Note that stride and stripe width only make sense for RAI-5/6 arrays. For RAID-1 it doesn't really matter.

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 /dev/md0

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

Andreas, why is it relevant only in case of RAID5 or RAID6? regards, Martin On Fri, Mar 7, 2014 at 5:57 PM, Andreas Dilger <adilger@dilger.ca> wrote: > Note that stride and stripe width only make sense for RAI-5/6 arrays. > For RAID-1 it doesn't really matter. > > Cheers, Andreas > >> On Mar 6, 2014, at 13:46, Martin T <m4rtntns@gmail.com> wrote: >>

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? -JimC -- James Cloos <cloos at jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

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 -- -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- Olivier MARTIN phone: (33) 04 76 61 53 55 Projet IS2 06 08 67 93 42 INRIA Rhone-Alpes fax : (33) 04 76
