You can't have non-clustered LVs in a clustered VG (though it doesn't look like you're doing that). The activation for local VGs should then have the --ignorelockingfailure flag passed to the LVM commands, which should also only be activating the local VG) so it will carry on even if the cluster locking attempt fails. > The second issue is that GFS doesn't seem to allow an automatic way to > actually mount the GFS partitions once clvmd is started.
