Hi all,
I'm trying to set up HA with DRBD and Heartbeat on two identical RedHat
VM's hosted on Windows VirtualBox. The details about the server(s) drbd
biuld and config are given below:
[root@cpvmdc1 ~]# uname -a
Linux cpvmdc1 2.6.18-229.el5 #1 SMP Tue Oct 26 18:54:44 EDT 2010 x86_64
x86_64 x86_6
so strange that I'm sure I
formated drbd partition with ext3 but is showing as ext2 in mount:
[root@cpvmdc1 httpd]# mount
/dev/drbd0 on /drbd0 type ext2 (rw)
.
.
Thanks,
Igor

Hi,
According to https://docs.linbit.com/docs/users-guide-8.4/#s-resizing,
when resizing DRBD 8.4 device online one side of the mirror needs to
be Secondary. I have dual primary setup with Pacemaker and GFS2 as
file system and wonder if I need to demote one side to Secondary
before I run:
drbdadm
Nevermind decided not to be lazy (saturday and all that) and do it
properly. Done now.
