Dear oVIrt,

 

This is my third oVirt platform in the company, but first time I am seeing following logs:

 

“2019-08-07 16:00:16,099Z INFO  [org.ovirt.engine.core.bll.provider.network.SyncNetworkProviderCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-51) [1b85e637] Lock freed to object 'EngineLock:{exclusiveLocks='[2350ee82-94ed-4f90-9366-451e0104d1d6=PROVIDER]', sharedLocks=''}'

No active host in the DC is reporting it as problematic, so clearing the domain recovery timer.”

 

Can you help me understanding why is this being reported?

 

This setup is:

 

5HOSTS, 3 in HA

SelfHostedEngine

Version 4.3.5

NFS based Netapp storage, version 4.1

“10.210.13.64:/ovirt_hosted_engine on /rhev/data-center/mnt/10.210.13.64:_ovirt__hosted__engine type nfs4 (rw,relatime,vers=4.1,rsize=65536,wsize=65536,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,clientaddr=10.210.11.14,local_lock=none,addr=10.210.13.64)

 

10.210.13.64:/ovirt_production on /rhev/data-center/mnt/10.210.13.64:_ovirt__production type nfs4 (rw,relatime,vers=4.1,rsize=65536,wsize=65536,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,clientaddr=10.210.11.14,local_lock=none,addr=10.210.13.64)

tmpfs on /run/user/0 type tmpfs (rw,nosuid,nodev,relatime,seclabel,size=9878396k,mode=700)”

 

First mount is SHE dedicated storage.

Second mount “ovirt_produciton” is for other VM Guests.

 

Kindly awaiting your reply.
