[ovirt-users] Hosted Engine/NFS Troubles

[Phillip Bailey]

Hi,

I'm having trouble with my hosted engine setup (v4.0) and could use some
help. The problem I'm having is that whenever I try to add additional hosts
to the setup via webadmin, the operation fails due to storage-related
issues.

webadmin shows the following error messages:

"Host <host name> cannot access the Storage Domain(s) hosted_storage
attached to the Data Center Default. Setting Host state to Non-Operational.
Failed to connect Host ovirt-node-1 to Storage Pool Default"


The VDSM log from the host shows the following error message:

"Thread-18::ERROR::2017-07-17 13:01:11,483::sdc::146::
Storage.StorageDomainCache::(_findDomain) domain
ca044720-e5cf-40a8-8b21-57a17026db7c
not found
Traceback (most recent call last):
  File "/usr/share/vdsm/storage/sdc.py", line 144, in _findDomain
    dom = findMethod(sdUUID)
  File "/usr/share/vdsm/storage/sdc.py", line 174, in _findUnfetchedDomain
    raise se.StorageDomainDoesNotExist(sdUUID)
StorageDomainDoesNotExist: Storage domain does not exist:
(u'ca044720-e5cf-40a8-8b21-57a17026db7c',)"


The engine log shows the following error messages:

"2017-07-17 18:32:11,409 ERROR
[org.ovirt.engine.core.vdsbroker.irsbroker.IrsProxyData]

[] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message:
Host ovirt-node-1 reports about one of the Active Storage Domains as
Problematic."


I have ownership set to vdsm/kvm and full rwx rights enabled on both
directories. I have successfully mounted both the master domain and the
hosted_storage manually on one of the hosts I'm trying to add. I have
attached the engine log and the VDSM log for that host.

Could someone please help me figure out what's causing this?
