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.
