Re: Docs on clustererd option of vgcreate

[Jonathan Brassow <jbrassow@redhat.com>]

The reason the results are likely so sparse is because the two modes of operation (single machine and cluster) are so similar.

Once you've setup a cluster and installed the lvm2-cluster rpm*, new volume groups that are created automatically receive the "clustered" attribute.  [Toggle the cluster attribute by doing vgchange -c[ny] <vg>]  The lvm commands stay the same as if you were running them on a single machine.**

* Of course you could compile the sources or use another install method.

** Some targets (like snapshots) are not available when using LVM in a clustered mode.

Hi

I am after a bit more documentation about the usage of the

--clustered option in vgcreate.

 

At the moment I don’t have a spare san drive with which I can experiment. My understanding is that you would set this flag when different hosts(nodes) connect to the same storage area typically a san with lvm configured.

 

I am after a bit more information describing this “clusterering” functionality in lvm and how/where it is used. The man pages on lvm and commands is a bit sparse and I am trawling through google results but not with great success at the moment.
