Hi,
I''am trying to use DRBD with XEN 3.0, the xen kernel is an 2.6.12.6 and
i am using DRBD 0.7.14.
The primary node is an opensuse 10 linux (not virtualized).
The 2 volumes are LVM logical volumes with internal metadatas, there
size is 54G.
The secondary node is an opensuse 10 also but running over xen domain-0.
When i setup drbd, synchronisation starts, but the whole system just
reboots a few seconds after.
I don''t know if the problem is xen or drbd related ? Unfornately I have
no traces on the xen node.
I set "ecbo 60 > /proc/sys/kernel/panic", but it doesn''t
seem to be a
kernel panic, but a "xen" panic.
Please help.

# 1GB / ( 10MB/sec ) ~ 102 seconds ~ One Minute and 42 Seconds.
# BTW, the hash algorithm works best if the number of al-extents

# meta-disk is either ''internal'' or
''/dev/ice/name [idx]''
#
# You can use a single block device to store meta-data
# of multiple DRBD''s.
# E.g. use meta-disk /dev/hde6[0]; and meta-disk /dev/hde6[1];
# for two different resources. In this case the meta-disk
# would need to be at least 256 MB in size.
#
# ''internal'' means, that the last 128 MB of the lower
device
# are used to store the meta-data.
# You must not give an index with ''internal''.
