Hallo all,
I have 4 HDDs and I want to use mirroring and striping.
I am wondering what difference between the following two solutions is:
- raid0 on top of 2 raid1 devices (raid1+0)
- directly using the raid10 module
Perhaps someone can give me a hint what the raid10 linux module does in
difference to the combination of raid1 and raid0.
Another question:
How stable is the raid10 module in the linux kernel. I am currently using the
debian kernel 2.6.18 but I saw some patches from Neil and others for 2.6.21,
2.6.22 regarding the raid10 module. And their descriptions sound as if it
could be useful to integrate them. when using raid10.
Okay, backporting isn't complicated, but nevertheless the number of patches
makes me feel that raid10 is perhaps not that stable like raid0 and raid1 ???
Perhaps someone can blow away my fear :)
Best regards
Thimo Eichstädt

I have a few people who asked me this as well, RAID10 or similiar (SW). I
am not so sure, with RAID1 you can have your root disks on it and boot
from it using LILO/GRUB and it is proven pretty stable; can the same be
said about RAID10?
