Re: Interpreting gluster volume top read/write output

Hi Hubert.

Didn't notice the 'top' command, so I cannot answer your doubts.

But I tried and noticed that read reports some entries like
2880            <gfid:dd539c92-ea64-4a96-b953-3a2d673496db>
2761            <gfid:eac8592f-63d0-4bb2-bdd8-92606d9c06a3>
Hope that's not symptom of a problem...

Hello @ll,

we're just doing some "research" on our own replica 3 volume
(hostnames gserver1-3, gluster 9.4), and there are a few questions
regarding the output of 'gluster volume top $volname read/write'.

1)
gluster volume top workdata write
Brick: gserver2:/gluster/md7/workdata
Count           filename
=======================
203             /images/504/013/50401355/de.mp4
195             /images/396/910/39691058/de.mp4
167             /themes/oad-high-scardus-trail/media/220202Hstimageslider1.mp4

does this mean that these files have been written 203/195/... times?
lifetime writes?

2)
gluster volume top workdata read
Brick: gserver1:/gluster/md3/workdata
Count           filename
=======================
1794            /images/441/297/44129755/de.mp4
275             /images/275/806/27580686/default.jpg
258             /images/269/844/26984442/default.jpg
256             /images/269/845/26984597/default.jpg

gserver1 was rebooted yesterday; does this mean these files have been
read 1794/275/... times? lifetime reads or since reboot?

We're just a bit ... curious if these are real read/write stats,
lifetime, since reboot.


thx,
Hubert
