The retry() calls wrapping self.con.exec_cmd() were broken in two ways: 1. exec_cmd was called immediately and its tuple result passed to retry() instead of passing a callable, so no retry ever occurred 2. Connection.exec_cmd() returns (retcode, stdout, stderr) and never raises CommandFailed, so the retry exception type never triggered Add _mount_nfs_with_retry() helper that wraps exec_cmd in a nested function which raises CommandFailed on non-zero retcode, and calls it via retry properly. Replace all 5 broken call sites. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Signed-off-by: Amrita Mahapatra <49347640+amr1ta@users.noreply.github.com>
IBM Cloud VPC LoadBalancer security groups block inbound traffic by default. The NFS LB on port 2049 needs an explicit inbound rule, same as the ingress LB needs rules for ports 80/443 (added in red-hat-storage#15012). Add configure_nfs_lb_security_group() that finds the VPC LB backing the rook-ceph-nfs-my-nfs-load-balancer Service and adds an inbound TCP 2049 rule to its security groups. Call it automatically from create_nfs_load_balancer_service() on IBM Cloud. Add remove_nfs_lb_security_group_rules() to clean up the rule during teardown, called from delete_nfs_load_balancer_service() before the Service is deleted (so the VPC LB is still present for lookup).

Assert that the specific subvolume created by the test is no longer stale after deletion, instead of asserting zero stale subvolumes cluster-wide. Pre-existing stale subvolumes from other tests caused false failures. Also log the delete output and stale lists for debuggability.
