Re: Place Volume Snapshots on a different Secondary Storage

Andrija is spot on here nd in addition once a snapshot chain has started using a particular sec storage all snapshots linked to that VM volume will always use the same sec storage. New snapshots will randomly select a sec storage and I believe the available capacity is not taken into account -

Re: Cloudstack and xenserver 6.2 Pros and cons: openvswitch vs bridge

General rule of thumb is to leave at the default of Open vSwitch if not using Security Groups, and to switch to Linux Bridge if you are using Security Groups (Basic or Advanced) Regards Geoff Higginbottom CTO / Cloud Architect D: +44 20 3603 0542 | S: +44 20 3603 0540 | M: +447968161581 geof

Thanks Andrija and Geoff for the info... Just want your opinion on this: Is there any way/ steps to transfer data (volumes/ Snapshots/ Templates) from the first Sec Store (60GB) over to the new Sec Store (200GB); assuming I want my new Sec Store to be the only Secondary Storage available for t

RE: Cloudstack and xenserver 6.2 Pros and cons: openvswitch vs bridge

Hi, Here are my thoughts. Correct me if I am mistaken. Pros: - OVS should give more control over network than usual Linux bridge. CS has OVS plugin for that. Can't use it, because of (see below). - XenServer uses OVS by default (though trough XAPI). Cons: - It

Re: Stable updated System VM template

Hi Geoff, We have deployed Cloudstack 4.3 does cloudstack 4.3.1 available and if it is available then does systemvmtemplate 4.3.1 works with 4.3? currently it is venilla installation so we can upgrade from 4.3 to 4.3.1 therefore above clarification would really help to deploy stable version.

Preventing new deployments to specific primary storage

I currently have two primary storages, where one of them are getting full. Thus I need to prevent further allocations to it. Is it enough to add a storage tag to it, or will that mess up existing volumes? -- Erik

Re: Stable updated System VM template

Hi Goeff, Thnaks, in order to deploy systemvm template 4.3.1 we also require cloudstack 4.3.1 i think we have deployed 4.3 only. So i guess we have to use latest version of 4.3 version template only. Let me know if i have not understood correctly. Thanks Tejas On Fri, Nov 28, 2014 at 3:08

Re: Preventing new deployments to specific primary storage

if you just add storage tag it will just have a tag attached to it. This single change will not be your solution and also will not cause issues. If no compute/storage offerings are referencing that tag - that just means that the volume might/will also be placed on that primary storage and also on

Re: Reserving space for snapshots.

Hi Jakub, It depends how much space you’ve left and how big is the snapshot disk size. In Global and cluster settings search for disablethreshold, there are two disablethreshold limits for storage that you need to set. You need to specifically do it for at least existing clusters, the global se

RE: Cannot transit agent status with event AgentDisconnected for host

Hi Aschim, Which zone are your trying to configure - basic or advanced? Did you use "security groups" as isolation method? In the latter case you should switch to bridge mode as Erik suggested. I guess you may also have problem with primary storage registered at your XenServ
