Hello, 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.
