FW: Re: md5 fail on large file

[Marco Berizzi]

Me again. I think I have found which is the problem.
After I have copied the file from NT4TSE to samba, I have run
df on the filesystem, and the used space was minor than the
filesize printed by ls -l

ls -l priv.edb

-rwxr--r-- 1 user group 5393883136 Apr 28 10:58 priv.edb

du priv.edb

4194364 priv.edb

df

df /dev/hda8 99396660  41994828  95201832  5% /mnt/data

My env: linux-2.4.26. /dev/hda8 is XFS, samba-3.0.2a Slack 9.1

Comments?
