..interrestingly people here seem to focus my problem to ZFS.. but my
problem was to build an raid over 4 disks on my old i386 machine and that
failed with 2 different approaches.
I'm accepting that ZFS is a too big thing for the i386 architecture
and I possibly should leave it alone on that machine.
But my 2nd try with gvinum failed also ...why?
In the meantime I've set up the first two disks to a geom_mirror and
installed 2x swap and a 66G ufs on the mirror, successfully installed
10.2-Beta, pulled the sources with svn and rebuild the entire world and a
kernel yesterday. That worked flawlessly.
So the hardware is out of the question here.
It seems that geom_vinum is broken and it is broken on 9.3 10.1 and
10.2-Beta. There isn't an other possibility anymore.
Can someone please confirm this with a similar machine?
Proably I could atach an IDE disk and move the new build system to it
to give ZFS a 2nd try on the 4 SCSI Disks to prove if something changed n
the meantime or if a kernel with KSTACK_PAGES=4 would fix the ZFS problem.
I had running gvinum and gmirror on that machine in the past up to
8.4-stable. It seems that we've lost this possibility now..
