d0ca
I tried to update the conf for the boot with
But even after that, the RAID1 is still missing after the reboot :(
I finally tried wit this command:
mdadm --assemble --scan
but it did nothing
How should I do? I really don't know how to solve my problem!
