[Openstack] two or more NFS / gluster mounts

2012-12-20 Thread Andrew Holway
Hi, If I have /nfs1mount and /nfs2mount or /nfs1mount and /glustermount can I control where openstack puts the disk files? Thanks, Andrew ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe :

Hi Andrew, Is this for glance or nova ? For nova change: state_path = /var/lib/nova lock_path = /var/lib/nova/tmp in your nova.conf For glance I'm unsure, may be easier to just mount gluster right onto /var/lib/glance (similarly could do the same for /var/lib/nova). And just my £0.02 I've

Hi David, It is for nova. Im not sure I understand. I want to be able to say to openstack; openstack, please install this instance (A) on this mountpoint and please install this instance (B) on this other mountpoint. I am planning on having two NFS / Gluster based stores, a fast one and a

Hi Andrew, An interesting idea, but I am unaware if nova supports storage affinity in any way, it does support host affinity iirc, as a kludge you could have say some nova compute nodes using your slow mount and reserve the fast mount nodes as required, perhaps even defining separate zones for

Ah shame. You can specify different storage domains in oVirt. On Dec 20, 2012, at 4:16 PM, David Busby wrote: Hi Andrew, An interesting idea, but I am unaware if nova supports storage affinity in any way, it does support host affinity iirc, as a kludge you could have say some nova

I may of course be entirely wrong :) which would be cool if this is achievable / on the roadmap. At the very least if this is not already in discussion I'd raise it on launchpad as a potential feature. On Thu, Dec 20, 2012 at 3:19 PM, Andrew Holway a.hol...@syseleven.dewrote: Ah shame. You

mmm... not sure if the concept of oVirt multiple storage domains is something that can be implemented in Nova as it is, but I would like to share my thoughts because it's something that -from my point of view- matters. If you want to change the folder where the nova instances are stored you have

Yes, I'm really agree with Diego. It would be a good choice for submitting a blueprint with this storage feature based on tenants. According to current quotas control, it limits the: - Number of volumes which may be created - Total size of all volumes within a project as measured

Hi John, Yes, that's a really good solution. It is exactly what the StackOps Enterprise Edition offers out of the box. It's a simpler alternative assuming you are big enough to have several clusters of compute nodes, and each cluster with different quality of service preassigned. And it works...
