There are two servers, each with 16 SATA local disks. The servers areconnected to each other through the 10Gbps interface. The disks arearrayed in RAID1 pairs done via hardware, and therefore the OS sees 8disks. These 8 disks are configured in an active-active DRBD setupbetween the two machines. The DRBD devices are formatted as OCFS2.The OCFS2 cluster configuration is done using the same 10Gbpsinterface used by DRBD.

Yes.

The backup server never mounts its filesystems. The errors I reportedalways happen on the two servers, never on the backup server. I havealso run fsck on all backup filesystems, but never found any errors tobe corrected.
