Florian,
It does work, but can be challenging when it comes to stability. We still have
2 zones build with CLVM and we're activity migrating away from it. The major
problem is that it complicates host configurations and you really need a quorum

I’ve spent quite a bit of time getting CLVM to work with KVM (in this case on
CentOS6+7) – and my experience is it’s not fit for purpose, suffering a lot of
stability issues. I do know there are others in the community who may have got
this to work in the past, so interested to
Hi,
as the cloudstack documentation explains CLVM is not supported with Cloudstack:
"The use of the Cluster Logical Volume Manager (CLVM) for KVM is not officially
supported with CloudStack."

Hi guys,
I want to check corrupted VHD on a XenServer cluster with LVM over ISCSI.
This is the VHD I want to check:

Jeremy,
Secondary Storage has to be NFS so the easiest way to achieve this would be to
create a VM which can present the CLVM storage via NFS.

I was curious on if I could use CLVM as secondary storage.
I want to use the same clustered storage solution that I am using for Primary.
How would I go about adding that option into the couldstack UI.
Is it possible to do it via CloudMonkey? Could I manually add it via the DB?

Could any one help explain the difference of use ShareMount/OCFS2 and CLVM as

Our team are building Cloudstack with ISCSI/CLVM as primary storage.
In this environment a virtual machine cannot be set with HA option, option

Hi devs,
I think I have found a bug affecting a primary storage migration if
the source and destination volume are on a CLVM storage.
So far I could follow the trail at :
- secondary storage is mounted on the source host with a new template id
- cp is issued to copy /dev/volgrpoup/uuid CLVM LV

I suppose there isn't much people running different CLVM pools in the same

I suppose that some code was added to do a simple copy when format is
the
same, this wasn't the case with 4.1.1 version.

Hi,
I've just watched Marcus Sorensen's presentation on CLVM on youtube and
he was mentioning that migrating a VM with snapshots will make the
snapshots disappear.
Can anyone testify if this is still the case?
Since at it, are there any alternative ways of using a multipathed

I'm trying to join a new node into an existing 5 node CLVM cluster but I
just can't get it to work.
When ever I add a new node (I put into the cluster.conf and reloaded with

to gain the quorum and starts to
lume group, but... Still the same
