[Gluster-users] Debian Jessie (8) qemu-kvm VM and glusterfs as backend storage

[Roman]

Yes, I think it is networking related also.
I've tested with ping -f -s 1000 - no losses, but it seems to me, that D8
loses it's connectivity due to some reason. Maybe driver, May be something
else, not the line between servers as I just got the same problem on the
network of 2 switches (the problem I described above appears at the range
of 14 km, but it is only 0,1 ms further, than LAN :) 0,1 ms vs 0,2 ms.
Seems like D8 network driver has changed. Well, I think there is no way to
debug it on acceptable level for Debian guys, so I will wait for 8.1 or
even 8.2. Its too raw anyways. Thanks for your idea.
