[Development] Maintenance break tomorrow Apr 1st

[Tony Sarajärvi]

Hi

We’ll be bringing the OpenNebula down tomorrow morning at 8:00 EEST for an upgrade.

We’ll update OpenNebula itself to version 5.10.1 as well as an implementation of using hugepages when running virtual machines.
We’ve seen it possibly eliminating the slowness they’ve been suffering. It seems like the slowness is due to vast amounts of memory allocations in a fragmented memory space.

Also, the latest firmware’s will be installed on the hosts. The firmware install will take aprox 1h per host, but that can be done for all of them in parallel.
After that we’ll have to deploy all the hosts, and it will take some time, since we have to upload all tier1 images to them. Because of this upload we’ll do it in batches of 5-6 hosts at a time.

First ones should be coming online at around 10 o’clock, if everything goes as planned. So give it an extra 2 hours as usual 😉

For our internal employees: the parked VMs have to be nuked. Save your work!!!
