Hello! I've got a drbd setup with 2 drbd partitions in an active/active failover Cluster. After measuring the performance of the disks we found out that the Adaptec 2120s Controller has a very poor Performance. (only 20Mb/s write) I decide to change the SCSI-Controller to an LSI 320-2x SCSI Controller which has about 80 MB/s write Performance. (My Setup is with 6x 147Gb SCSI 15k Disks in Raid 10) Now i have a third Server with exact the same Hardware, but the new Contoller built in. I've made a Raw Offline Backup from the Disks (with Netvault Backup) and want to restore the data on the new Server with the new Controller. Then i changed the mount points from /dev/iso/hda1 to /dev/sda1 for example to fit the new hardware. But now I've got a problem with drbd: Jun 10 10:22:09 po-b kernel: drbd: initialised.

I think that something with the raw backup and restore process failes. But i dont know another way to perform an upgrade(test-upgrade) of the SCSI Controller. Is there another way or i am on the right one? :) thx S.Novak
