I'm not sure I understood your setup right. So there is actually two
DRBD resources?
Your config should look like this on both nodes then (untested example
config!)
resource PartitionA {
meta-disk internal;
device /dev/drbd0;
disk /dev/vg01/share; # <- Partition A: always vg01
on NodeA {
address 2.2.2.150:7788;
}
on NodeB {
address 2.2.2.151:7788;
}
}
resource PartitionB {
meta-disk internal;
device /dev/drbd1;
disk /dev/vg02/share; # <- Partition B: always vg02
on NodeA {
address 2.2.2.150:7789;
}
on NodeB {
address 2.2.2.151:7789;
}
}
Also, sorry for asking you to take Dan's config verbatim. I just noticed
it was a pseudo-config.
Regards,
Felix
