Hi,
Im mounting a shared storad with "raid5 in hardware" -> lvm -> drbd -> ocfs2
with two identical servers.
Everthing its gonny rigths, but now, in test time, drbd is often in split
brain condicion.
The two server is connect by a cross cable with a gigabit ethernet
connection.
My messages log file:
Apr 11 14:05:06 node2 kernel: drbd10: Split-Brain detected, dropping
connection!
Apr 11 14:06:14 node2 kernel: drbd10: Split-Brain detected, dropping
connection!
Apr 11 15:13:41 node2 kernel: drbd10: Split-Brain detected, dropping
connection!
Apr 11 15:35:18 node2 kernel: drbd10: Split-Brain detected, 0 primaries,
automatically solved. Sync from peer node
My drbd.conf file:
