Hello all,
I've been researching Linux-HA for a bit now and have been thoroughly
impressed with the project. Thanks so much for contributing all of
this effort.
I have a few questions about a simple setup:
* Node 1 is an active webserver with static content
* Node 2 is a passive failover (synchronized through rsync)
* Machines have 2 NICs (public and private), heartbeat uses both
* No serial connection is possible in this datacenter
* Resources will be 1 virtual IP (using IPaddr2) and httpd
* There is *no* shared storage of any kind.
* Preference is for failback to Node 1 on recovery
Is STONITH of any importance in this setup? I think not, but wondered
what may happen if Node 1 goes AWOL and Node 2 takes over while Node 1
still has the virtual IP in use. Will the arping from Node2 preclude
anyone from talking to Node 1 anymore. Or will there be some
contention for the IP?
STONITH is desirable in that it might bring Node1 back. My worry is
that with a 2-node cluster like this, STONITH leads to both nodes
shooting each other.
Reading the docs and list archives has helped, but this is such a
simple case it doesn't show up in FAQs or on the list.
Best,
Brian Kirkbride
