node.
# mount | grep zdata
zdata on /zdata type zfs (rw,nosuid,noexec,noatime,xattr,noacl)
zdata/cicd on /zdata/cicd type zfs (rw,nosuid,noexec,noatime,xattr,posixacl)
Then I mounted glusterfs locally and local changes started to go to Slave node
too.

I have two clusters with dispersed volumes (2+1) with GEO replication
It works fine till I use glusterfs-fuse, but as even one file written over
nfs-ganesha replication goes to Fault and recovers after I remove this file
(sometimes after stop/start)
I think nfs-hanesha writes file in some way
Hi,
Could you help me?
i have a problem with file on disperse volume. When i try to read this from
mount point i recieve error,
# md5sum /mnt/glfs/vmfs/slake-test-bck-m1-d1.qcow2
md5sum: /mnt/glfs/vmfs/slake-test-bck-m1-d1.qcow2: Input/output error
Configuration and status of volume is:
Hi, community
Please, help me with my trouble.
I have 2 Gluster nodes, with 2 bricks on each.
Configuration:
Node1 brick1 replicated on Node0 brick0
Node0 brick1 replicated on Node1 brick0
Volume Name: gm0
Type: Distributed-Replicate
Volume ID: 5e55f511-8a50-46e4-aa2f-5d4f73c859cf
Status:
Hi, community
I have a large distributed-replicated Glusterfs volume, that contains
few hundreds VM's images. Between servers 20Gb/sec link.
When I start some operations like healing or removing, storage
performance becomes too low for a few days and server load becomes like
this:

Hello everybody,
Please, help to fix me a problem.
I have a distributed-replicated volume between two servers. On each
server I have 2 RAID-10 arrays, that replicated between servers.
Brick gl1:/mnt/brick1/gm0 49153 0 Y

Brick gl0:/mnt/brick0/gm0
undergoing heal

Despite on the quorum is turned on sometimes we are still encounter a
split-brain occurrence after shutting down one node or all nodes together/
Is this is a normal behavior? What conditions could lead to this and how to
prevent split-brain occurence?

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

Versions:

Yes, Roman is correct. Also, if you have lots of random IO you're better
off with many smaller SAS drives. This is because the greater number of
spindles you have the greater your random IO is. This is also why we went
with ssd drives because sas drives weren't cutting it on the random io
Hi Ryan,
I think if you could provide more info on the storage systems it would
help. Things like total drives per raid set and size of each drive. This
is a complicated question, but a simple Googling brings up this
interesting article:

Hi All,
I'm having a horrid time getting gluster to create a volume. Initially,
I messed up a path and had the error mentioned here:
http://joejulian.name/blog/glusterfs-path-or-a-prefix-of-it-is-already-part-of-a-volume/
I fixed it, restarted gluster on both nodes, and then I just get a

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.nfs -v -overs=3 192.168.15.165:/storage /storage

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 :(
