It is recommend to look how the commands work.
A little overview:
Where are my Files?
If you want to know where you files are stored, try
fs exa <file/FID> .
You get an output like:
File <file> (<FID>) contained in volume <vid>
Volume status for vid = <vid> named <name of the vid>
So you know on which volume your files where stored.
Where are my Volumes?
With fs exa you the name and the volume ID, now you can type:
vos exa <volume Name/vid>
There you get a large output about the volume.
The last entry says:
- number of sites
Below you see where you volumes are stored.
How many OSD Server are on the site?
Thats a little list of all server with an entry in the osddb.
Instead of the name you can also use the ID of the server for further commands.
Can I see all volumes on one server?
Yes, you get all volumes on a server with
osd volumes <OSD name/OSD ID>
Thats only an list of volume numbers on the given OSD without further information.
