Description of problem:
Currently NFS storage domains are mounted with soft mount. Although there is no technical issue with it, hard mounts are much more common hence tested better so it's preferable to support hard mounts.
To prevent vdsm from hanging support should be for hard,intr and have mechanisms to interrupt I/O in the control path after a timeout

is this still relevant with all the time we are with soft mounts?

It will always be relevant regardless of the current way being 100% ok.
1. With NFS people prefer their VM not pausing on EIO but hanging the I/O.
2. Perception wise people prefer hard mounts
On the flip side, changing everything to work with hard mounts might be challenging due to the need to detect hangs and interrupt processes such as dd (in the control path)
don't remember anyone asking about this for a while. its making things complex for the spm/sdm data operations. we work correctly and robustly with soft mounts
