Hey Liron,

I have attached the logs from two of the hypervisors. After I reboot the hypervisors it seems as if I can access the storage volume at /rhev/data-center/mnt/172.16.241.99:_mnt_storage/; however it only last for a minute of so before I get a "Input/output error". On the NFS server itself I can browse through the directories just fine. I am starting to suspect that this is a CentOS 7/NFS issue... When I mount the nfs share from the engine it works perfectly. As a note my hypervisors are CentOS 7 x64 and my engine is CentOS 6.6.

Hi Nathan,
please attach also the vdsm logs from the hosts.
also, please check the storage access from the hosts and what's under the domain dirs - for example the domain under 172.16.241.98:/mnt/storage
