Hi,

 

I’ve done some testing and it turns out that my NFS-Server seems to be the limiting factor in combination with the used NFS version. The Server is a Windows Server 2012 R2 with “Service for Network File System” installed. I mounted the share from ovrit with the default nfs version 3 and it work but not more than 100Mbit/s and I don’t know why. When mounting the share on the host manually like so “mount –t nfs4 –o minorversion=1 172.16.6.7:/test /mnt/test/” I was able to get to about 400Mbit/s. It’s still far away from full speed  but that’s ok for me. I tried to change the NFS version in ovirt to V4, but with these settings the mount fails. It has to be NFS4.1 – can that be done over the GUI somehow or are there any other options ?

 

Thank you,

 

Sven

Not true, we have seen significant slowness because of the way oVirt exports the VMs, as well as I/O.

 

Well all I wanted to say with this is, that there is no artificial limitation of the speed. At least not that I know of, if there’s an issue with the speed which is caused by a software issue on our side please do report a bug.

Hi Everyone, 

 

I’m trying to export VMs to an Export Domain for Backup and noticed that all of this is running at max 100Mbit/s. Is this some limitation that comes with the Export Domain ? I’ve checked all network connections and all of them report at least 1000Mbits/s.  Am I missing something ? 

 

So from our side there’s no limitation. So there might be a router, switch or anything in between that does not support 1 GBit on your network. You’re really just limited here by Storage and/or Network bandwith.

 

Thank you, 

 

Sven
