Re: Vm migration between diff clusters

Actually SSHFS works very well in a single user situation.

We have seen similar performance to NFS with it and of course it tunnels through firewalls a lot more easily, so its been our go to when live migrating among clusters, especially as we have a mix of shared storage and direct storage depending upon the need of the devs who use the various  systems.

That being said, if NFS is already there, then yes, a simple mount is easier than yum install fuse-ssh and then:


sshfs -o allow_other,compression=no $user@$remote_host:$remote_folder $mnt_folder

<Grin>

I just checked and on our older Gluster boxes, still on 3.4.

NFS is turned off, perhaps deliberately by the tech who installed it.

On the newer versions, I was under the impression that NFS was deprecated in favor of Ganesha?

Is that turned on by default?

GlusterFS comes with an NFS export by default, so there really isn't any
setup to do that, jut a simple mount -t nfs. It's even simpler than sshfs,
and I'm pretty sure the VM will work a lot better during the live migration
using nfs than sshfs :)
