Hi guys, I’ve found this in
/sys/kernel/debug/gfs2/fsname/glocks H: s:EX f:tW e:0
p:22591 [jsvc] gfs2_inplace_reserve_i+0x451/0x69a [gfs2] H: s:EX f:tW e:0

[pdflush] gfs2_write_inode+0x57/0x152 [gfs2] The application running
is confluence and has 184 thread. The other nodes work fine but that specific
node is having issues obtaining locks when it’s time to write? Dave From: linux-cluster-bounces@xxxxxxxxxx
[mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of David Hill Hi guys,
We have a GFS2 cluster consisting of 3 nodes. At this
point, everything is going smooth. Now, we add a new node with more CPUs
with the exact same configuration but all
transactions on the mount run very slow. Copying a file to the mount is done at
about 25kb/s when on the three other nodes, everything goes smooth at about
7MB/s. CPU on all nodes is idling at some point,
all cluster process are kind of sleeping. We’ve tried the ping_pong.c from apache and
it seems to be able to write/read lock files at a decent rate. There’s other mounts on the system using
the same fc card/fibers/switches/san and all these are also working at a decent
speed... I’ve been reading a good part of the day,
and I can’t seem to find a solution.
