Hi all,
is use a master/master drbd (8.3.6) with clustered lvm2.
The layout is:
local LV -> drbd0 -> cluster LV -> iscsi (want to export the whole VG on
drbd0)
CMD: lvcreate -L55G CLUSTER_POOL1 system0
### local LV ###
--- Logical volume ---
LV Name /dev/system0/CLUSTER_POOL1
VG Name system0
LV UUID IBSjXj-LCpL-gcb2-tEU8-jCWU-S8DG-EJ62Dz
LV Write Access read/write
LV Status available
# open 0
LV Size 55.00 GiB
Current LE 14080
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:7
### drbd resource ###
on srv1 {
device /dev/drbd0;
disk /dev/system0/CLUSTER_POOL1;
address 192.168.222.101:7788;
flexible-meta-disk internal;
}
CMD: pvcreate /dev/drbd0 ; vgcreate -cy CLUSTER_VG1 /dev/drbd0
### clustered VG (on both) ###

all looks nice...
and now resize system0/CLUSTER_POOL1 on both nodes
<snip>
lvresize -d -L+5G /dev/system0/CLUSTER_POOL1
Extending logical volume CLUSTER_POOL1 to 60.00 GiB
Logical volume CLUSTER_POOL1 successfully resized
<snap>
CMD: lvdisplay

...hm, 35GB.. ok, try a resize

no output or something but retrun 0 (all ok?):
