Hi Marko,
Is seems that there's a connectivity problem with host 10.210.13.64.
Can you please make sure the metadata under /rhev/data-center/mnt/10.210.13.64:_ovirt__production/6effda5e-1a0d-4312-bf93-d97fa9eb5aee/dom_md/metadata is accessible?

Regards,
Shani Leviim

Hey Shanii,

 

Thank you for the reply.

Sure, I will attach the full logs asap.

What do you mean by “flow you are doing”?

 

Kindly awaiting your reply.

Hi,

Can you please clarify the flow you're doing?

Also, can you please attach full vdsm and engine logs?

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.
