THANK YOU!
Hi Chris, your mail almost got lost in another thread :)
Now I'm really confused. This option is on the server side.
Presumably when the client is started it already knows where the file
is due to -f on the client side. I don't understand.
Its used by '-s' option of glusterfs client for getting the specification
file from server.
The client configuration can be pulled in through two different ways:
1) through a local config file specified by -f
OR....
2) pulled in through the servers copy.
If you pull it in through the server then you don't need to distribute a new
client file to every client every time its modified (when the client
re-mounts, it will request the config file again from the server and get the
updated one).
It also means that every client will have a compatable config file. I.e. if a
volume is ment to be for a union, then all the clients will use it as a union
if they get there spec files from the server. However, a client *may* try to
use half of the union directly. This will not be an ERROR in the strict sense
of the word, but that client will now be violating the union filesystem
policy.
Hope this clears up some confusions (and doesn't add to it :)
Matt.
