<P><FONT size=2>Hello,<BR><BR>I use dmsetup as replacement for ataraid (2.4
kernel) on many system to setup striped and mirrored discs<BR>on a 2.6.* kernel
system. As long as I use striped mapping schema I have no problems and they work
very well.<BR>Now I want to setup my mirror set of disc,but frist I miss a
How-To of possible options to setup mirror map e.g. (mirror core 1 or 2). When I
create the mirror map I do following:<BR>raid1.mirror > 0 `blockdev --getsize
of smallest disc in mirrorset` mirror core 1 1024 2 /dev/hde 0 /dev/hdg 0<BR>the
map of partitons are created as linear mapping. I can access the mirrorset but,
when I write<BR>image restore to the mapped mirrored discs they got unsynced
after sometime and the hole datastrature are bad.<BR>Here are some specs of my
system<BR><BR>Prepatched 2.6.8.1 kernel with DM compiled in
(zero,mirror,snapshot target)<BR>glibc-2.3.4 Branch 20040808<BR>binutils
2.15.90.0.1.1-r3<BR>gcc-3.4.1-r2<BR>util-linux-2.12-r4<BR>device-mapper-1.00.19-r1<BR><BR>Any
hints and maybe a little how to are welcome<BR>Thanks for
assistance<BR><BR><BR>Mit freundlichen
