Hi all, This is a success story installing drbd 0.7.4 on 2 (mostly) identical Red Hat 9.0 boxes running kernel 2.4.7. Thought you might appreciate the feedback. Download, compilation & install was easy. Configuring /etc/drbd.conf was next - it was easy thanks to the template & comments. I made a resource called 'p4test' as I'm testing Perforce replication. When that was done, I tried starting the servers: root at p4test1:~ # service drbd start This didn't work as /dev/drbdX hadn't been created yet. After creating the devices manually (see a previous post), the servers started & connected to each other sans probleme. But then I found both volumes were (unsurprisingly!) inconsistent -- this meant I couldn't mkfs on my new mirrored device. So I stopped one drbd server, and forced the other to be a primary server ala: root at p4test1:~ # drbdsetup /dev/drbd0 primary --do-what-I-say Then mkfs worked: root at p4test1:~ # mkfs.ext3 -L p4root /dev/drbd0 After that I started up drbd on the secondary, and it started syncing. root at p4test1:~ # cat /proc/drbd version: 0.7.4 (api:76/proto:74) SVN Revision: 1537M build by spurkis at p4test1.multimap.com, 2004-09-17 15:04:12 0: cs:SyncSource st:Primary/Secondary ld:Consistent ns:276908 nr:0 dw:24724 dr:298484 al:65 bm:48 lo:0 pe:43 ua:1255 ap:0 [==========>.........] sync'ed: 54.8% (235292/512032)K finish: 0:09:48 speed: 308 (472) K/sec So I tried mounting the device: root at p4test1:~ # mount /dev/drbd0 /usr/local/perforce Again, no problems. I'll be trying out failover with Linux-HA next. I'd just like to say well done for making drbd easy to install, and (so far ;-) simple to use. Though slightly out of date, the docs have been excellent. Cheers, -Steve
