Hi All,
I need an urgent help . i am planning to use suse 11 openais
cluster. i need to know one very basic question . how does it handle
data intigrity.
The same way heartbeat did (if you're familiar with that).
Check out the section on STONITH in the configuration explained
document (http://clusterlabs.org/wiki/Documentation)
i have seen some document on scsi2reservation
my understanding is that this is being used as a form of stonith
but that does not persist during node reboot. i have seen some
disussion that Persistent reservation (Scsi -3) is not available on
suse 11 but i am very much sure that there must be something you ppl
are using to protect your data and address data intigrity issue
during spilit brain.
also check out the no-quorum-policy setting that applies to split-brain
can any one tell me whats are the possible mechanism to protect
data in suse 11. Please do answer. this is very important for me .
i will have to take decision whether i should start using suse 11 or
not.
i am aware that RHCS has Persistent Reservation feature. due to some
reasons i cant use RHCS . i want to use suse11 .
please help me with this.
waiting for your reply,
Thanks
