Re: [CentOS-docs] Some questions: Release Notes CentOS 5.6

Hello
A couple of days ago, I did the Spanish translation for ReleaseNotes
CentOS 5.6
and I have some questions
Right now, in the Spanish version we are using nice icons for Notes.
Would you like the same in the English and other translated versions ?
(I know that is not important, just looks nice ;-) )
As long as we are consistent in the wiki and we do not make it look as
colored as a parrot, I like this idea.
On many places we mention packages names or file names. I suggest
use {{{typewriter}} style for this, to better reading/understand.
My wiki-foo is weak. Can you provide more details please, so that I do
not go hunting for documentation ?
Some time ago, we talk about some common parts in all the translated
versions.
And we started to use marks #begin- #end- Right now, we
don't have
this marks for the Translations subtitle in the original version. We
should use
I think.
You cannot do that because the translations section must include [*]
the language names expressed in the language of the translation. For
instance in the Romanian release notes I would use
* [:Manuals/ReleaseNotes/CentOS5.6/Spanish:Spaniola] (Español) -
[:HardyBeltran:Hardy Beltran]
while in the Spanish version you should use
* [:Manuals/ReleaseNotes/CentOS5.6/Romanian:Rumano] (Romana) -
[:HardyBeltran:Hardy Beltran]
[*] Unless we decide to not do that
By the way, I need help to use 'Include macro', all my tries were
unsuccessful
Get inspiration from the Romanian and French translations. I am lazy so
in step 1 I bookmarked the lists of packages for the English version and
in step 2 I included the lists as such ( using bookmarks ) in those two
translations. You can simply copy/paste the relevant lines.

This is where I'm getting confused. I had been reading up on mdadm, torn between using RAID 5/6 for the ability to grow the array with more disks and RAID 10 for better IOPS. The man pages itself says that Currently supported growth options include changing the active size of component devices and changing the number of active devices in RAID levels 1/4/5/6, Along with other internet sources seems to imply that growing RAID 0 is not supported, and by therefore by extension neither is RAID 10. Furthermore, I read on Neil Brown's blog that reshaping RAID 10 was a planned but not implemented feature. Is the difference here between using mdadm to directly create a RAID 10 vs manually layering on RAID 0 on RAID 1 devices? Or is the expansion here limited to replacing the existing components drive with larger ones, e.g. replacing four 1TB drives with four 2TB drives so going from a 2TB to 4TB array? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] 40TB File System Recommendations
Thank you everyone for the advice and great information. From what I am gathering XFS is the way to go. A couple more questions. What partitioning utility is suggested? parted and fdisk do not seem to be doing the job. Raid Level. I am considering moving away from the raid6 due to possible write performance issues. The array is 22 disks. I am not opposed to going with raid10 but I am looking for a good balance of performance/capacity. Hardware or software raid.

Is there an advantage either way on such a large array? Doesn't that depend on what sort of backup solution you're planning, and the level of criticalness of the backups saved? Some say that for more serious raid solutions, hardware is the way to go, while software raids are sort of a middle-road. Me, I usually go with software raid. I've had one too many hardware raid failures where I haven't been able to restore the data contained. With software raid a restore has always worked fine for me, especially broken raids in Windows. While raid in Windows isn't overly performance-inclined, I've come to appreciate the software ditto in linux - both performance and stability is top-notch IMHO.

This requires the CentOS team to build these packages as one off builds with a special dist set in our build system. Sometimes we get it wrong as our updates are built and tested in an automated fashion then we check them by hand and deploy. If dist was hard coded, then we would have the correct one. We are aware of the older released dist tag issues. However, there is NO WAY to fix it until an upstream update occurs.

I also have a few 5900 rpm Seagate ST32000542AS drives, but not currently in raids. They don't spin down, so I'm sure they would be fine in a raid. The biggest issue isn't the spindown.

In a nutshell, TLER (Time-Limited Error Recovery; see https://secure.wikimedia.org/wikipedia/en/wiki/TLER ) allows the drive to not try to recover soft errors quite as long. The error recovery time can cause the drive to drop out of RAID sets and be marked as faulted. Just because they are so tiny on the outside, 2.5 inch drives like the Seagate Constellation and WD Raptors are great. Unfortunately, the don't come any larger than 1TB, so I use them in special situations.

Yes, I'm aware of that and it's the reason I have to replace drives developing reallocated sectors: they get dropped by my 3ware controllers. There's a penalty for using cheap drives, but there's also a benefit from the low heat and power savings. To me, drives and power supplies are a consumable item - something you're going to have to replace from time to time. I'm used to it since I service computers for a living. I've seen enterprise drives fail too, although probably not as often. By the way, I'm seeing too many ppl with failing SSD's to start relying on those yet.

Could you or anybody else please share what's the trick to achieving this? You can't expand a mdraid raid0. I believe you can expand a mdraid raid10,5,6, but not raid0. If you want to use separate raid1 devices instead of mdraid's raid10 implementation then use LVM, add them to a VG then stripe the LVs across the different PVs. The only problem with that is restriping existing LVs across new PVs is difficult to the point that it is often better to create new LVs with the proper striping. You can do it though using 'lvresize' to change the stripe width, but it won't give a linear striping for existing data and the LV will eventually fill the first PVs causing all data to only be written to the last PV. I often find it handy to have a backup raid1 disk on the system that's big enough to hold the contents of the largest LV, then dump the production LV to the backup, blow away the production, recreate with the new stripe size, then restore the data back. This backup volume could be an iSCSI volume exported from another server that does have the capacity if there isn't any in the host. -Ross ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thx, JD We're running an nginx frontend on SSDs right now - don't bother with things like JFFS2, they're intended for SoC distros that have raw flash chips memory-mapped to the controller. Most of that intelligence is handled by the SSD controller. CentOS 5 does not have TRIM capability - I'm not sure if CentOS 6 will or not, though. The most important part of setting up SSDs on a server is to mount all the filesystems with the noatime option - that reduces the filesystem writes tremendously. Having a good controller is equally important - don't run them on a $25 SATA card. And, since memory (up to a point) is cheaper than SSDs, fill the box with memory sticks. Keep a swap partition, but put in far more memory than you think you will need, and that way you won't hit swap unless the excrement really hits the air mover.
