@Daniel, I did all the testing before and came to the same result (as you are probably aware of) BUT with a different CONCLUSION.
I personally concluded that the use of swap partitions, if ever desirable, is (also) not desirable in the current case AND certainly not on an ephemeral disk, given that: 1 - a swap partition at the beginning of a device/disk can be efficient, but will lead to a waste of disk space, with this being static, 2 - a huge swap partition (if someone makes that strange mistake) will result in severe problems and performance issues, 3 - a swap partition at creation time considerably reduces "provisioning speed/performance", 4 - a swap partition can become huge (i.e. too large) if a VM is upgraded to a larger size (with a larger ephemeral disk), 5 - an OPTIMAL swap partition should be a function of memory (similar to logic introduced with cloud-config setting swap). Moreover, the swap partition as such can become obsolete, given the swap function(s) in cloud-init versions 0.7.6 and 0.7.7. In short, I have an issue with the procentual division of the disk, into a normal partition and a swap partition. The percentage assigned to the swap partition should be able to allow for - automated calculations of the percentage (via logic, to optimize swap space) - manual overrides of the automated calculations Kind regards.... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1374166 Title: Document how to add swap space on Azure resource disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1374166/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
