Hi,
I am using a 8 disc scsi raid5 array on a fedora 3 system.
after a system crash, while the array was rebuilding a missing hd,
i am now unable to get this array running again.
thats all i get (/dev/sdr1 is not the one which was rebuild):
# mdadm -R /dev/md4
mdadm: failed to run array /dev/md4: Invalid argument
# mdadm -A /dev/md4 -
v /dev/sdk1 /dev/sdl1 /dev/sdm1 /dev/sdn1 /dev/sdo1 /dev/sdp1 /dev/sdq1 /dev/sdr
