[Linux-cluster] GFS2 - disable plock limit on a live cluster

[david robertson]

Hello, I have a cluster of 11 hosts all sharing the same volume.
Currently, the default plock limit of 100 is enabled.  The catch is,
this is a live cluster, and it can not be taken offline.

My question is, can I modify the cluster.conf file with the usual
lines (dlm plock_ownership=1, plock_rate_limit=0, etc) and just do
"ccs_tool update" and be done with it, or does each node have to be
rebooted?
