[ovirt-users] Master Storage Domain fails to activate

[Nathan Llaneza]

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.
