Linux_raid1


Hi all,

I am learning raid1 mirroring, I am not understanding the concept of bitmap. Anyone knows any books or pdf materials which explains the operation of raid1 mirroring package. I am not comfortable with the concept of bitmap in it.


Thanks

Hello,

Read here - http://en.gentoo-wiki.com/wiki/RAID/...-intent_bitmap
Pretty much, bitmap enables faster RAID rebuild time due to a hard drive crash, etc.

Cheers,

Josh

HI corp769

i know the procedure to perform RAID 1 Mirroring. I want material that explains me the theory how actually IO (READ/WRITE) happens to the mirroring disks and the code flow atleast till generic_make_request. I a trying to analyse the code flow in lxr site for kernel 2.6.18, but since i am new to coding field, i am feeling difficult to follow it. (For example concept of superblock,rdev etc). So that if there is any material that explains the same, it would be easier to analyse the source code.

Thanks
-Nakul
