Hello, We are planning on expanding our storage by adding more OSTs to our lustre file system. It looks like it would be easier to expand if we bring the filesystem down and perform the necessary operations. We are planning to suspend all the jobs running on the cluster. We originally planned to add new OSTs to the live filesystem.
We are trying to determine the potential impact to the suspended jobs if we bring down the filesystem for the upgrade. One of the questions we have is what would happen to the suspended processes that hold an open file handle in the lustre file system when the filesystem is brought down for the upgrade? Will they recover from the client eviction? We do have vendor support and have engaged them. I wanted to ask the community and get some feedback. Thanks, -Raj
