Re: Alignment of RAID on specific boundary

Hello Mr. Rees and thank you for replying.

I have read this post and it is very good but it mentions alignment
of the partitions using special CHS values and LVM/ext4 options.

My partitions and both LUKS/LVM are aligned properly (at least i think
they are). I am worried about the alignment of RAID itself.
