Quite a bit. I can't create a file bigger than 4G, cat to a file bigger
than 4G or do anything to make it bigger than 4G.
ie:
cis209883# cd /mnt/smbfs
cis209883# /home/benjsc/bin/createfile filename 4294967296
cis209883# ls -l filename
-rwxr-xr-x 1 root wheel 4294967296 Dec 22 10:07 filename
cis209883# echo "This string will not be appended" >> filename
cis209883# ls -l filename
-rwxr-xr-x 1 root wheel 4294967296 Dec 22 10:07 filename
This seems like a nasty bug as well
cis209883# /home/benjsc/bin/createfile filename2 5368709120
cis209883# ls -l filename2
-rwxr-xr-x 1 root wheel 1073741824 Dec 22 10:08 filename2
cis209883# ls -lh filename2
-rwxr-xr-x 1 root wheel 1G Dec 22 10:08 filename2
Yet on a ufs partition:
cis209883# cd /mnt/raid
cis209883# /home/benjsc/bin/createfile filename2 5368709120
cis209883# ls -l filename2
-rw-r--r-- 1 root wheel 5368709120 Dec 22 10:10 filename2
cis209883# ls -lh filename2
-rw-r--r-- 1 root wheel 5G Dec 22 10:10 filename2
Cheers,
Benjamin
