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!<br>
<br>
I have this in my config, is it correct or should I be using [0] for
both meta disks????<br>
<br>
on alpha {<br>
device /dev/drbd0;<br>
disk /dev/md4;<br>
address 192.168.69.150:7788;<br>
meta-disk /dev/md5[0];<br>
<br>
}<br>
<br>
on beta {<br>
device /dev/drbd0;<br>
disk /dev/md4;<br>
address 192.168.69.155:7788;<br>
meta-disk /dev/md5[1];<br>
}<br>
<br>
<br>
Thanks,<br>
<br>

I hope that home router at least has Gigabit., though the best connection for
DRBD would be a simple cable without any switch in between.

Are the RAID devices themselves even synchronized yet? What does
cat /proc/mdstat say?
Also: never put a drbd meta disk on a MD RAID 5. Its painfully slow (and may
be a reason for what you see). RAID 1 should be ok.
