Yes. FUSE does support it in recent kernels (3.4), and I tried it.

HI,
Is there a way to get good performance when an application does small
writes?
Most of the apllications using NetCDF write big files (upto 100GB) but
using small block-sized writes(Block size less than 1KB)
Hi Pranith;
Thanks for your reply.
I checked md5sum too, it is different.

Folks,
Gluster is not ready to run Virtual Machines at all. Yes you can build a 2 node
cluster and live migrate machines, but the performance is poor and they need to
do a lot of work on it yet.
I wouldn't put in production even a cluster with low performance web server VMs

If I'm reading them correctly, the normal fuse mount performance
is about what I was seeing, 2-3MB. And now bypassing everything,
libglusterfs is still capping out a little under 20MB/s.
It's

OK. Then that's the client I was talking about.

No, I meant writethrough. Initially I had just done dd

Hi Harry,
Running Gluster-3.3 on Redhat 6.2 with the RPMs provided by gluster.org.
I rpm -e previous gluster install, it could be possible that it's picking
up older files.
I did find in the entire system with '*gluster*' and cleaned those out.
So, it's a bit weird to me.

I was using the ISO from Oracle and it's booting Oracle Unbreakable Kernel

Switching to upstream Redhat Kernel fixed the issue.

Hello everybody,
I would export thought NFS, or evently native glusterFs, some directories from
a volume but I need that each directory should be only exported to a specific
IP address.
As an exemple :
/data1 would be exported only to 10.0.0.1
/data2 would be exported only to 10.0.0.2
/dataX
21 matches
