An example would be: `bsdlabel -w /dev/ad0s1e` - creating /dev/ad0s1ea In trying to set up a new server, I did this in the expected way. bsdlabel works correctly on 8.2, creating the nested slices. However, GEOM fails to create the appropriate /dev entry on 8.2 (works correctly on 6.X, have not tried on 7.X). I brought this up on #freebsd, the suggestion was to use ZFS. But, this means that it is not possible to upgrade existing 6.X servers that use this feature to a recent FreeBSD. I am presuming that this is just an oversight. Here is a thread from 2006 mentioning this feature: http://freebsd.1045724.n5.nabble.com/disklabel-differences-FreeBSD-DragonFly-td4038161i20.html >How-To-Repeat: bsdlabel -w <slice> bsdlabel -e <slice> Create several nested slices. GEOM will not create the appropriate /dev subdevices >Fix: >Release-Note: >Audit-Trail: >Unformatted:
