I have a situation where, after a reboot, the volumes that I created
under LVM2 do not exist. Here is my configuration..
Kernel version 2.6.16.9
LVM version: 2.01.04 (2005-02-09)
Library version: 1.01.04 (2005-08-02)
Driver version: 4.5.0
Drbd version 0.7.17
I created a physical volume on /dev/md2 of my hard drive. I then created
a volume group called rootvg. I then created several logical volumes,
two of which are called drbdpv00 and drbdpv04. In the /dev directory I
have device files drbd0 and drbd4 with a major number of 147.
My drbd.conf looks like this:
resource drbdpv00 {
# use the synchronous protocol
protocol C;
startup {
wfc-timeout 5;
degr-wfc-timeout 120;
}
syncer {
rate 20M;
group 0;
}
on node1 {
device /dev/drbd0;
disk /dev/rootvg/drbdpv00;
meta-disk /dev/rootvg/drbdmeta[0];
address 192.168.0.171:7790;
}
on node2 {
device /dev/drbd0;
disk /dev/rootvg/drbdpv00;
meta-disk /dev/rootvg/drbdmeta[0];
address 192.168.0.172:7790;
}
This should allow /dev/drbd0 and /dev/drbd4 to use actual disk space for
creating volumes.
Node1 is up and working perfectly. This was an actual working linux
cluster before a botched upgrade on node2, thus I had to rebuild it
after it became unbootable.
On node2 I could not create a physical volume until I unhooked the
crossover cable between the two nodes and made node2 primary. I would
get a read only error. After making node2 primary, I was able to create
the physical volumes on /dev/drbd0 and dev/drbd4 with no problem. I
created volume groups and logical volumes under that physical volume. I
rebooted node2 and when the machine came back up, the physical volumes
were gone. Node2 was back in a secondary state as far as drbd was
concerned, which I did expect. When the machine was rebooting, drbd came
back up fine.
I would appreciate any help you could offer on this, as I am at wits
end.
