RHEL 5.3: Need help with filter statement in /etc/lvm/lvm.conf

[lbholde]

Hi,

I have a RHEL 5.3 server attached to an EMC Clariion. There are 24 36gb LUNs presented to my server. I have 4 paths to each LUN. I'm using native Linux multipathing. Consequently, each LUN shows up 5 times (one for each path, and one for the multipath). I also have two internal logical drives, /dev/sda and /dev/sdb, and I want LVM to see them.

I'm trying to get LVM to ignore the individual paths and I need help making my filter statement correct in /etc/lvm/lvm.conf. Here is my filter line:

filter = [ "a/dev/sda/", "a/dev/sdb/", "a/dev/mpath/.*/", "r/.*/" ]

Here are my devices:

Similar messages show up every time I reboot the server.

Any ideas on how to make my filter statement correct?

Thanks!
