mounted.ocfs2 - Detects all OCFS2
volumes on a system.
is used to detect OCFS2
volume(s) on a system. When
run without specifying a device
, it scans all the partitions listed in
- Lists the OCFS2 volumes along with their labels and
uuids. It also lists the cluster stack, cluster name and the cluster
flags. The possible cluster stacks are o2cb, pcmk and
cman. None indicates a local mount or a non-clustered
volume. A G cluster flag indicates global-heartbeat for the
o2cb cluster stack.
- Lists the OCFS2 volumes along with the list of nodes
that have mounted the volume.
As this utility gathers information without taking any cluster locks, the
information listed in the full detect mode could be stale. This is only
problematic for volumes that were not cleanly umounted by the last node. Such
volumes will show up mounted (as per this utility) on one or more nodes but
are in fact not mounted on any node. Such volumes are awaiting slot-recovery
which is auto-performed on the next mount (or file system check).
