Re: max file size.

[Matt Riben <matter_(_at_)_superlink_(_dot_)_net>]

due to the lack of responses to my previous post, i think i need to make
it more clear what im trying to do...

% dd if=/dev/zero of=/var/vnd/pd0 bs=1k count=4096000
# vnconfig -v -c svnd1 /var/vnd/pd0

i can create a 4gig file with dd, and after using vnconfig i can label it
in disklabel... only when i try to newfs it...

# newfs /dev/rsvnd1d
write error: 8191999
wtfs: File too large

#limit
cputime         unlimited
filesize        unlimited
datasize        1048576 kbytes
stacksize       32768 kbytes
coredumpsize    unlimited
memoryuse       unlimited
descriptors     1772 
memorylocked    unlimited
maxproc         532 

i also checked the the getrlimit(2) page.
     RLIMIT_FSIZE    The largest size (in bytes) file that may be created.

im confused though, i can create the file with dd, no problem... i just
cant newfs it...

i think newfs is dying here:
/usr/src/sbin/newfs/mkfs.c
  1182          n = write(fso, bf, size);
  1183          if (n != size) {
  1184                  printf("write error: %ld\n", bno);
  1185                  perror("wtfs");
  1186                  exit(36);
  1187          }

this is 2.3 on an i386, if that makes a difference... any suggestions on
what im doing wrong here would be great...

thank you.
