Hello List,

Just wondering: is an md mirror setup under 2.6 compatible with 2.4? 
Basically: I want to downgrade a machine currently running 2.6.0 to 2.4.24, 
but it's setup with a mirror raid that I don't really want to bother setting 
up again.

Yes, as long as you're not trying the new raid6 code (very experemental
right now).

maybe not quite yet ready for prime-time, but nontheless very impressive in 
terms of performance!

an 8-disk RAID6 array with a chunksize of 64K sustains 92MB/sec streaming 
filesystem throughput here @ 30% CPU utilization.


cheers,

lincoln.
