I recently installed Xen on top of a DRBD block device. At first this
seemed to go great, but now my xen guest seems to be having a hard
time finding its partitions. I thought I'd try to mount the
partitions manually and see what's up, but low and behold, I cannot
mount them either.
Xen is supposed to be looking at /dev/drbd2, so if I use fdisk to
look at /dev/drbd2, I see:
Disk /dev/drbd2: 31.4 GB, 31474057216 bytes
255 heads, 63 sectors/track, 3826 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/drbd2p1 * 1 13 104391 83 Linux
/dev/drbd2p2 14 3826 30627922+ 8e Linux LVM
So it *seems* like I should be able to mount /dev/drbd2p1 or /dev/
drbd2p2. Alas:
# mount /dev/drbd2p1 /mnt
mount: special device /dev/drbd2p1 does not exist
# mount /dev/drbd2p2 /mnt
mount: special device /dev/drbd2p2 does not exist
Why doesn't this work? Are there DRBD logs I can look at? /var/log/
messages isn't giving me anything.
