[Linux-cluster] Making a cloned clustered VG mountable on a backup media server?

[rhurst at bidmc.harvard.edu]

I am having problems making a clustered VG visible on a backup media
server.

The originating RHEL cluster issues the CLARiiON cloning process, and it
completes successfully, to another volume.  That clone volume LUN is
visible to the backup media server (outside of the cluster) only.

Q1: What do I need to do on the backup media server's LVM to activate
this newly-made VG?  vgscan --mknodes is not helping any, but I do see
some SCSI references, i.e., /dev/sdz to its 420GB sized disk.  Is there
a safe way to vgexport / vgimport the original VG map to this server?

Q2: I loaded GFS software on the backup media server, so do I need to
modify the VG's lvols superblock to a changed PROTO value of nolock to
make it mountable for backup?

Thanks.
