If you're using "df" or "du" to determine the amount of space taken up, note that when the BLOCKSIZE environment variable isn't defined, those commands will give the sizes in 512-byte blocks (at least, they do on my system). If BLOCKSIZE is set to "K", they'll answer in 1024-byte blocks. > Is there anything else I can do to reduce the space used on > the hard drive? I haven't tried this, but to reduce space wasted by many small files you might dd the CD-ROM to a file on the hard drive, then use vnconfig to attach that file to a vnode (you must configure your kernel with "pseudo-device vn"), mount it, then have Samba to make the mount point available to the Windows clients. Perhaps something similar to: # dd if=/dev/acd0c of=/bigdisk/mycd.iso # vnconfig vn0c /bigdisk/mycd.iso # mkdir /foo/mycd/ # mount_cd9660 /dev/vn0c /foo/mycd/ # vi /usr/local/etc/smb.conf would do it. __ Trevor Johnson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
