Hi Khabou,

There are several interpretations to your question..

If you want to query the exact different physical locations of a file, you
can query the ring as follows.


*# find the account id for a given account
> #
> # $password  =  the general swift admin pass
> # $account  =  the account to which the file you're looking for belongs
> # (and change the host / port / protocol to match your setup)*



*swauth-list -A http://localhost:8080/auth/ -K $password $account*





*# Find location of files for a given object
> #
> # $id  =  the id retrieved through the command above
> # $container  =  the container in which the file resides
> # $file  =  the name of the file*



*swift-get-nodes /etc/swift/object.ring.gz $id $container $file*

*
*
*
*
This will tell you were the file matching the "/account/container/file"
path you provided will reside (giving both the primary + hand-off
locations).

It will do so regardless of whether that path (and thus file) actually
exists, since as soon as you have build the ring that information is static
/ known for every possible combination of
that "/account/container/file" path. (that may change if the ring gets
rebuild)


If this is not the answer to your question, please elaborate a little more
on what you want to achieve exactly.


Kind regards,
Frederik Van Hecke
