The File Server stores volumes in partitions. A partition is a
filesystem or directory on the server machine that is named C</vicepX>
-or C</vicepXX> where XX is "a" through "z" or "aa" though "zz". The
-File Server expects that the /vicepXX directories are each on a
-dedicated filesystem. The File Server will only use a /vicepXX if it's
-a mountpoint for another filesystem, unless the file
-C</vicepXX/AlwaysAttach> exists. The data in the partition is a
-special format that can only be access using OpenAFS commands or an
-OpenAFS client.

The File Server generates the following message when a partition is nearly

Currently, the maximum size of a volume is 2 terabytes (2^31 bytes)
-and the maximum size of a /vicepX partition on a fileserver is 2^64
-kilobytes. (The maximum partition size in releases 1.5.34 and earlier
-is 2^31 kilobytes.)

-The maximum number of directory entries is 64,000 if all of the
-entries have names that are 15 characters or less in length. A name
-that is 15 characters long requires the use of only one block in the
-directory. Additional sequential blocks are required to store entries
-with names that are longer than 15 characters. Each additional block
-provides an additional length of 32 characters for the name of the
-entry.
