Pranith,

                 Thanks for getting back on this. I am trying to see how gfid can be generated programmatically. Given a file name how do we generate gfid for it. I was reading some of the email threads about it where it was mentioned that gfid is generated based upon parent directory gfid and the file name. Given a same parent gfid and file name do we always end up with the same gfid.

No, gfid is a UUID, so there is correlation. https://en.wikipedia.org/wiki/Universally_unique_identifier can help you I guess. Where did you see the above information that Parent gfid and name are involved?

PS: These kinds of mails people in gluster-devel are more suited to answer IMO.

 

Thanks and Regards,

ram

Sorry, didn't understand the question. Are you saying give a file on gluster how to get gfid of the file?

#getfattr -d -m. -e hex /path/to/file shows it

Hi,

        Is the mapping from file name to gfid an idempotent operation.  If so please point me to the function that does this.

 

Thanks and Regards,
