Hi Alan,

It's perfectly fine to enable the clustered bit with vgchange -cy,
and that flags the entire vg and all the lvs inside it.
You should probably unmount-then-mount the gfs file system on all
the nodes after that, just to be safe.  I don't think you need to
remount on the node that did the gfs_grow though.

The missing clustered bit is probably the cause of all your grief,
so I wouldn't bother opening a ticket, unless you can recreate
the failure with the clustered bit on, after umount-then-mount.
