Extend a shared VG in a 2 node cluster

[Luca_11]

Hi,
I need to create a new LV on a shared VG (vg_name) in a two node (N1 andd N2) active-passive cluster.
The VG changes have to be passed in the passive node (N2).

I think to go in this way:
1)N2 vg_export vg_name (del info about vg_name on N2)
2)N1 lvcreate -L size -n lv_name vg_name
3)N1 vgexport -m mapfile -s -p -v vg_name
4)N1 rcp N1:mapfile N2:mapfile
5)N2 mkdir vg_name
6)N2 mknod group c 64 0x010000
7)N2 vgimport -m mapfile -s -v vg_name

Somebody see something strange?

Thank you
Luca

looks fine to me.
Just be sure to test the VG on N" once this has been done.

The only other thing I would do is to make sure that the minor number that you're using for the group file is the same on both machine. It doesn't really hurt if they're different, but for consistency, they should be the same.
