Re: questions regarding file-system optimization for sortware-RAID array
Note that stride and stripe width only make sense for RAI-5/6 arrays.
For RAID-1 it doesn't really matter.
Cheers, Andreas

questions regarding file-system optimization for sortware-RAID array
Hi,
I created a RAID1 array of two physical HDD's with chunk size of 64KiB
under Debian "wheezy" using mdadm. As a next step, I would like to create
an ext3(or ext4) file-system to this RAID1 array using mke2fs utility.
According to RAID-related tutorials, I should create the file-system like
this:
# mkfs.ext3 -v -L myarray -m 0.5 -b 4096 -E stride=16,stripe-width=32

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

Re: questions regarding file-system optimization for sortware-RAID array
Andreas,
why is it relevant only in case of RAID5 or RAID6?

Vorbis vs Opus
Does vorbis have any niches of technical superiority over opus?
Or is compatibility with older hard- and software the only benfit?
Put another way, is there any reason to prefer vorbis over opus for
music on new sortware or platforms?

R mode for emacs
Hi all,
I wonder if there is a R mode for emacs which highlights the R syntax.
If there is one, I would be interested in downloading the latest version
.
regards,
Olivier
