Gluster users - Nov 2017 - What is the difference between FORGET and UNLINK fops

Hi,

Can I get a brief description of all the FOPS in gluster or the location of
the source code file so that I will try to get an understanding myself?

Few FOPS I'm not clear like FORGET, UNLINK, FLUSH, LOOKUP


Or is there a way I can tunnel through the FOPS that that are happening in
the background for each operation? I have tried this to find from a brick
logfile in TRACE mode, but there are way too many calls, but are in form of
some system calls but not FOPS.

Regards,
Jeevan.

Filtering the brick logs in TRACE mode with rpcsvc.c does show the FOPS.

actually
differs from NFS lookup operation. Please correct me if I'm wrong.

Jeevan.

Here is some of the ones we collected:

https://github.com/bengland2/gluster-profile-analysis

It doesn't have some of the ones you are looking for but if you get
definitions of what they are I would like to add them to what we have in the
profile analysis tool's README.

HTH!
