[linux-lvm] Fixed! (was: Re: Two questions about cluster support (2 problems, actually))

Thanks for the reply, Milan!

I had made the change to the 'filter' argument, but I was using 'filter
= [ "a|drbd.*|", "r|.*|" ]'. I switched to 'filter = [ "a|^/dev/drbd|",
"a/sd*/", "r/.*/" ]' and started 'clvmd'. This seems to have solved the
problem, so thank you.

If I may ask another question though;

My DRBD device is '/dev/drbd0' which sits on either node's
'/dev/san0x/lv02'. When I ran 'pvcreate /dev/drbd0' the PV was created
successfully and 'pvdisplay' shows the new PV on both nodes. However, I
see this:

# pvdisplay
--- Physical volume ---
PV Name /dev/sda2
VG Name san02
PV Size 465.51 GB / not usable 14.52 MB
Allocatable yes
PE Size (KByte) 32768
Total PE 14896
Free PE 1407
Allocated PE 13489
PV UUID ru7tmz-Qd4d-aatg-4ReY-TPPq-gMll-Z5ZOkL

"/dev/san02/lv02" is a new physical volume of "399.99 GB"
--- NEW Physical volume ---
PV Name /dev/san02/lv02
VG Name
PV Size 399.99 GB
Allocatable NO
PE Size (KByte) 0
Total PE 0
Free PE 0
Allocated PE 0

Note that the 'PV Name' is '/dev/san02/lv02' but the device passed was
'pvcreate /dev/drbd0'. Is this correct? I'd expect it to show the DRBD
device, not the DRBD's underlying logical volume.

I switched back to my old syntax and added an entry for 'sdX' devices, restarted clvmd on both nodes and every seems to be fine now! Here is my latest, working, filter line:

filter = [ "a|drbd.*|", "a|sd.*|", "r|.*|" ]

Thanks for the help! I'll be looking forward to testing out the fix in CentOS 5.5. :)
