Hi(Sorry for the long post),
I'm trying to configure a primary/primary configuration with OCFS2 in
Debian. I start with /etc/init.d/drbd start, everything looks ok.
monaco:/etc# /etc/init.d/drbd start
Starting DRBD resources:
monaco:/etc# cat /proc/drbd
version: 8.0pre3 (api:82/proto:80)
SVN Revision: 2169 build by root at monaco, 2006-06-20 09:47:26
0: cs:Unconfigured
After it, i type:
monaco:/etc# drbdadm create-md mysql
everything ok by now
After it, when I type:
drbdadm -- --overwrite-data-of-peer primary all
I get the kernel oops below... My mysql partition in LVM is 3G
partition in both servers(one server is in VG01 and in the other is
VG00 look at drbd.conf).
Thanks for the attention, I hope a solution to my problem.
