2 a.m.
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:

However, the engine dashboard still shows that only ~93GB of RAM are available to the
cluster (screenshot below).

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.
Thanks,
Joe

That was it.
It popped up within an hour or two.
I guess patience is the name of the game.
Thank you!
