SharedMountPoint will let you add it, but I believe the allocator will still consider it as shared, even in a single-host cluster. There is the same issue with the similar PreSetup option on XenServer.
This adds a lot of confusion. For example, to use the local storage you will need to use disk/compute offerings with shared = true. I filed an enhancement request to add proper support for this: https://issues.apache.org/jira/browse/CLOUDSTACK-4712 Best regards, Kirk On 09/13/2013 01:48 PM, Edison Su wrote: > > >> -----Original Message----- >> From: David Ortiz [mailto:dpor...@outlook.com] >> Sent: Friday, September 13, 2013 1:33 PM >> To: users@cloudstack.apache.org >> Subject: RE: Support for multiple Local Storage volumes >> >> That's actually how I have my primary storage setup using a gfs2 cluster.
