Gluster users - Dec 2017 - What does gluster do when it's idle?

Hi,

There's no client activity and I have collected tcpdump for 5 mins on one
of the glusterFs sever which is also a client with gluster NFS mount. From
tcpdump I see that for every few seconds, STAT & STATFS commands are run.
For whichctory are these commands being run and why?

Regards,
Jeevan.

Hi,

Also I forgot to mention there are DUMP and PORTBYBRICK calls too. I
understood these too calls are to get updated on gluster configuration.

But all these two calls are to a particular node only while there are total
(2+1)*3= 6 nodes in my configuration. Why so? What exactly is DUMP and
PORTBYBRICK?

Regards
Jeevan.

Hi,

Okay I've understood what's going on. There's a monitoring service
running
for NFS mounts and those are causing the STAT and STATFS calls I found this
by checking the uid shown i  the rpc credentials section.
