Hi all,
One server Redhat 6 with this rpms set:
[ ~]# rpm -qa | grep gluster | sort
glusterfs-3.5.2-1.el6.x86_64
glusterfs-api-3.5.2-1.el6.x86_64
glusterfs-cli-3.5.2-1.el6.x86_64
glusterfs-fuse-3.5.2-1.el6.x86_64
glusterfs-geo-replication-3.5.2-1.el6.x86_64
glusterfs-libs-3.5.2-1.el6.x86_64
glusterfs-server-3.5.2-1.el6.x86_64
I have a gluster volume with 1 server and 1 brick:
[ ~]# gluster volume info volume-nova-pp
Volume Name: volume-nova-pp

Bricks:
Brick1: 192.168.61.100:/brick-nova-pp/mpathc

There are four clients attached to this volume with same O.S. and same
fuse gluster rpms set:
[ ~]# rpm -qa | grep gluster | sort
glusterfs-3.5.0-2.el6.x86_64
glusterfs-api-3.5.0-2.el6.x86_64
glusterfs-fuse-3.5.0-2.el6.x86_64
glusterfs-libs-3.5.0-2.el6.x86_6
Last week, but it happens also two weeks ago, I found the disk almost
full and I found the gluster logs
/var/log/glusterfs/var-lib-nova-instances.log of 68GB:
In the log there was the starting problem:
[2014-10-10 07:29:43.730792] W [socket.c:522:__socket_rwv] 0-glusterfs:

and a lot of these lines:
[2014-10-15 14:41:15.895105] W [fuse-bridge.c:2201:fuse_writev_cbk]
0-glusterfs-fuse: 951700230: WRITE => -1 (Transport endpoint is not

[2014-10-15 14:41:15.896205] W [fuse-bridge.c:2201:fuse_writev_cbk]
0-glusterfs-fuse: 951700232: WRITE => -1 (Transport endpoint is not
connected)
This second line log with different "sector" number has been written
every millisecond so in about 1 minute we have 1GB write in O.S. disk.
I search for a solution but I didn't find nobody having the same problem.
I think there was a network problem but why does gluster write in logs
million of:
[2014-10-15 14:41:15.895105] W [fuse-bridge.c:2201:fuse_writev_cbk]
0-glusterfs-fuse: 951700230: WRITE => -1 (Transport endpoint is not
connected) ?
Thanks in advance.
Cheers
Sergio
