[linux-lvm] resize and snapshots with clvm

[Andreas Pflug]

I'm using clvm over corosync, sharing iscsi hosted PVs. I'm generally 
using Debian squeeze/wheezy, lvm2 2.2.95.

What I'm missing is the possibility to resize a LV or taking a snapshot 
of it while a volume is used on one node. I'd expect this to work on the 
active node, if the volume is inactive on all other nodes. But when I 
try that, I get
cluster request failed: Invalid argument
   Failed to suspend <logvol>

I've seen the message 
https://www.redhat.com/archives/linux-lvm/2013-January/msg00006.html ,
Compiled 2.2.98 with the patch applied 
(--with-clvmd=cman,corosync,openais --with-cluster=internal), no further 
success.
What can I do?

Regards,
Andreas
