4:32 p.m.
Hello List,
i set up a Cluster with 2 Nodes and Glusterfs.
gluster> volume info all
Volume Name: Repl2
Type: Replicate
Volume ID: 8af9b282-8b60-4d71-a0fd-9116b8fdcca7
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: node1.local:/data
Brick2: node2.local:/data
Options Reconfigured:
auth.allow: *
user.cifs: enable
nfs.disable: off
I turned node2 off. Just to make sure i have not network bottle neck and
that it will not replicate for my first benchmarks.
My first test with bonnie on my local raw disk of node1 gave me 130MB/sec
write speed.
Then i did the same test on my cluster dir /data: 130MB/sec
Then i did the write test in a freshly installed Debian 7 vm: 10MB/sec
This is terrible and i wonder why?!
My tests where made with:
bonnie++ -u root -s <double mem) -d <dir>
Here are my bonnie results: http://oi62.tinypic.com/20aara0.jpg
Since node2 is turned off, this cant be a network bottle neck.
Any ideas?
Thanks,
Mario

anyone?

Have you turned on "Optimize for Virt Store" for the gluster volume?

Yes, the only thing which brings the wirte I/O almost on my Host Level is
by enabling viodiskcache = writeback.
As far as i can tell this is caching enabled for the guest and the host
which is critical if sudden power loss happens.
Can i turn this is on if i have a BBU in my Host System?

I was referring to the set of gluster volume tunables in [1]. These
options can be enabled through "volume set" interface in gluster CLI.
The quorum options are used for providing tolerance against split-brains
and the remaining ones are recommended normally for performance.

Hi Vijay,
i deleted the Cluster/Datacenter and set it up with two new (physical)
Hosts and now the performance looks great.
I dunno what i did wrong. Thanks a lot....
