Dear Xavier,
I realized that the volume was not build properly when doing the first
analyses suggested by Davide, but I'm sure that this is not the problem and
so I quickly dismissed it. Also, we need a replica but not so strictly,
maybe in the future with the next volume I'll build it properly. Anyway,
yes, the volume got birth on "pedrillo" with a replica-2 and the next day
was expanded on "osmino", again with replica-2, just by adding bricks and
doing a rebalance, that was just tried. I'm saying "tried" because it got
"stuck", consuming a lot of RAM (almost all, 16 GB), and it was counting
million of files that I think don't even exist on the volume, so I stopped
it. Do you think that it might be worth restarting?
The brick logs are there, just before your nice reply asking for them.
They're all the same, except for the order of the connection, all seem very
good.
Yes, you're right, many files are missing through the mounpoint, I just
choose one. But then again, what do you think about the fact that ls hides
them but calling them from the mount point are not counted as "file not
found"? "leggi_particelle" was working calling it from the bricks and from
the mountpoint, even if ls didn't show it in the mountpoint...
And here it is all the other info that you were asking: first of all a
collection of ls of the folder on all the bricks of the volume (10)

Something is not consistent here and I can see it by myself...
I hope to be forgiven for all these details and spamming in the mailing
list. I'm just arrived and I'm already filling it up... Sorry. But also
thanks a lot for your help!
