Hi,
I have performed a fresh install of 12.2 M3 , with the following setup:
/ -> /dev/sda1 , ext4
/mnt/md -> /dev/md0 RAID 10 array, ext4
At boot the RAID array is not recognized ; I see some error messages when udev tries to create the array using
mdadm --incremental /dev/sdb1
Also the boot is delayed for a long time
12.572749] md/raid10:md0: active with 4 out of 4 devices
12.572777] md0: detected capacity change from 0 to 620806275072
12.824973] md0: unknown partition table
97.466489] vboxdrv: Found 4 processor cores.
Mounting the partition after the boot sequence is complete works like a charm.
I have also found a Ubuntu launchpad reference at https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/551719 which seems to be about the same problem, but I’m not sure.
Did anyone run into this or has any ideas on how to solve this?
Thanks,
Robert
