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