# How can one change the parameter value of O2CB_HEARTBEAT_THRESHOLD?
This parameter value could be changed by adding it to
/etc/sysconfig/o2cb and RESTARTING the O2CB cluster. This value should
be the SAME on ALL the nodes in the cluster.
If you have the latest o2cb init script, "/etc/init.d/o2cb configure" will
allow you to add the value too.

Hi,
According to FAQ Q69 , Q70 about O2CB_HEARTBEAT_THRESHOLD
So I use Q69 give this formula the default O2CB_HEARTBEAT_THRESHOLD
should be 12s ?
O2CB_HEARTBEAT_THRESHOLD = (((12) / 2) + 1) = 7
So If I need to have 10 as recomended by DRBD the default time out is 18s ?
O2CB_HEARTBEAT_THRESHOLD = (((18) / 2) + 1) = 10
What is the command to change it under debian ?
I've got a "permission denied" using this :
echo 10 > /proc/fs/ocfs2_nodemanager/hb_dead_threshold
Regards
Sébastien
