I used the troubleshooting guide at

documentation/how-to/troubleshooting/troubleshooting-nfs-storage-issues/

and exported using

(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)

This was for the DATA_DOMAIN not hosted storage but it may help.

My exports file has the same line, so I don't believe that's the problem. I went through the recommended steps on the troubleshooting guide and everything looks to be fine, but the problem still exists. The troubleshooting guide never came up in my previous googling of the problem though, so thanks for pointing me to that. =)

Subject: [ovirt-users] Hosted Engine/NFS Troubles

 

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] (org.ovirt.thread.pool-6-thread-34) [] Domain 'ca044720-e5cf-40a8-8b21-57a17026db7c:hosted_storage' was reported with error code '358'

2017-07-17 18:32:11,487 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (org.ovirt.thread.pool-6-thread-34) [] 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?
