[ovirt-users] Node not talking NFS to Node.

2015-11-26 Thread admin 
Hello 

Been trying to resolve a problem with my second node which does not want to
connect :

one of my 2 nodes are not connecting, the problem is that the Node cant talk
NFS to Node. the node used to function fine, after performing a hardware
upgrade and bringing the system back up it seems to have come up with this
issue. we also performed a yum update, updated around 447 packages.

Can someone please help me with this.

Thanks
Sol

Please provide us some logs from the affected hypervisor. vdsm.log and 
the result of "ip address show" should be a good starting point.

Hi

Ok, a bit of background, I¹m using this node/host with local storage, I am
able to bring up the Virtual machines on this node/host using my node/host
1. I have 9 live virtual machines running of the local storage on the
affected node/host(Node2) but this host does not connect. On the ovirt
manager I get the following errors :

2015-Nov-26, 12:03

Failed to connect Host hosted_engine_2 to Storage Pool Default



2015-Nov-26, 12:03

Host
 hosted_engine_2 cannot access the Storage Domain(s) 
attached to the Data Center Default. Setting Host state to
Non-Operational.




the affected node/host(Node2) has the following vdsm.log

Tried to manually mount the NFS share? The above is a clue from your logs.
