Hi! Got this problem on Virtual Machine Replication & Failover with VMWare Server & Debian Etch (4.0) howto. Hope u can help me fix the problem. Here's the portion which gave the error: Linux:~# drbdadm up all Lower device (/dev/md3) is already mounted Command 'drbdsetup /dev/drbd0 disk /dev/md3 internal -1 --on-io-error=detach' terminated with exit code 20 My machine is currently at RAID 1.

I know i have to unmount the RAID Partition. But what's the proper command/configuration in the drbd.conf to load it as RAID 1 partition. Is it possible? Also, I'm using a Gigabit NIC. In the /etc/drbf.conf syncer { rate 1024M; # Use more if you have a Gigabit network. Speed is in Kylobytes. e.g.: 10M = 10Megabytes group 1; Tried rate 1024M but there's an error as follows: :~# drbdadm up all /etc/drbd.conf:17: rate 1024M => 1024000K out of range [1..700000]K. How can I fix it? What the valid options? Thank you so much and more power!
Hi, Got some progress here. Error regarding the RAID device is gone already. Here's what I did in case somebody encountered the same problem: I uncommented the /etc/fstab RAID partition and made this entry: /etc/drbd.conf on server1.domain.com { # Use the EXACT hostname of your server as give by the command "uname -n" device /dev/drbd0; # drbd device ID disk /dev/md3; # physical disk device , check your partitioning scheme !! address 192.168.1.200:7789; meta-disk internal; # I use internal metadata storage } on server2.domain.com { device /dev/drbd0; disk /dev/md3; address 192.168.1.100:7789; meta-disk internal; } I followed the rest of the howto and everything worked fine. However when I shutdown the primary server I got this error: drbd0: worker terminated drbd0: unacked_cnt 1935 drbd0: Sorry, I have no access to good data anymore. Kernel panic - not sysncing: drbd0: Sorry, I have no access to good data anymore. Any idea? Thank you and more power!
I'm sorry, I can't find anything there that may address my problems. I noticed that the /var/vm is not really mounted /dev/drbd0 #fdisk -l Disk /dev/md3: 65.5 GB, 65596489728 bytes 2 heads, 4 sectors/track, 16014768 cylinders Units = cylinders of 8 * 512 = 4096 bytes # df -h Filesystem Size Used Avail Use% Mounted on /dev/md2 9.2G 1.1G 7.7G 13% / tmpfs 1011M 0 1011M 0% /lib/init/rw udev 10M 76K 10M 1% /dev tmpfs 1011M 0 1011M 0% /dev/shm /dev/md0 228M 13M 204M 6% /boot /dev/drbd0 should be mounted as /var/vm which is also my RAID /dev/md3. But my RAID device seem not mounted as can be seen above. Any comments?
