The LSO code path used ceph_daemon_id label to find the mon pod, but this label is shared between mon and mgr pods (both have ceph_daemon_id=a). When the mgr pod was returned first by the API, the test selected it instead of the mon pod, causing mon_suffix=None and mkdir failure. Replace the LSO-specific pod lookup with get_mon_pods() which uses the unambiguous app=rook-ceph-mon label. The worker node for the LSO dd path is now derived from the selected mon pod's spec.nodeName.

On LSO, df -Th | grep /etc/hosts returned empty because df shows mount
points not file paths, causing IndexError. Use df -Th with the actual
mon data path (/var/lib/rook/mon-{suffix}/data) via oc debug on the
worker node. Also switch non-LSO to use df -Th {path} directly instead
of grep for reliability.

Writing 1GB of random data via oc debug can exceed the default 300s timeout, especially on later iterations when the disk is nearly full. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Signed-off-by: Amrita Mahapatra <49347640+amr1ta@users.noreply.github.com>
