I've moved the meta disk to a RAID1 partition of ~500MB and it's working
much better, the only limiter now is no doubt the 100mbit modem - i'll
work on getting a crossover cable sorted!
I have this in my config, is it correct or should I be using [0] for
both meta disks????
on alpha {
device /dev/drbd0;
disk /dev/md4;
address 192.168.69.150:7788;
meta-disk /dev/md5[0];
}
on beta {
device /dev/drbd0;
disk /dev/md4;
address 192.168.69.155:7788;
meta-disk /dev/md5[1];
}
Thanks,
Henri
