Hello
I have 3 servers and 1 server (client)
3 servers having /data folder with size 300Gb
Can you tell me the best combination to create volume?
gluster volume create my_volume replica 3 transport tcp node1:/data node2:/data
node3:/data
is this ok for best performance ?
Thx
Hello
I create volume with next command:
gluster volume create opennebula replica 3 transport tcp node1:/data
node2:/data node3:/data
# gluster volume info
Volume Name: opennebula
Type: Replicate
Status: Started
Number of Bricks: 3
Transport-type: tcp
Bricks:
Brick1: node1:/data
Brick2:
seems issue was in
auth.allow: 176.126.164.0/22
hmmm... client and nodes was from this subnet.. any way .. I
recreated volume and now everything looks good
thx

Hello, again
Smth wrong with my install gluster
OS:Debian
cat /etc/debian_version 7.6
Package: glusterfs-server
Versions:
3.2.7-3+deb7u1

node1,192.168.1.2 - node2, 192.168.1.3 - node3)

if do not want use rsync, you may use lsyncd - i'm using lsyncd to
sync in realtime two nodes

I do not think that isssue with network
I have just tested mount -t nfs gluster:/volume /mnt
and read speed very high on small files:
for example:
Write
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 0.0357166 s, 573 kB/s
read
10+0 records in
10+0 records out
20480 bytes (20 kB)
Hello, sorry for delays with anwers
I have 1Gb network based on Intel(R) PRO/1000 Pci-E cards
I'm waiting Intel(R) PRO/1000 2 Gb Ports cards PCI-e..
I suggest trying larger block sizes and higher I/O thread count
Should I make some tweaks on GlusterNodes (peer) and client ? Can you
give me a
root@ispcp:~# mount -vv -t nfs -overs=3 192.168.15.165:/storage /storage
mount.nfs: Unknown error 521
root@ispcp:~#
root@ispcp:~# mount.nfs -v -overs=3 192.168.15.165:/storage /storage
mount.nfs: Unknown error 521
root@ispcp:~#
please note that :
apt-cache showpkg nfs-client
Package: nfs-client
sorry it was my mistake
/storage was already mounted by glusterfs
Thank you for your help

Hello, guys
I wrote small script :
#!/bin/bash
for i in {1..1000}; do
size=$((RANDOM%5+1))
dd if=/dev/zero of=/storage/test/bigfile${i} count=1024 bs=${size}k
done
This script creates files with different size on volume
here is output:
2097152 bytes (2.1 MB) copied, 0.120632 s, 17.4 MB/s
of example same client wrote file to nfs share
root@ispcp:/mnt# dd if=/dev/zero of=./bigfile${i} count=1024 bs=10k
1024+0 records in
1024+0 records out
10485760 bytes (10 MB) copied, 0.133489 s, 78.6 MB/s
much faster :(
cat /etc/mtab
