I don't think so.  The rules for supported versions say that the MDC servers must be running the highest versions of the OS and Xsan software, and I think that means both/all of the MDCs.  From what Apple support told me, you *can* bring up an MDC running 10.5. [...]

Hi.
I recently installed Leopard 10.5.2 server that I want to use
as a MDC on my Xsan 1.4.2 configuration.  
 That said, I have another machine running OS X Tiger Server 10.4.11
that acts as a Primary MDC on a 1.4.2 Xsan. That server is connected to
a Brocade Fiber Switch and 2x XRaid boxes. [...]

I have had the chance to test Promise Raid and they are pretty fast.  True a single controller can control all drives and have the power to do it. 
 But at the same time the controller is so fast that you can assign 7 drives luns  to each of the controller and assign a 2 drives mirror raid for mdc to one of the controller and it will not much affect the data lun that is on the same ctrl. 
 Quite better than keeping MDC in data lun and quite better than dedicating a controller to MDC.  On multiple chassis, another story.  each config has is story..     Serge  Ordigraphe inc.

I had a similar experience. 
Into one machine I put a multi port Ethernet card, then deleted all  
the new ports in the network sys pref pane. 
After that, it would not accept a serial number. 

After reenabling the Ethernet ports, the problem was gone. [...]

Does it fail to assign even if you explicitly assign the serial number? 
(i.e. switch to the Computers list and select "Assign Serial  
Number..." from either the gear menu or via a right click)

Hi there,  
 if you use Apple's standard config script to set up an Xsan

I have found the same thing.  I have worked around it by running a script every 90 seconds that adds appropriate ACLs to any project files that lack them.  I've also created user specific capture scratch and render directories so the default permissions don't interfere with two users trying to capture footage for the same project.  It's ugly, but not nearly as ugly as what Final Cut is doing!  I find Final Cut's failure modes when dealing with permissions issues particularly galling:  trying to capture to a directory you can't write to? POOF! No more Final Cut.

One of the advantages of the new Promise RAIDs is, as I understand it,  
that one controller can control almost all over the drives/arrays and  
the other can be dedicated to the metadata LUN. So no lost drives

  Hi,       I am currently running OS X 10.4.11, currently up to date, with XSan 1.4.2.  They connect to a QLogic SANBox 5200 fibre switch, which also connects to three XServe RAID's.  The SAN is not mounted on my mdc.  In the system log of my metadata controller, I keep getting this line repeated over and over:      May  7 11:48:31 mdc xsand[91]: unable to open automount.plist for reading: No such file or directory  May  7 11:48:46 mdc xsand[91]: unable to open automount.plist for reading: No such file or directory  May  7 11:49:01 mdc xsand[91]: unable to open automount.plist for reading: No such file or directory  May  7 11:49:31 mdc xsand[91]: unable to open automount.plist for reading: No such file or directory  May  7 11:49:46 mdc xsand[91]: unable to open automount.plist for reading: No such file or directory  May  7 11:50:01 mdc xsand[91]: unable to open automount.plist for reading: No such file or directory  May  7 11:50:16 mdc xsand[91]: unable to open automount.plist for reading: No such file or directory       When I googled the error, I found this from http://discussions.apple.com/thread.jspa?messageID=6347797 :     This looks like two non-related problems: 1. the missing automount.plist.

Unlimited users license implies the unlimited number of clients  
connected to the server for file sharing through AFP, NFS, SMB or FTP.  
Metadata control is a different type of service. So, you can use a 10- 
user license for MDC.

We are putting together a quote for upgrading an XSan to version 2.0.  
The client is running a separate server as OD master. Do the Leopard  
server licenses on the MDCs need to be unlimited users or can we use  
ten use licenses? 

  

Since I am about to implement an XSAN (2.0) for a client I am wondering about the use of ACL's after I read this thread. It seems that problems only(?) arise if the ACL's are applied at the root of the volume BUT I would really like to  hear from deployments that use xsan 2 AND use ACL's on the subfolders on the volume - is this known to cause problems or not? 
 I would really like to avoid having to backup and restore 5-10 TB if it can be avoided sue to good planning ;-)   - TvE   On Thu, May 1, 2008 at 7:18 AM, T.K Sreekar <email@hidden> wrote:

    Not having access to and studied your specific case in depth, all I am saying is that you might want to completely disable ACLs for the entire volume at all levels (either through the GUI method Apple suggested or the command line method I suggested) and see if it fixes your issue. 
    If it does, you need to forget using ACLs from now on for this specific volume at all levels unless you want to rebuild the entire volume afresh and enable ACLs sans the root volume---the rebuild with ACLs sans root volume is not a fix BTW, there are still possibilities that ACLs can still get corrupted, but a lot of empirical evidence suggests that having enabled ACLs at the root level causes the current headaches several Xsan customers are facing across the globe. 
    Once you start hitting Microsoft style security descriptor errors  with fsm whinging and crashing in the controller controlling the volume, depending on the type of ACL corruption you have, you either rebuild the volume with ACLs sans the root level (and hoping for no corruption in future) or live without ACLs across the board.
