[ovirt-users] activation of iso domain

[Darren Hart]

Hi,

Was wondering if anyone has any ideas about what might be preventing my iso domain from attaching to my data centre ? The iso domain was working correctly prior to a system restart but is now kicking up an error when I try to attach it :

I’m running a hosted engine install and the NFS export for the iso domain is also the single host in the cluster. I have tried deleting the iso domain and using an NFS share on a different server to create a new one but it fails with the same error message. The NFS export has been tested good in both cases, and can be mounted from the hosted engine VM directly if I SSH in and mount. The directory has 36:36 permissions and the vdsm user has rw ability with the share manually mounted in the hosted-engine vm.

On the hosted-engine box I have also downloaded the nfs testing python script and run it against the currently configured nfs share and it returns a OK result.

Executing NFS tests..
Removing vdsmTest file..
Status of tests [OK]
Disconnecting from NFS Server..
Done!

I’m a bit stumped as it was working great prior to the restart so not sure what might have changed in the process. Selinux is disabled on both the servers I’ve attempted to use as NFS shares for the domain.

The data domains are working and one of these is an NFS share to the same server as the iso domain.

Anyone have any avenues they can steer me down to where the problem may lie or am I missing something obvious ?
