Hi all,
same problem for me: today after a reboot of a cluster node, clvmd could
not start properly anymore since pvscan hangs.
If I try to start vgscan on the other node it hangs too!! If I 'strace'
on pvscan I can see it stops while reading...
It's a cluster of two nodes, with quorum disk (two_node="0"), offering
several VMs installed on raw partitions in a CLVM environment.
It's running version 5.4, x86_64 , with the following packages:
cman-2.0.115-1.el5_4.3
rgmanager-2.0.52-1.el5_4.2
lvm2-2.02.46-8.el5_4.2
lvm2-cluster-2.02.46-8.el5_4.1
kernel-xen-2.6.18-164.2.1.el5
kernel-xen-devel-2.6.18-164.2.1.el5
xen-3.0.3-94.el5_4.2
xen-libs-3.0.3-94.el5_4.2
Any suggestion on what can I check/change/install? I don't have any idea
on what happened...
Thanks,
Daniela

Hi all,
i use redhat cluster my os version is 5.4. I have a three-node cluster
and clustered VG (XenVG) with many LV (one for each VM). After a cluster
reboot I’m not able to restart clvmd anymore due to vgscan hangs.
Is there a way to convert the clustered VG to a non-clustered one? I
tried changing the locking_typ parameter from 3 to 1 but it wasn’t the
right solution.
You can remove the cluster flag from a VG with the following command
vgchange -cn <vg> --config 'global {locking_type = 0}'
If you're amenable it would be helpful to try and debug this. Can you add
CLVMDOPTS="-d2"
to the file /etc/sysconfig/cluster
and post the clvmd parts of system to me please.
Thanks
Chrissie
