Fresh Setup Confirmation

[B3Technology]

Ok, folks.

I have rebuilt my setup a half dozen times and have come across problems every time, so I wanted to confirm that the way I am setting up this environment was following best practices.

First, here is my configuration...


When I am setting up the cluster I am choosing the 192.168.200.x network. But the curious thing is when I try and join the 2nd server using the Join information from the cluster it puts the IP address of 192.168.100.x in the IP Address field. So I have to manually join the cluster by unchecking the "Assisted Join" option and specifying the correct address. I also make sure to select the Primary link of the 192.168.200.x interface and the secondary as the 192.168.100.x interface.

1 of the common errors I get is a "permission denied - Connection Error". But if I ignore this and refresh my screen, everything works fine.

What other changes do I need to make to make sure that this environment is truly stable.?

Thanks for any thoughts on this matter.

Interested in this setup, why 2 ip's ?

Do your switches support MLAG ?

Otherwise i would go with active-backup bonding.

Or is the second ip for managment / sync ?

Thank you H4RO for your response.

According to what I have read we are suppose to have a dedicated network for the CEPH/Cluster for proper operations. So I created a separate 10G network just for the cluster and storage unit. We are running all of our GUESTS via iSCSI to the NAS/SAN unit.

Am I misunderstanding something here?

No, it's fine. There is no real HA involved, but that is also fine if you don't want to go that expensive route.

Ok thats fine. You should be all set then, just check the output of "pvecm status"
