[Openstack] How To Cleanup SWAP in Compute Node
Hi, One of my compute node eats up swap, and it turns out to be a kvm process. So I have two questions: 1. How to release the swap? I tried terminating other instances on the same node, but it doesn't help. So can I use the normal approach like sync; echo 3 /proc/sys/vm/drop_caches, swapoff -a swapon -a on compute node? Will it be too dangerous? 2. What will cause the kvm process eating up swap? I don't think it possible to launch new instance in a cloud that is already full. Are there any other causes? Something I should avoid in the future? Thanks. PS: I'm coping with a cloud of Diablo release, which is handed over from a previous Ops. ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
Re: [Openstack] Is It Safe to Use The OpenStack Packages Distributed in Ubuntu 12.04 Official Repository?
Hi, So you're suggesting I should install from source. Which branch/tag should I use? branch stable/essex? tag folsom-3? And also I'm worrying about upgrading and/or migration. Is it expensive to adopt a newer version of openstack?

Hi Marek, Thanks for your reply. When Folsom comes out, I hope there'll be some sharing experiences on live-migration.

Till you find your way around, final release should be out and you can use it in production. (It's only a month or so away, and believe me, it will take you that time to install it, get to know it, and test if it suits your production scenario.) Just keep in mind, it's kind of development branch. We are done with our POC on essex. But if are about to proceed to production, it will be done on Folsom once it is out. (there are still lot of things to test till it's out) I have no experience with upgrades so far (one of the things to be tested), so I can't tell you how hard it is. I can imagine it really depends on your particular buildup.
