Hi-
We are beta testing the new Sonnet Technologies VFibre shared storage system:
http://www.sonnettech.com/news/pr2010/pr091010_fusionrx1600vfibre.html
It is a fiber and ethernet based SAN with a windows server built in to a 48TB fibre channel raid (using SAS internally) using metaSAN as the metadata server and windows computer as the master. We've had it for about 2.5 weeks now. I hope I explained all that correctly, I am new to the SAN admin world.
Right now we have two metaSAN licenses (desktops connected via fibre), and run between 1-3 metaLAN licenses (ethernet). These are all running on Macs, the windows server is NTFS, of course.
Everything was going pretty well until this past weekend when without warning, the San disappeared from everyone's desktop, knocking all files offline in FCP. The volume is still listed as mounted on the windows server, but the SAN is "Not Available" according to metaSAN. I then have to go in to metaSAN and add the volumes back to both metaSAN and then redefine the metaLAN volume as well. Everything then mounts back up, and away we go.
No data loss or corruption of any sort, but it is a bit disconcerting that the volumes keep getting "lost" on the master. This has now happened two more times since Sunday for a total of three times in a week. Here's a log from a laptop based ethernet connection:
08/17/11 16:26 Volume "HighInFibre" was removed from volumes list.
08/17/11 16:26 Failed to process master changed notification for volume "HighInFibre".
08/17/11 16:26 Volume "HighInFibre" was unmounted from client.
08/17/11 16:26 Volume "HighInFibre" was removed from volumes list.
08/17/11 16:26 Master changed notification received for volume "HighInFibre".
08/17/11 09:04 Volume "HighInFibre" was mounted as client.
08/17/11 09:04 Volume "HighInFibre" was added to volumes list.
08/17/11 09:04 Volume "HighInFibre" was added to volumes list.
08/17/11 09:04 Currently logged system user set successfully.
08/17/11 09:04 Trying to set currently logged system user...
I also have logs from the master if you need them. Teamviewer is also installed on the server in case you want to take a look.
Any ideas on what is going on here? I have also been working with Sonnet tech support, but my contact had to go away on emergency so I figured I would try here until he is able to respond.
Thanks so much,
Jeremy
