a hard drive disk needed to be changed.
Afterwards I recovered my raid 5 and everything is fine, but in the raid overview there is listet another raid.
/dev/md0 consists of the three hard drive disks, which are still in the raid5.
But I don´t know what the Mirror raid is mirrowing.
Also I can´t recover it.
Can anyone explain what this is and what to do with it.
Thanks a lot.
