Great!! Thanks to ryecoaaron and br41n. You did it! E was the system drive!
The RAID 5 is working again and as it seems right now, i lost no data!

I thank you both very much!

greets John

mdadm --assemble /dev/md127 /dev/sd[acdef] --verbose --force

Gave me this output:

mdadm: looking for devices for /dev/md127
mdadm: no RAID superblock on /dev/sde
mdadm: /dev/sde has no superblock - assembly aborted

Thanx in advance Ryecoaaron

Disk /dev/sdf doesn't contain a valid partition table

Hello out there,

Running OMV 2.1.6. My Raid5 is gone. First i had a raid clean/degraded message by e-mail. that was about /dev/sdg that was faulty.
So i wanted to replace this disk with a new one. I had at first the next devices /dev/sda, /dev/sdc, /dev/sdd, /dev/sde, /dev/sdf and /dev/sdg together forming md127

Now devicenames are mixed up /dev/sda is ok but then /dev/sdc is now /dev/sdb! and so on for the next devices?!
I didn't replace a disk jet!

Via cat /proc/mdstat i see i have 2 personalities?

"root@OMV:~# cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md126 : inactive sda[3](S)
1953383512 blocks super 1.2

md127 : inactive sdb[0] sdd[2] sdc[1]
2929894536 blocks super 1.2

unused devices: <none>"
So i want to get them all in md127 and names as /dev/sda, /dev/sdc, /dev/sdd, /dev/sde, /dev/sdf to rebuild my raid.
Can i somehow rename /dev/sdc to /dev/sdd and so on in reverse order to get my devicenames the same as it was?

In GUI i cab see in storage my dics but in raid management there's nothing.
I hope i can somehow rebuild or rescue my raid with your help?

Thanx in advance.

John
