Thanks, Tim! Do you know of a good doc on the web I can view to see specifically what these numbers mean (like what they include and don't include)? On Fri, Jan 31, 2014 at 2:29 PM, Tim Mackey wrote: > Mike, I've confirmed that the data items map as you suspected to XenCenter. > In this case

Mike, I've confirmed that the data items map as you suspected to XenCenter. In this case the values had a rounding effect just on either side of 20.05 respectively to create the observed numbers. On Thu, Jan 30, 2014 at 6:37 PM, Mike Tutkowski < mike.tutkow...@solidfire.com> wrote: > Great - th

Hi Tim, You are correct that I was looking at XenCenter. Below is the output from xe. It looks like physical-size (below) corresponds to total in XenCenter, physical-utilization (below) corresponds to used in XenCenter, and virtual-allocation (below) corresponds to allocated in XenCenter. Does t

I'm assuming that's the value from XenCenter. What does the cli say? I could see this being just a formatting question. On Jan 30, 2014 5:59 PM, "Mike Tutkowski" wrote: > Hi, > > Does anyone know how a XenServer SR could (correctly) say more space is > being used than is allocated? > > This is wh

Just as an FYI to those it may concern: The way I got around this issue with XenServer is to use a SolidFire feature we refer to as Volume Access Groups (VAGs). A VAG is essentially a way to map a host IQN to the volumes it can access on the SAN without using CHAP. For the sake of consistency (a

One alternative I have is to abandon using SolidFire's multi-tenancy ability (separating volumes by accounts for reporting purposes). If I only used one uber account, then I'd only be using one set of credentials. Another is more work and would have to wait until 4.4: Add logic to the storage plug

The problem with doing that is during host reboot. Then only one of the credential sets will be used to do the discovery, and on each reboot a discovery will occur. It'll also have issues with multipath. There will also be an issue during pool join, and there could be replication issues in xenstor

We have noticed if I ssh into XenServer and delete the file /etc/iscsi/ 10.10.8.108,3260 (where 10.10.8.108 is our storage's IP address and 3260 is the port) that I can create SRs using different CHAP credentials. Can anyone think of a "got-cha" here? Thanks! On Wed, Dec 18, 2013 at 3:18 PM, Ti

Re: XenServer SR Question

Mike, I'm referring to the open-iscsi code used by XAPI. XAPI has a storage manager API which deals with all the SR management. It's also where the issue you're running into exists. In terms of clearing the connections and credentials, the easiest way is via a reboot. Since your using multiple

Hey Tim, When you refer to modifying the storage manager, are you referring to CloudStack? Perhaps you are referring to CitrixResourceBase, which is where we discover and log in to iSCSI targets. Do you know of a way to delete those cached CHAP credentials via XAPI so when new ones are used for

Re: XenServer SR Question

2013-12-18 Thread Tim Mackey
Unfortunately what you're experiencing is how it works. While XenServer does support different CHAP credentials by SR, it only supports a single CHAP credential for discovery. It can be made to work, but you'd need to either modify how the storage manager works to pull it off, or rewrite some of
