s1pm1: not manage the filesystem.
s1pm1: 2 - external *. If you have other mountable filesystems you would
s1pm1: like ColumnStore to use & manage, select this option.
s1pm1: 3 - GlusterFS * Note: glusterd service must be running and enabled on
s1pm1: all PMs.
s1pm1: 4 - S3-compatible cloud storage *. Note: that should be configured
s1pm1: before running postConfigure (see storagemanager.cnf)
s1pm1: * - This option enables data replication and server failover in a
s1pm1: multi-node configuration.
