Total newbie here, as of few days. Be nice!
I read the fine user guide on drbd.org but still no go.
I have drbd-8.2.5 installed on debian/etch 2.6.22.2-i686-smp.
The two nodes have logical volumes to be replicated between them.
I can't mount the volume (before or after the initial sync):
~# mount /export_www
mount: /dev/web-vg/lvweb already mounted or /export_www busy
Forgive the newbie request but what am I doing wrong?
Here's what I did on the primary node:
~# drbdadm create-md r0
v08 Magic number not found
v07 Magic number not found
v07 Magic number not found
v08 Magic number not found
Writing meta data...
initialising activity log
NOT initialized bitmap
New drbd meta data block sucessfully created.
~# drbdadm attach r0
~# drbdadm connect r0
~# drbdadm -- --overwrite-data-of-peer primary r0
A while after:
# cat /proc/drbd
version: 8.2.5 (api:88/proto:86-88)
