Hi,
I have a cluster of 2 servers running 3.7.3 with replication, and standard
NFS (no ganesha). This in on CentOS 6.
I use CTDB with 2 virtual IPs (one for each server in a normal
situation) to share the volume over NFS and CIFS (samba).
fnctl() file locking doesn't seem to work when the
Sorry only read replicated in your first mail, I squashed the distributed
one :'(

As you are in replicate mode, all write will be send synchronously to all
bricks, and in your case to a single hdd.
I thought that every file will be sent to 2 bricks synchronously but if
I write several files they are distributed between the three pairs of
bricks. Therefore the performance
In my current configuration I have a distributed and replicated volume
which is (to my understanding) similar to a raid 10.

In this scheme, you wouldn't much more than 3 bricks.
I think you mox up with distributed scheme, which is like a raid 0 stripped.

There is no 3.7 client for precise. The build is 'all or nothing'.
3.6 for precise ought to work with 3.7 servers. Try it and see.
It would be great if someone in the community wanted to step up and

Hi Vijay,
du command can round-off the values, could you check the values with 'du -sk’?
It’s ongoing. I’ll let you know the new value ASAP.
We will investigate on this issue and update you soon on the same.
FYI it’s mainly concerning 1 brick per replicate (and thus its replicate brick:

Hi all,
I'm back and tested those things.
Michael was right. I've enabled read-ahead option and nothing changed.
So the thing causes the problem with libgfapi and d8 virtio drivers

set it On, different problems are as result

FWIW, this is a rather old release. Can you see if the issue is
recurring with glusterfs 3.7?

Hi Ravi,
Not easily: 3.2.5 is what comes with Ubuntu 12.04 and based on previous posts
on this list it seems I can't just go and compile a newer one.
If our setup should work and an upgrade might fix the issues we see, then we
could try Ubuntu 14.04 - it's not a supported environment in our
Thanks, Ravi - I was not aware of that.
I'll update and try again.

Hello,
We are trying to run a pair of ActiveMQ nodes on top of glusterfs, using the
approach described in

This seemed to work at first, but if I start rebooting machines while under
load I seem to quickly get into this problem:

Creating data from back end is definitely not recommended as features like
replication heavily depends on the external attributes set on the file and
having data created directly from back end wouldn't have the xattrs set.

There is no restful api support in gluster to manage your cluster. Yet that
