Re: questions regarding file-system optimization for sortware-RAID array
The stripe and stride options do two things:
- shift block and inode bitmaps in each group to be on different disks
- align the block allocation to the stripe and stride boundaries to
avoid read-modify-write in RAID
The first one is irrelevant if the flex_bg option is used, since it already packs
the bitmaps together and achieves the same effect.
The second is meaningless for RAID-1 since
