…#18118) The NFS mount in test_main_prep_node.sh can fail with "access denied" when the NFS server on FIRST_NODE hasn't fully registered its exports before client nodes attempt to mount. This is a race between setup_nfs.sh completing on the server and clush launching test_main_prep_node.sh on all nodes simultaneously. Add a retry loop (3 attempts, 5s apart) around the mount call, and on final failure print showmount/getent diagnostics to aid debugging. Also tighten the /proc/mounts grep to avoid false substring matches. Signed-off-by: Ryon Jensen <ryon.jensen@hpe.com>

There was a problem hiding this comment.
We will probably want to use a global "retry" function in the future like we do for post provisioning, but we can optimize later...
