Public bug reported:
Binary package hint: mountall
I have a RAID 1 partition across /dev/sdb3 and /dev/sdc3 which was
created with mdadm in 9.10. It worked fine through upgrades to 10.04
and 10.10, but in 11.04 it fails to mount at boot time.
I updated my /etc/fstab to account for the apparent device name change
from /dev/md0 to /dev/md_d0 in 11.04. This allowed me to mount the RAID
partition manually, but it still does not mount at boot. I get the
error "The disk drive for /mnt/data is not yet ready or not present".
If I drop into the manual recovery shell, however, a "mount /mnt/data"
succeeds.
If I drop into the manual recovery shell, but exit without doing
anything, the subsequent invocation of mountall still fails to mount the
partition. So it appears that this is not a timing issue.
dmesg shows the RAID as active, with no errors, apparently before
mountall is invoked. /proc/mdstat concurs.
mountall 2.25ubuntu1
