Unfortunately, I couldn't find the answers looking through the list archives, and I couldn't see a search function, so without further ado. I've got two identical machines (pentium 4, 2 80 gb SATA drives, 512mb ram, drbd 0.7.10, CentOS 3.3, although with the ultramonkey kernel for the heartbeat integration) which will be running as HA mailservers, with two DRBD drives drbd0 which will contain /var and drbd1 which will contain /home. The idea behind my setup is to make sure that no mail gets lost either from the spool or the home users drives in case of a system failure. The drbd drives will be running on top of two Raid partitions /dev/md2 and /dev/md3, I've created two 150mb partitions for the meta data, /dev/sda7 and /dev/sdb7. The thing is, I already have data and a filesystem present on md2 and 3, ext3 to be exact, and most of the replies I've seen on this subject seem to be aplicable to people with internal metadata, in that they advise shrinking the filesystem first (I'm assuming here, correct me if I'm wrong). Before I take the leap in changing my fstab, and mounting the drbd drives, what exactly do I need to know, then do? I'd prefer not to lose any data (although it wouldn't be the end of the world), and I'm not sure exactly what effect creating a filesystem would have on the existing data. I'd be glad to read up on it, if anyone has any pertinent links. Also, I could use some more information on heartbeat integration, most of the ones I've seen list datadisk, but in my /etc/ha.d/resource.d/ there's a drbddisk, is this the same thing? Does anyone have any links or info I can read which deal witht he latest versions of DRBD and heartbeat? Thanks for any answers, and if I've neglected to include any necessary info, please let me know. Nick
