Re: DRDB Failover Not Right - Not Replicating Share
[In reply to]

Ive had a look at the problem you suggested with activating the VG but I
don't think its that. When I fail over I can only see /dev/data/filer
instead of /dev/data/filer/vms which is on my Master.
I can't give you a print out of vgdisplay -vvv just now, another problem
seems to have cropped up.
I wanted to re-make my Volume Groups to see if it was that and made another
problem. When re-making it didn't work so looked into it further.
Ive ran these commands in order (below) and now it won't failover correctly:
:-((
vgchange –a n <volume group name>
vgremove <volume group name>
pvscan
pvremove /dev/drbd1
pvcreate /dev/drbd1
vgcreate data /dev/drbd1
lvcreate -L 400M -n filer data
What other things could be causing only the share not to display? Would
using software RAID /dev/md0 be anything to do with it?

Then most likely the data you think you are replicating
is actually not even on DRBD?
Forgot to activate the vg after switchover?
What says
vgdisplay -vvv
