It's one program to learn, not many. The syntax of all geom(8) programs is the same. And actually most of the GEOM classes (gconcat, geli, gjournal, glabel, gmirror, gnop, graid3, gshsec and gstripe) are controlled by one program - geom(8), eg. # geom disk list # geom mirror label foo0 da0 da1 # geom mirror label foo1 da2 da3 # geom stripe label foo mirror/foo0 mirror/foo1 # geom raid3 label bar da4 da5 da6 # geom concat label baz stripe/foo raid3/bar # geom eli label concat/baz # geom eli attach concat/baz # geom journal label concat/baz.eli # geom label label complex concat/baz.eli.journal # newfs -J /dev/label/complex > > I've found gmirror and gstripe to be fantastically stable.

The volume manager from ZFS works already just fine, ie. one can configure UFS on top of RAID-Z for example, but I'm not going to bring it in before the entire port is ready. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
