[Linux-cluster] GFS Node Limit?

[Richard Mayhew]

I have increased the number of journals on each FS from the 8 previously
discussed to 16. At present the max number of servers that I intend on
using will be 10, leaving 6 journals open for expansion. When trying to
mount the 6th server, I end up with the same problem. The mount hangs
until I remove a mount from another system before the 6th system is able
to complete the GFS mount.

After adding on full verbosity on the gulm lock server I still can't see
anything of interest. Dmesg offers no clue either. The only message I'm
seeing is the following : "GFS Kernel Interface" is logged out. fd:10"
etc.

After searching the net, the only advice I can find is to increase the
number of journals to at least the number of nodes. This I have done
with no success....

Any other ideas?

I have 4 mounts of 50GB each.
Each mount has 8 Journals...(this amount I found in the manual
somewhere)

Is this a prob?

Do you have a recommended FS layout etc?

How many journals on your filesystem?
