[Gluster-users] Interpreting gluster volume top read/write output
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

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...
