[Wylug-discuss] drbd any info on what to watch out for

[sh2515+linux]

Hi

I am setting up a system for a client with important digital assets, 
just wanting others knowledge of any known issues using drbd in this 
configuration.

setup:
2 nodes
2 lv's on each node
drbd set in primary/secondary over the lv's
ext4
ubuntu 12.04LTS (valid reasons for using this over rhel or derivative)
pacemaker/heartbeat
offsite backup

Does anyone have any advice or know of any pitfalls I should be aware 
of before implementation?

Scott
