Hi,

We're having problems mounting the preexisting 3.12 glusterfs storage domains in ovirt node ng 4.3.0 rc2.

Getting

There are no iptables blocks on the storage network, the ip's are pingable bothe ways. I can telnet to the glusterfs ports and I see no messages in the logs of the glusterfs servers.

When I try the mount command manually it hangs for ever:

/usr/bin/mount -t glusterfs -o backup-volfile-servers=*.*.*.*:*.*.*.* *.*.*.*:/sdd8 /mnt/temp

I haven't submitted a bug yet....
