i have ubuntu 10.04 machine use file server. have raid5 array built mdadm 3 component disks worked until recent upgrade (i'm not sure broke though). array /dev/md0 , set mount @ /var/media on bootup.
*now*, when system cold boots hangs partway through bootup sequence , throws following error:
disk drive /var/media not ready yet
press s skip ...
once "s"kip manually, can see lower in boot sequence mdadm gets called , assembles drive, , once booted system can "mount -a" , array mounts properly.
so... gut feeling portion of 1 of upgrades changed order in things called, , "mdadm assemble" not triggered until after system tries mount drives. problem don't know stuff controls boot sequence enough dig in right place.
workaround can remove entry /etc/fstab, (of course) system won't auto-mount array. it's better boot process hanging because least can fix remotely, i'd know
1) why broke in upgrade , known problem?
2) how auto-assembles , auto-mounts array on bootup.
thanks!
1) don't know
2) need check mdadm.conf make sure has correct array directive. run 'update-initramfs -u'
might want post mdadm.conf , output of mdadm --detail /dev/md0
