Sorry, i'm not sure if I missed this mail.

Maybe i need to explain a couple of things first, just to make them

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:



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

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,
