hello

when I run ping_pong on a node, then the whole network is slow or falls out completely.

what ist wrong?

ping_pong -rw /clusterfs/data/test.odt 3

system: centos 6.4
cluster file system: gfs2

ctdb-1.0.114.5-3.el6.x86_64

Assuming /clusterfs/data/test.odt is on a gfs mount, this is nothing Samba or ctdb could do anything about. Please contact the GFS people. If /clusterfs/data/test.odt is not a direct GFS mount but on a cifs client mounting a clusterfs remotely via Samba and ctdb, please re-open this bug.

Thanks,

Volker
