[Linux-cluster] Netapp snapdrive connect doesn't like clustered volumes

[yu song]

lvm part still needs to be specified in the service section if you want to
follow a proper way.

locking_type =3  is correct.. you can use lvmconf --enable-cluster to
enable clvmd, which actually does change locking type to 3 anyway.

when you create a new vg controlled by clvmd.. after
pvcreate/vgcreate/lvcreate/mkfs.ext3... don't forget to run lvchange -an
vg0/ha_lv

nothing special about tagging is requires as far as I am aware..  you might
need to look at filter section to ensure the volumes are not blacklisted.
