Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.
I'd think it's pretty simple.
You've defined two "HOST_2" instances. Try fixing that first.
Also, I assume you can point the device to anything that a filesystem
can sit on...
This is mine, works like a charm:
resource nfs {
protocol C;
incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep
60 ; halt -f";
disk { on-io-error panic; }
syncer {
group 0;
rate 30M;
}
on lvs01.mikehost.net {
device /dev/drbd0;
disk /dev/sda4;
address 192.168.1.101:7788;
meta-disk internal;
}
on lvs02.mikehost.net {
device /dev/drbd0;
disk /dev/sda4;
address 192.168.1.102:7788;
meta-disk internal;
}
}
