Hello list!
I have try to switch from 2.6.13 to 14-rc1, but this kernel breaks my
device!
The problem:
# mdadm -A -R -f /dev/md31 /dev/md1 /dev/md2 /dev/md3 /dev/md4
mdadm: no RAID superblock on /dev/md1
mdadm: /dev/md1 has no superblock - assembly aborted
md31 is a 8TB raid0 device.
the 2. dev:
# mdadm -E /dev/md2
/dev/md2:

but the md1 (the first dev) is this:
# mdadm -E /dev/md1
mdadm: No super block found on /dev/md1 (Expected magic a92b4efc, got

How can I fix this?
Can somebody help?
Thanks
