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

Wed May 20 08:09:41 EDT 2015

Hi Maor

Sorry for the late answer, I was out of office for a couple of days.

You were right, it was an engine issue. Never happened before, after attaching and detaching more than one time the export domain.

A restart solved the issue, the export domain that before the reboot was shown in "preparing for maintenance" , after reboot was shown in the correct state, so detach, reattach to another DC was tried successfully, at least three times, with export / import activity also.

Thank you so much !.
Best regards,

Roberto
