Finder crashes after xsan finder copy, Apple is stumped
I have been seeing a problem on my two xsan environments. Once or twice a week, an xsan client will become unresponsive after a finder copy or file transfer. When it happens on the client, the mounted xsan volume is slow to display its contents, or will show nothing at all when there is 12TB of data there. When the client is in this state, if I do a "get info" on the mounted volume, the "more info" window says "Fetching" and there is a spinning gear. the client never recovers from this state, and has to be power cycled to break free of this funk. If I go into xsan admin and try to unmount the volume from the problem client, it will not let me unmount it. I have seen this on my xserve and MacPro clients. I am running all the current softwares on the os and xsan. I first experienced this issue on one san environment, then noticed it on a completely different san. I have un-installed and re-installed the os and xsan on the clients and un-installed and re-installed the os and xsan on the MDC's to no avail. I have destroyed one of my xsan volumes and rebuilt it and the problem came back.
I have been working with high level Apple XSAN engineers on this problem since May and they have no idea why this is happening. I have been sending them EDC reports after the issue and all the logs are fine.
Has anyone else experienced anything like this? Sorry for the long post, but this issue is driving me crazy.
