[Linux-cluster] CS5 / timers tuning (contd)

Hi Lon

Thans again, but that's strange because in the man , the recommended
values are :
intervall="1" tko="10" and so we have a result < 21s which is the
default value of heart-beat timer, so not a hair above like you
recommened in previous email ...
extract of man qddisk :

         interval="1"
            This is the frequency of read/write cycles, in seconds.

         tko="10"
            This  is  the  number  of  cycles  a node must miss in order to be
            declared dead.

?

PS : " don't recall if there's a way to do it from
cluster.conf"
 yes we can change the deadnode_timeout in cluster.conf :
<cman deadnode_timer="DEADNODETIMER_VALUE"/>

Thanks
Regards
Alain Moullé

Right, interval + tko

interval * tko = qdisk timeout

See the qdisk man page for more details.
