English Applications

Hello
My mdadm (Raid 5) fails and I was not able to recover it.
I have an old version but was working fine with no issues
I have tried to recover it with mdadm --create --assume-clean with no success.
Now I’m getting
mdadm -D /dev/md0
mdadm: cannot open /dev/md0: No such file or directory

cat /proc/mdstat
Personalities : [linear]
unused devices: <none>

like de MDADM device doesn’t exist

VERSION
mdadm --version
mdadm - v3.0.3

If I do an mdadm --examine for each disk this is the output

cat raid.status

You choose OTHER VERSION as the prefix for the openSUSE version you use.

Of course we are then the more interested what version you use.

Also please:

There is an important, but not easy to find feature on the forums.

Please in the future use CODE tags around copied/pasted computer text in a post. It is the # button in the tool bar of the post editor. When applicable copy/paste complete, that is including the prompt, the command, the output and the next prompt.

An example is here: Using CODE tags Around your paste.
