Ceph » CephFS

I wanted to test cephfs snapshots in latest Reef and noticed a discrepancy when it comes to time format, for example this works:

$ ceph fs snap-schedule add test-snap-dir1 1h
Schedule set for path test-snap-dir1

While minutes are not allowed, but only if you specify capital "M", otherwise it's not parsed:

$ ceph fs snap-schedule add test-snap-dir1 1m
Error ENOENT: schedule multiplier "m" not recognized

$ ceph fs snap-schedule add test-snap-dir2 2M
Error ENOENT: no minute snaps allowed

I would read capital "M" as "Month(s)", not "Minutes". Especially if one compares it with other schedules, e. g. rbd mirror:

$ rbd -p pool1 mirror snapshot schedule add 60m

Or the general 'ceph status' output for the uptime of daemons:

    mon: 3 daemons, quorum host3,host2,host1 (age 2d)
    mgr: host2(active, since 17m), standbys: host1, host3
    mds: 1/1 daemons up, 5 standby
    osd: 9 osds: 9 up (since 2d), 9 in (since 6M)

This is a little confusing and should be the consistent across all entities using time formats.
