This is what I had expected after reading the man pages, though I would think -b 65560 -f 8192' would be a bit more reasonable in this day of bloated file formats. it's been years since I have hit a problem with lack of inodes. Probably around 1993 on an old SparcStation 1 running SunOS and then only due to a bad assumption I made when 'newfs'ing it. Again, thanks for the advice. At very least it will save me a bit of time! --=20 R. Kevin Oberman, Network Engineer - Retired E-mail: kob6558@gmail.com
