My setup can be seen in my signature. I use my data disks in that way that dev/sdb contains our stuff and dev/sdc is used as a backup drive (rsyncing sdb to sdc every night - this was a suggestion by ryecoaaron when I had problems keeping a RAID1 alive [KLICK]).
Anyway, a few days ago I recieved an email that the rsyncing was interrupted (I don't remember the message error; unfortunately I've deleted it), moreover I couldn't reach my backup drive any more. An OMV reboot was stopped with a message something like "fsck was interrupted with error code 8", it's log was this:

I started a live Lubuntu and checked what I thought might be wrong (SMART, badblocks etc.) with no recognizable result.
But accidentally I discovered that several partitions in my system are now formatted as ZFS?! I know for sure that at least sdc/sdc1 was an ext4 and I'm very sure that sda(x) were the usual debian system formats.
lubuntu@lubuntu:~$ sudo lsblk -fl

[I don't know why these codes are formatted differently?!]
I am very irritated at the moment: What went wrong and what can I do now with my OMV???
