Hello everyone! This is my first time with DRBD, and so far it's been interesting. I am attempting to use it with OpenFiler (CentOS), as well as heartbeat. I am not quite sure if I got the mirror to work, but the drbd service starts on both machines. --- Here's as snapshot from my /etc/drbd.conf on openfiler { device /dev/drbd0; disk /dev/hda3; address 192.168.1.107:7788; meta-disk internal; } on openfiler2 { device /dev/drbd0; disk /dev/hda3; address 192.168.1.108:7788; meta-disk internal; } --- Here's the output from /proc/drbd: version: 0.7.6 (api:77/proto:74) SVN Revision: 1663 build by root@aztec.corp.xinit.com, 2005-03-08 13:59:43 0: cs:Connected st:Primary/Secondary ld:Consistent ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 My question now: I am not able to a) put a filesystem on /dev/drbd0 b) mount /dev/drbd0 on /mnt/disk thus c) not being able to see any working mirrors. Is there a newby Howto that explains in simple steps the setup configuration? Greets, Rainer Rohde Rainer A.
