Multiple secondary storage options?

[Willard Rathjen <wi...@appcore.com>]

Hey guys,

I have an issue I need to resolve and I haven’t been able to find any supporting documentation. If I have multiple secondary storage options in my zone how does Cloudstack choose which NFS share to use for any given snapshot, template, or ISO? If I wanted to have fine-grained control over which secondary storage share is selected for any given operation how would I go about doing so?

Thanks,

Willard Rathjen

Willard,

When you have multiple secondary storage devices in a zone the following basic rules apply.

1. Public templates, public ISOs and System VM templates are replicated to every sec storage.
2. Private templates and ISOs are only copied to one, randomly chosen sec storage.
3.  First snapshot is copied to one randomly chosen sec storage, and then all other related snapshots are copied to the same sec storage.
