similar to: Calculating stride values?

All, I'm requesting comments from the expert readers of ext3-users on these notes for tuning ext3 for performance. Most helpful would be feedback pertinent to RHEL 5; as XFS isn't supported under Red Hat Enterprise Linux these items are an attempt to match XFS performance with ext3. These items were culled from a number of sources. Will they be effective for achieving the performance

Hi, I have gone thought he painful operation of registering just to edit one page then I found out i have to also get on this mailing list to get permission... Why can't the wiki page display that I have no permission to edit? and also why can't edits be sent to a moderation queue for approval? Anyways this is my request to edit http://wiki.centos.org/HowTos/Disk_Optimization page as it

Dear all, In "HowTos/Disk_Optimization", the calculated value of stride size and stripe width appears to have the "K" suffix incorrectly appended to them. Eg: * (64K/4K) = 16K * (3*16K) = 48K * (16K+16K) = 32K The values provided on the mkfs.ext3 command line however, do drop the "K" suffix. I'm no expert on RAID, but the "K" suffixes

Hello, I understand the need for a proper stride setting when formatting a filesystem on a RAID device. However, is there any problem in using a stride setting when formatting a filesystem on a regular non-RAID, non-SSD, just plain-vanilla-single-disk block device? I'm sure there isn't any benefit to it, but I'm curious if there is any harm. The reason I ask is I'm looking at

Hello all, I have yesterday after some typos, sent my ext3 RAID5 array to the void... I want to recreate it now, but I read on http://wiki.centos.org/HowTos/Disk_Optimization that you can optimize the filesystem on top of the RAID. Will this wiki article be exactly the same for XFS? Is it worth the trouble to also create an LVM volume on the RAID array? Regards, Coert

I have two contexts and there I have some sip clients and some iax clients, in the sip clients a have extentions like, 20, 21, 22, 23, etc; in the iax clients I have some extentions like 2000, 2001, 2002, 2003, etc. My extention is 2003 when I make a call the manager program show me that the extention 20 was originating the call (in red, and show my name/extention)! When I make a call to

Hello, We are looking to adjust the font size of the axis annotation on the graph that results from use of the metaplot() function. Metaplot seems to respond to cex and cex.lab to change those graphical parameters, but it doesn't respond to cex.axis. Is there a way to work around this by creating a customized x-axis, and if so, how? Thanks for all your help. Syntax is below. Best, Dawn

We are writing a program using the manager for * for our receptionist to use once the system go live. If anyone is interested in helping us with testing please let me know. We are designing it for a touch screen monitor for her to do transfers, see whose on the phone and a few other features. Its in the development stage and has bugs. but I think its gonna be really good. If your interested

So I have been playing with a RAID 10 f2 ( 2 disks far layout) setup...thanks for all of the advice..Now I am playing with the format and want to make sure I have it setup the best that I can, my raid was built using the raid 10 option with 2 disks with the layout=far, chunk size 512....now I read all of the docs I could find about format and stride and stripe size and this is what i came up

I have looked all over the site(s) for help. But heres the problem. Im missing something. In coming works fine from FreeWorld via IAX.

What is the state of speex support in asterisk? I saw the codec seems to be there. Can speex be used on IAX2 links? Is there much work still to be done? many thanks, --J.

Fixed. Thanks.

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: >>

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

Hi Evan, In -relocation-model=static mode, those tests are now getting code like this leaq A, %rsi movss %xmm0, (%rsi,%rdx,4) instead of this: movss %xmm0, A(,%rdx,4) This is specifically what these tests were written to catch :-). Running them with -relocation-model=pic is hiding the real bug. Dan On Feb 11, 2008, at 11:22 PM, Evan Cheng wrote: > Fixed.

Fixed. However, I wonder if we are doing the right / smart codegen for static codegen. AMD64 ABI document seems to indicate rip relative addressing should be used even in this case (see page 38). You know about about Linux addressing mode than I do. Please check. Thanks, Evan On Feb 12, 2008, at 10:10 AM, Dan Gohman wrote: > Hi Evan, > > In -relocation-model=static mode, those

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
