Adding physical RAM to the hosts
As readers will already know, I have three oVirt hosts in a hyperconverged cluster. I had a DIMM with too many errors on it, so I scavenged from a spare server that I had in my office precisely for this purpose. I went ahead and replaced all of the RAM, because the DIMMs in my spare were a different speed. While I was at it, I doubled the RAM on this 1 oVirt host. So now, two hosts have 32GB each. And the 3rd host now has 64GB. So total, I should have 128GB of RAM available to the cluster. The engine recognizes that the host now has 64GB of RAM. Screenshot below: [Screenshot from 2021-04-12 19-59-59.png] However, the engine dashboard still shows that only ~93GB of RAM are available to the cluster (screenshot below). [Screenshot from 2021-04-12 19-58-15.png] Should I be worried that the oVirt dashboard hasn't updated to ~128GB (or a bit less, I guess)? Do I need to do anything else?

How long had it been running before taking the screenshot? Especially if the hosted engine stayed active - it can take DWH some time to update (it doesn't poll for this info often, not sure on the specifics) Give it a good day and see if it updates on the dashboard. Further, have a look at the Cluster Hosts page and see if RAM usage is consistent with having 64GB rather than 32GB.

That was it. It popped up within an hour or two. I guess patience is the name of the game. Thank you! Sent with ProtonMail Secure Email. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Monday, April 12, 2021 8:07 PM, Joseph Goldman <joseph@goldman.id.au> wrote:
