Hi Rafael,
Of course, that is what I was telling you the other day, your script works fine, but I just wanted to twist a little clvm.
The prerequisites are already setup (locking type, dm-mp, lvm, etc...).
The only thing that disturbes me is that you can bypass under certain conditions the locking.
Thanks for the help

Maybe i need to explain a couple of things first, just to make them
clear.
As part of the use of the lvm-cluster.sh resource script, you need to:
1.- Configure properly the lock type into lvm.conf to type 3 (example
into this link:
https://www.redhat.com/archives/linux-cluster/2009-July/msg00253.html
)
2.- Configure your multipathing software
3.- Create your Physical Volumes
4.- Configure your Volume Groups as clustered Volume Groups
5.- Create your Logical Volumens into the clustered Volume Groups
6.- And, and the not so obvious, de-activate all the Logical Volumes you
plan to use as exclusive Logical Volumes (using exclusive flag).
De-activation can be done with "vgchange -an volgrp01/logvol01" or
similar command.
If you don't do step 6, you will receive an error message when executing
"lvchange -aey volgrp01/logvol01". This command is executed (with the
proper volume group and logical volume names) internally in the resource
script.
I designed the lvm-cluster.sh resource script to be verbose, maybe you
can copy here your logs (default to /var/log/messages on RHEL systems).
Cheers and thanks,
Rafael
