[ovirt-users] R: NFS export domain still remain in "Preparing for maintenance"

[NUNIN Roberto]

Hi Maor

Thanks for answering.

Probably my description wasn't so clear, try to explain better.

We have configured one storage as NFS export (exported from a server that isn't part of the oVirt installation), to be used to move exported VM between one DC and another.

The process to export VM's ends correctly but, when we try to put the NFS export storage in maintenance mode (not the hosts) before to deattach it from the current DC and, subsequently, attach to the DC where I want to import VM, the process remain hung  indefinitely in “Preparing for maintenance phase".

I'm sure that the VM export process is ended correctly, looking at the logs in the engine GUI and also to data into the NFS export.

Because of only one export storage is allowed per DC, I'm not able to move VM between DC's.

This is the behavior.

Best regards


Roberto
