Storage plug-in question

[Mike Tutkowski <mi...@solidfire.com>]

Hi Edison,

I have a quick question for you.  :)

A week or so ago, I went through the process of setting up iSCSI storage to
be used from CloudStack with XenServer.

When I tried to set the storage up by creating a Primary Storage type and
selecting iSCSI as the protocol, the process did not work (I received an
error message that Primary Storage could not be created).

What I had to do was set XenServer up to see the iSCSI storage first, then
go into CloudStack and create a Primary Storage type by selecting the
PreSetup option.

I am wondering if in the storage_refactor branch we have solved this issue?
 For example, in the storage_refactor branch, the admin could associate a
Primary Storage type with the SolidFire plug-in.  When the user makes use
of a Compute or Disk Offering that leverages the Primary Storage type that
is based on the SolidFire plug-in, storage will need to be created (that's
the plug-in's job) and then associated with a Cluster.  If that Cluster is
running XenServer, will this work?

Basically, I just wanted to confirm that we expect this new plug-in
architecture will be compatible with all of the hypervisors that CloudStack
supports.

Thanks!

Hi Edison,

I have a quick question for you.  :)

[Edison] Do you have more detailed error messages? Adding an existing iSCSI target into xenserver host, should work.

What I had to do was set XenServer up to see the iSCSI storage first, then go into CloudStack and create a Primary Storage type by selecting the PreSetup option.

I am wondering if in the storage_refactor branch we have solved this issue?  For example, in the storage_refactor branch, the admin could associate a Primary Storage type with the SolidFire plug-in.

If that Cluster is running XenServer, will this work?

[Edison] Yes, that the PrimaryDataStoreLifeCycle will do, in the initialize method call, you can create an iSCSI LUN, then in attachCluster, you can attach it into one xenserver cluster.


Basically, I just wanted to confirm that we expect this new plug-in architecture will be compatible with all of the hypervisors that CloudStack supports.

Thanks!
