It is advisable to create a ZFS snapshot, to be sure that there are some
checkpoint state:

    # zfs snap storage@snap1
    $ cd /storage/.zfs/snapshot/snap1

Run the index procedure:

    $ glocate -db /tmp/db -index

After that, you can print all filenames:

    $ glocate -db /tmp/db

List them with sizes and mtimes in machine parseable format:

    $ glocate -db /tmp/db -machine

Or in human-friendly tree-like format:

    $ glocate -db /tmp/db -tree

You can limit the hierarchy with the -root:

    $ glocate -db /tmp/db -root music
    [just a music]

And you can specify glob pattern for case-insensitive match for each
element path, that is automatically wrapped with "*":

    $ glocate -db /tmp/db -root music blasphemy | grep "/$"
    music/Blasphemy-2001-Gods_Of_War_+_Blood_Upon_The_Altar/
    music/Cryptopsy-1994-Blasphemy_Made_Flesh/
    music/Infernal_Blasphemy-2005-Unleashed/
    music/Ravenous-Assembled_In_Blasphemy/
    music/Sect_Of_Execration-2002-Baptized_Through_Blasphemy/
    music/Spectral_Blasphemy-2012-Blasphmemial_Catastrophic/

If you changed you dataset(s) somehow, then you should create new
snapshot and feed its diff to the command:

    # zfs snap storage@snap2
    # zfs diff -FH storage@snap2 |
      glocate -db /tmp/db -update /storage/

Argument to -update is the prefix stripped from each filename of
diff's output.
