Check the fsck man page:

fsck  [  -sAVRTNP  ]  [  -C [ fd ] ] [ -t fstype ] [filesys ... ] [--]
[fs-specific-options ]


     Options to different filesystem-specific fsck's are not standardized.  If
in  doubt, please  consult the man pages of the filesystem-specific checker.
Although not guaranteed, the following options are supported by most file system 

  -a     Automatically repair the file system without any questions  (use
this  option with  caution).   Note  that e2fsck(8) supports -a for backwards
compatibility only.  This option is mapped to e2fsck's -p  option  which  is
safe  to  use, unlike the -a option that some file system checkers support.

or even better the e2fsck page:

e2fsck   [  -pacnyrdfkvstDFSV  ]  [  -b  superblock  ]  [  -B  blocksize  ]
[ -l|-L  bad_blocks_file ] [ -C fd ] [ -j external-journal ]
[ -E extended_options ] device

  -a   This option does the same thing as the -p option.  It is  provided  for 
backwards  compatibility  only; it is suggested that people use -p option 
whenever possible.

  -p   Automatically repair ("preen") the file system without any questions.
