Regardless of the filesystem (i've used reiserfs, xfs, ext3), whenever I mount a fresh DRBD partition I get some nasty kernel messages.
This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using DRBD v0.7.11 (pulled from Debian "testing").
This is what I did to create the partition.
On both nodes I created a new LVM storage device and started DRBD: # lvcreate -L1G -n drbdtest xen # /etc/init.d/drbd start
The rest I did on the primary node.
Set the node primary: # drbdadm -- --do-what-I-say primary all
Check everything looks fine: # dmesg | tail ; cat /proc/drbd
Make the filesystem: # mkfs.ext3 /dev/drbd0
Mount: # mount /dev/drbd0 /mnt/drbd0
Then I get the following kernel messages:

Though, the partition appears to have mounted okay:
Nov 1 13:52:13 localhost kernel: kjournald starting. Commit interval 5 seconds Nov 1 13:52:13 localhost kernel: EXT3 FS on drbd0, internal journal Nov 1 13:52:13 localhost kernel: EXT3-fs: mounted filesystem with ordered data mode.
Any ideas? I saw similar post to the drbd list from last January, but no one had any comments.
I've sent this message to drbd-user as well.
Thank you. .:. jeremy
