Hi,
I'm planning to use bitmaps on some of our RAID1 arrays.
I'm wondering how bitmaps are handeled by older kernels.
Eg: I create a raid array with a bitmap under a 2.6.15 kernel.
I now want to boot under 2.6.12, or even 2.4
Hos is it handeled?
Will it work even if this is my / partition?
On older kernel will not notice the bitmap and will behave
'normally'.
strange,
last time i tried an older kernel would refuse to activate an md with a
bitmap on it.
I am far from home on a business trip and i don't have kernel-sources at
hand, but i seem to remember that the kernel was very strict on the
feature bitmap in the superblock.

I experienced the same strange behavior.
Bitmap was created on 2.6.15, tried to boot 2.6.14 and /dev/md0 was not
started :$.
Strange.....
