Hello, I'm very new to drbd, and I have been going over the documentation
and mailing list archives the past few days to help me get started. But
I've reached a point were I need some help.
I think what I am trying to accomplish should be fairly simple. I have two
nodes and I'd like to replicate the '/var/log' file system between the
two.
I have drbd compiled and installed (I believe correctly), and I'm running
in to a couple of problems...
1. On one node when I run 'drbdadm up all' I get the following error (I
did run the mknod command as the documentation specifies):
can not open /dev/drbd0: No such device or address
Command '/sbin/drbdsetup /dev/drbd0 disk
/dev/mapper/VolGroup00-LogVol00_varlog internal -1 --on-io-error=detach'
terminated with exit code 20
2. On the other node when I run 'drbdadm up all' I get the following
error:
Lower device (/dev/mapper/VolGroup00-varlog) is already mounted
Command '/sbin/drbdsetup /dev/drbd0 disk /dev/mapper/VolGroup00-varlog
internal -1 --on-io-error=detach' terminated with exit code 20
I understand that the file system cannot be mounted when drbd tries to use
it, but I'm not sure how to configure this to work correctly. Is there a
way to get drbd to mount the file system on startup?
I am running...
RedHat EL 4
heartbeat 2.0.2-1
drbd 0.7.13
drbd.conf (I only changed the host information, and left everything else
default):
on left_host {
device /dev/drbd0;
disk /dev/mapper/VolGroup00-varlog;
address 10.10.10.11:7788;
meta-disk internal;
}
on right_host {
device /dev/drbd0;
disk /dev/mapper/VolGroup00-LogVol00_varlog;
address 10.10.10.12:7788;
meta-disk internal;
}
Your friendly neighborhood SA,
