I upgraded one client computer to Mavericks and now it will not mount my XSAN. The XSAN is run from 10.6 Server on an XServe. I did update the XSAN to 2.2.2 but that did not help. I would love to load Mav onto all my computers but not until this issue is solved.
XSan 3 is included with the server app, no serial numbers are required any more. If you are scared do a CCC backup of your current server, upgrade to mavericks, and if it doesnt work out restore your CCC backup.
Just dont mess with any LUNS or Volumes if mavericks doesnt work.
