Thank you for the response.

I'm Pretty sure the problem is with the Gluster's NFS and how XenServer interacts with it. As I feel like its not running in async mode. Everything is at-least 10x faster using bland kernel NFS with the async option... 90+MB/sec (saturate gigabit) vs 5~7MB/sec I'm pretty sure there is a default option in the gluster nfs that needs changing.

I tried the " nfs.trusted-sync off" option.
as well as the "tuned-adm profile rhgs-random-io " (which isn't aviable on cent btw)
and using the gluster group virt and the redhat options

Is there another way to ensure the Gluster NFS sync is in async mode?

Also currently following the Gluster and Centos guides GlusterFS and Ganesha isn't working.

I wish I could use oVirt but we can't sell oVirt to our customers :-/ (so we don't use/test), the User Interface is to confusing for them. Also many still have (alot :-( of ) Windows 7 VM's and its not as easy to do a windows image restore/deploy on oVirt (due to the drivers) , XenServer works better and is easier for the less tech inclined to use (Jr SysAdmins and the like). I really wish RedHat/oVirt would keep that current Industrial UI and build a second "iPhone user" friendly UI (like XenCenters simple refined UI, it gives some exec's confidence in the software, as some see oVirt and think of it as a 'ol MS product, similarly why they are leaving VMWare ) .

Hello Eddy,

during the Test 1 the Ovirt Cluster Mount the Storage as GlusterFS,

locks like this on the Ovirt Node.

10.2.9.135:vol01   3% /rhev/data-center/mnt/glusterSD/10.2.9.135:vol01

And I test the dd direct under the mount point directory, mean the test 1 is a pure glusterfs

performance test, and I can see with itraf-ng or nload the the ovirt node use 6 network
connections to put the data to the disperse volume.

In test 2 the the NFS to the mdadm raid 5 is simple centos7 nfs.

Betreff:  Working and up to date guide for ganesha ? nfs-ganesha gluster-ganesha

Hello,

I've tried all the guides I can find. The is alot of descrepency on the ganesha.conf file and how it interacts with gluster. none of the examples I found worked, also none of them have been updated in the last year or so, even Redhat's.

any one have a link to a working guide for ganesha? 

Also still looking for help with Gluster hosting VM images for Xenserver. The 6MB/sec best we've seen is sad. Bland NFS with async gives us 110 MB/sec . 

Thanks
