What is the motivation for having numeric filesystem names? Would it be better just to require that the filesystem name always starts with a letter? The code being modified has existed since 2007, so I'm wondering if this is a new problem, or if the filesystem was just created?

It seems that the failures still showing up are on older version before the fix landed. The fix is in 2.10.2 and 2.11. Marking as resolved and let's just reopen this if it reoccurs on a version containing the fix in the server code.
