Anyone else experiencing issues with XSAN connectivity after upgrading to 10.8.5?

 

We are using XSAN for FinalCut X and it appears that very intensive reads/writes cause it to unmount the volumes on workstations.

 

We can also duplicate the error if we run Black Magic Disk Test on more than 1 machine on the XSAN at a time (works fine if we only are stressing 1 workstation.)

 

Before the update this was not an issue and we were working fine on 10.8.4.

 

The system logs are not telling me much. The fsmpm crash log header is below.

Anyone else having issues since the update with XSAN?

    Do you MDC's failover when this occurs?

    The MDC's do not appear to be failing over and have not given this crash message.

     

    The crashes only happen on the Workstations.

     

    I restarted the entire system (Workstations, Servers, and RAIDs) and that seemed to fix it for 2 days. Now it's back to crashing.

     

    We also appear to have some "ghost" volumes after it fails, where the volume will not show up in Finder but will show up in Terminal.

     

    That and everytime the machine is restarted it builds a new file in /cores which is taking up quite a bit of space.

    What do the workstation logs have to say and what do the server logs have?

    The server logs do not say much.

     

    The workstation logs state that "FSMPM is not responding" and a few moments later the volumes dismount from the workstation.

     

    The Volumes have never dismounted from the server, only the workstations.

     

     

    I have a far-fetched idea of what may be happening. The workstations are both Mac Pros (5,1) and have Pioneer BluRay Drives installed. Since the 10.8.5 update they have been disconnecting at random and the XSAN volumes follow the bluray drive.

     

     

    Also, an update on BlackMagic Disk Test. It does not appear to be the problem, I have retested it and used subfolders for each machine as the test area. The volumes stay mounted under stress.
