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

[Diego Zuccato]

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...
