Hi all,
Now I try glusterfs 3.6.0, use the same configuration to do test. But the
situation has not improved, several hours later, bricks' log still says "socket
disconnection".
I doubt this problem may be caused by epoll, so I patch system using
"http://review.gluster.org/#/c/3842/13//COMMIT_MSG";, but it seems do
not work.

Hi everyone,
I am trying to run multipal jobs using fio benchamark in replica volume
with 3 bricks, but some hours later, warning message “W
[socket.c:195:__socket_rwv]
0-tcp.ida-server: readv failed (Connection timed out)” appear in bricks logs, I
think this
waring may due to high work loads, glusterfs with high work loads can not
respond
socket timely. So I add codes in rpc/rpc-transport/socket/src/socket.c to
expand timeout
threshold of socket, now the SO_RCVTIMEO is 180s, KEEP_ALIVE is 300s, then run
work load again, but it does not work.
My test enviroment is as follow:
Three nodes work as gluster cluster, each nodes with 16GB memory, 8 core
3.3GHz cpu， two 10000baseT/full and one 1000baseT/full network cards, each nodes
use 16 * 2T raid5 disks working as brick. The glusterfs version is 3.3.1.
Just wanted to know if there is a possibility of using newer versions. No new
releases are being made from 3.3.x. Could you try the case on newer versions
and let us know your findings? If for some reasons you can't upgrade then we
can probably start debugging this in 3.3.x. But I highly recommend you use a
version that is active i.e. at least 3.4.x

I create a 1*3 replica volume use this three nodes, every node use fuse to
mount
volume through a 10000baseT/full network card. At the sametime, every node use
cifs to
mount fuse_mount_point through another 10000baseT/full card.
Each node run two fio scripts, read and write jobs. Both scripts do
operation in
cifs_mount_point. scripts is as follows:
write_jobs:
while true
do
mkdir -p ${DIR}_write_${i}
/usr/local/bin/fio --ioengine=libaio --iodepth=256 --numjobs=100 --rw=write
--bs=1k --size=1000m --directory=${DIR}_write_${i} --name=job01_1k_write >>
${DIR}_write_${i}/job01_1k_write.log
i=`expr $i + 1`
done
read jobs:
mkdir -p ${DIR}_read_${i}
/usr/local/bin/fio --ioengine=libaio --iodepth=256 --numjobs=100 --rw=read
--bs=1k --size=1000m --directory=${DIR}_read_${i} --name=job01_1k_read >>
${DIR}_read_${i}/job01_1k_read.log
i=`expr $i + 1`
done
I change iodepth from 256 to 16, numjobs from 100 to 25, but it still does
not
work. Is there anybody pay attention to this problem?
