XFS force shutdown : EFSCORRUPTED

["中野 博之" <nakano@xxxxxxxxxxxxxxxxxx>]

 Hi XFS stuff.
 
I met a problem with XFS filesystem.

I am using kernel 2.4.18-xfs. Hardware is pentium3 800Mhz,128MB of RAM.
 
XFS goes to force-shutdown everytime when I execute my test suite.
Do you have any information for this issue?

My test suite consists of a shell-script and a compiled program.
It uses XFS command cvs tree (xfs-cmd.tar.gz) as a data for test.

My Shell-scrippt (org-g.sh) is :

  umount /dev/hda7
  /usr/src/cmd/xfsprogs/mkfs/mkfs.xfs -f  -l agnum=1,size=2000b /dev/hda7
  mount  /dev/hda7 /mnt/xfs
  cd /mnt/xfs
  tar zxvf /test/xfs-cmd.tar.gz
  /test/test_dev_read
  cd /test
  rm -rf /mnt/xfs/cmd

and my program (test_dev_read.c) is :

  #include <sys/types.h>
  #include <sys/stat.h>
  #include <fcntl.h>
  #include <unistd.h>
  #include <errno.h>
  #include <string.h>
  
  int main( argc, argv )
  int argc;
  const char *argv[];
  {
  int     fd,ret,i,error;
  char    bufl[4096];
  
          if( ( fd = open( "/dev/hda7" , O_RDONLY , S_IRWXU ) ) < 0 ){
                  printf( "error= %s\n" , strerror(errno) );
                  return;
          }
          for( i=0; i<1; i++ ){
                  ret = 40;
                  error =  read( fd , bufl , ret );
                  printf( "test  read1 finish = %x \n",(char)bufl[0] );
          }
          if ( lseek( fd, 4096*16, SEEK_CUR ) == -1 ){
                  printf( "error2= %s\n" , strerror(errno) );
          }

          for( i=0; i<1; i++ ){
                 ret = 40;
                 error =  read( fd , bufl , ret );
                 printf( "test  read2  finish = %x \n",(char)bufl[0] );
          }
          printf( "test program finish \n" );
 
          close( fd );
  }

This test suite shows following results:
