// test6.data:  Checks the error conditions of filling up the file table and
// using all of the inodes.  It will first create enough files to fill the
// file table.  Then it will begin closing files and adding new ones until
// the number of inodes have been exhausted.

// 1. Format the disk with 100 blocks total, of which 3 are inode blocks
formatDisk 100 3

// 2. Create 21 files to fill up the file table

//    its own, then shutdown and quit the simulation.
