I have a system running 5.4-STABLE. I created a geom_stripe disk for
/usr. It works fine except that upon reboot, the stripe attempts to
load itself twice and thus fails. Therefore, since I have no /usr, the
system comes up in single user mode. At that point I can do 'kldunload
geom_stripe' and then 'kldload geom_stripe' to get the stripe built and
finish booting my system. I sent a problem report describing this
behavior. http://www.freebsd.org/cgi/query-pr.cgi?pr=83521 Please see
it for details.
Based upon the information in the pr, the commiter suggests clearing all
metadata on the stripe providers and starting over.
When I built this system, I configured the disks using sysinstall. I
used the "dangerously dedicated"mode just as I had when I ran the 4.x
series. I suspect my problems occur because geom_stripe doesn't get
along well with disks that are "dangerously dedicated".
Anyway, my system has 2 9gb drives (da0 and da1) that I wish to use for
the main system. I want a 500mb slice as /dev/da0s1a for '/', a 500mb
slice as /dev/da1s1b for swap, and the rest of each drive as
/dev/daXs1d. I will build my stripe with /dev/da0s1d and /dev/da1s1d
and mount it at /usr. Other directories such as /var, /home, etc. will
be symlinked to /usr/var, /usr/home, etc.
I have remote console access to this machine and want to attempt to
rebuild the system remotely. If I mess up, it's not too difficult to
physically get to the box but I would like to avoid it if possible. I
have another disk on the system (ad0) that is available and large enough
to hold the contents of both da0 and da1. Can I backup my system, do
the needed operations on da0 and da1, restore da0 and da1, reboot, and
still have a working system? I've never used fdisk, bsdlabel, newfs,
and whatever else I might need from the command line. Besides the man
pages, are there any guides for what I want to do? Even a simple "first
this, then this, then this" type of guide will help me get started.
I'd appreciate any help or suggestions on the best way to accomplish
this task. I would also appreciate any second opinions regarding other
ways to get geom_stripe working properly on this box.
Thanks,
Drew
