<p>Amjad,</p>
<p>That would depend on how they setup PCS. If you are going to have
a 'floating' IP that is failed over and merely used for the login
traffic, there should be no issue.<br>
</p>
<p>I think the method for HA is a bit overkill, however. Depending
on what services are running, it may make more sense to just have
a secondary system that is running and use DNS to failover or just
round-robin users to balance them across the systems that are up.
Certainly easier to maintain and easier to recover when something
happens.<br>

<div dir="ltr">Hello,
<div>We have a small 10 node compute cluster . We have single
management/head node which is used as login node as well. The
management consider this head node as single point of
failure. They are planning to buy another
head/login/management node and make an active-passive cluster
using Red hat pcs. The question i have is the Lustre file
system which is mounted on these two nodes , will it be
effected when the transfer between two nodes happen. </div>
