configuration simplicity point of view, it could be convenient to add the

volume activation in exclusive mode and mounting it. I think this is the most
common usage of the fs resource. In this way, I don’t need to create two
resources for each filesystem (one for the logical volume and one other for the
fs) and I can be sure a filesystem can not be mounted by hand in another node (as
it has been activate exclusively in the node running the service).<o:p></o:p></span></font></p>

<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Sorry,
i'm not sure if I missed this mail.<br>
<br>
Maybe i need to explain a couple of things first, just to make them<br>
clear.<br>
<br>
As part of the use of the lvm-cluster.sh resource script, you need to:<br>
<br>
1.- Configure properly the lock type into lvm.conf to type 3 (example<br>
into this link:<br>
<br>
<a href="https://www.redhat.com/archives/linux-cluster/2009-July/msg00253.html"
target="_blank">https://www.redhat.com/archives/linux-cluster/2009-July/msg00253.html</a><br>
<br>
)<br>
<br>
2.- Configure your multipathing software<br>
<br>
3.- Create your Physical Volumes<br>
<br>
4.- Configure your Volume Groups as clustered Volume Groups<br>
<br>
5.- Create your Logical Volumens into the clustered Volume Groups<br>
<br>
6.- And, and the not so obvious, de-activate all the Logical Volumes you<br>
plan to use as exclusive Logical Volumes (using exclusive flag).<br>
<br>
De-activation can be done with "vgchange -an volgrp01/logvol01" or<br>
similar command.<br>
<br>
If you don't do step 6, you will receive an error message when executing<br>
"lvchange -aey volgrp01/logvol01". This command is executed (with the<br>
proper volume group and logical volume names) internally in the resource<br>
script.<br>
<br>
I designed the lvm-cluster.sh resource script to be verbose, maybe you<br>
can copy here your logs (default to /var/log/messages on RHEL systems).<br>
<br>
Cheers and thanks,<br>
<br>
Rafael<br>
