xsan client mds errors

I have 2 [i]Lion/i MDCs and 5 [i]Snow/i clients.
The below errors are showing up on the Snow clients.

7/6/12 11:20:27 AM com.apple.metadata.mds[52] XSANFS_FSCTL_SpotlightRPC fsctl failed (errno = 45)ERROR: _MDSChannelInitForXsan: _XsanCreateMDSChannel failed: 45
7/6/12 11:20:27 AM mds[52] (Error) Message: MDSChannel RPC failure (fetchPropertiesForContext:) [no channelAccessToken]
7/6/12 11:20:27 AM com.apple.metadata.mds[52] ERROR: _MDSChannelXsanFetchAccessTokenForUID: dead channel
7/6/12 11:20:27 AM mds[52] (Error) Store: {channel:0x101a41500 localPath:'/Volumes/Media'} bring up failed -- will retry

Spotlight on the clients is set to ignore the "Media" volume, and I turned off Spotlight for the volume in Xsan, but these errors persist and they're filling up log files.

Mountain Lion drops support for xserve 2008

Forums: 

I was in the middle of acquiring components to use in a new xsan build. 2 of which are 2x 3.0Ghz xserve (2008) for MDC. But there are unconfirmed list of dropped computers in Mountain lion and they are on the list. I dont think I would build a production xsan with the brand new os/xsan 3 but if there is never the option too upgrade show I look at getting newer MDC? I looked at the mac mini but its geek bench score was lower then the 8 core 2008 xserve.

Expanding Volume Woes

We expanded one of our volumes today and had some interesting results, I'm hoping someone might have seen this and can offer a resolution,

Config
We expanded our VTRAK storage by stacking on an expansion chassis. We formatted the volume with Apple's preconfigured scripts, all logs show that went fine and the jobs are completed. We have a one 2TB LUN and pool for metadata and two 10 TB LUNs in a single pool for video. We added two additional 10 TB LUNs to the existing 20 TB pool for a total of 40TB. We're running XSAN 2.2.

Problem
We ran the expansion via XSAN to add the new LUNs to the current pool, all indications are that it went fine. The new pool and volume shows up as 40TB as you would expect. However, we do not have any more free space. We started with 3.75TB of free space, even though we expanded to 40TB we still have 3.75TB of free space according to XSAN admin, Finder, and cvadmin all indicate that we now have doubled the capacity of our volume but have not added any free space.

Attempted resolutions:
Log files indicate no problems. We have incrementally rebooted everything and also performed a full shutdown.

Any ideas where our free space is?

McData Sphereon 4500 connection issue

Forums: 

Having a bit of an issue getting the workstations to link. They are connected via the orange fibre cables with the little metal adapters. The 2 Xserves and the 2 RAID units are connected with the white Apple FC cables and have no problem linking. These orange FC cables should be fine, as they were working on our now decomed SANbox switch.

Anyone have any history with this switch that might be able to shine some light on why the orange cables are the only ones not linking? Thanks!
