Hi Martin,
Yes...I want to know the timeout after the host will be considered non
responsive and fencing will be executed on it ?? can it be modify ?? if
yes...please suggest me know the way to do this ??
Please take a look at calculation in
http://www.ovirt.org/Automatic_Fencing#Automatic_Fencing
Host status will to Non Responding if either number of unsuccessful
connection attempts exceeds VDSAttemptsToResetCount or timeout from
last successful connection is expired.
To alter time for host to be fence you can change these values from above
mentioned calculation can be changed using engine-config tool:
VDSAttemptsToResetCount
TimeoutToResetVdsInSeconds
DelayResetPerVmInSeconds
DelayResetForSpmInSeconds
Is there any specific issue for which you need to change those values?
Martin
Thanks,
Punit
