Recreate Raid 0 after reinstall?

Doc · 7. April 2015

Hi,I had a system running with 1 HD containing the OS and 4 other HDs in a stripe array (Raid 0, created using the Web GUI) for all my data. The hard drive containing OMV crashed and won't boot up anymore so I installed OMV on another hard drive.

What I want is to be able to get access to my Raid without losing any of the data. Is this possible?

Any help is appreciated, thanks! Please let me know whatever you need.

but strangely cat /proc/mdstat gives this:

Code

root@SERVER:~# cat /proc/mdstat
Personalities :
unused devices: <none>

Under /dev I can only only see /md and md127, so I tried assembling the md127 array...

Code

root@SERVER:~# cat /proc/mdstat
Personalities :
unused devices: <none>
root@SERVER:~# mdadm --assemble /dev/md127
mdadm: /dev/md127 not identified in config file.
root@SERVER:~# mdadm --assemble /dev/md127 /dev/sdc /dev/sdd /dev/sde /dev/sda
mdadm: failed to add /dev/sde to /dev/md127: Invalid argument
mdadm: failed to add /dev/sdc to /dev/md127: Invalid argument
