When you say "random" is there any logic or reasoning behind the choice it makes? Does it do some kind of round robin, or pick based on which secondary storage repo has the most space available? Or is it really just completely random... and if it is, why?

All the public templates will be replicated to all the secondary storage for redundancy but private templates would be kept in one of the randomly chosen secondary storage. Snapshots will be randomly copied to one of the secondary storage (the chain of incremental snapshots are kept on the same secondary storage.) -----Original Message----- From: Tamas Monos [mailto:tam...@veber.co.uk] Sent: Thursday, September 20, 2012 3:11 PM To: cloudstack-users@incubator.apache.org Subject: RE: Multiple secondary storage Hi, As far as I am aware if you are using more than one secondary storage then the system will use both storage but will not replicate any data. This means if your snapshot is stored on a secondary storage that is in Error state/down then any operation related to that data (template,ISO,snapshot) will error out/fail and there is no way to recover from it unless you bring the storage back online or via database hack. You will still see everything on the GUI as it does come from the database so make sure your storages are running. Use NFS failover or redundant storage hardware. I'm not sure about the latest version I'm on 3.0.2 Regards Tamas Monos DDI +44(0)2034687012 Chief Technical Office +44(0)2034687000 Veber: The Hosting Specialists Fax +44(0)871 522 7057 http://www.veber.co.uk Follow us on Twitter: www.twitter.com/veberhost Follow us on Facebook: www.facebook.com/veberhost -----Original Message----- From: Bryan Whitehead [mailto:dri...@megahappy.net] Sent: 20 September 2012 09:45 To: cloudstack-users@incubator.apache.org Subject: Multiple secondary storage If I add more than 1 secondary storage to a zone, are they all treated different? Is there replication going on like copying templates and snapshots between the two? If I have a template or snapshot on a secondary storage that is down do i still see it in the GUI but am just unable to use it? -Bryan
