It's much more complex than it seemed from your initial statement. :-) What you want in the end is e. g. /dev/da1s1a = / /dev/da1s1d = /usr (or maybe /usr/local) /dev/da1s2b = swap /dev/da1s3d = /bigstorage (or something similar) /dev/da1s3e = raw > For consistency we want to use the same slice configuration > for these large drives.

Then it looks to me that using gpt / gpart is the way to go... -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
