similar to: mdadm Linux Raid 10: is it 0+1 or 1+0?

Hi, Can someone please assist met with some software RAID 1+0 setup instructions? I have searched the web, but couldn't find any. I found a lot of RAID 10 setup instructions, but it doesn't help me. -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Has anyone posted an up to date hardware review lately? It seems clear that a RAID6 server with 300GB CHEETAH 15K.5 SAS drives will trump a P3 with a 30GB IDE drive, however, not everyone will spend the money required for the high end unit, I'm looking to build a new server & trying to make best use of funds (aren't we all). TIA

Hi All. I have a server which uses RAID10 made of 4 partitions for / and boots from it. It looks like so: mdadm -D /dev/md1 /dev/md1: Version : 00.90 Creation Time : Mon Apr 27 09:25:05 2009 Raid Level : raid10 Array Size : 973827968 (928.71 GiB 997.20 GB) Used Dev Size : 486913984 (464.36 GiB 498.60 GB) Raid Devices : 4 Total Devices : 4 Preferred Minor : 1

Greetings- I'm about to embark on a new installation of Centos 6 x64 on 4x SATA HDDs. The plan is to use RAID-10 as a nice combo between data security (RAID1) and speed (RAID0). However, I'm finding either a lack of raw information on the topic, or I'm having a mental issue preventing the osmosis of the implementation into my brain. Option #1: My understanding of RAID10 using 4

How can I verify the read speed of a btrfs raid0 pair in archlinux.? I assume raid0 means striped activity in a paralleled mode at lease similar to raid0 in mdadm. How can I measure the btrfs read speed since it is copy-on-write which is not the norm in mdadm raid0.? Perhaps I cannot use the same approach in btrfs to determine the performance. Secondly, I see a methodology for raid10 using

I have been reading lots of stuff but trying to find out if a raid10 2drive setup is any better/worse than a normal raid 1 setup....I have to 1Tb drives for my data and a seperate system drive, I am only interested in doing raid on my data... So i setup my initial test like this.... mdadm -v --create /dev/md0 --chunk 1024 --level=raid10 --raid-devices=2 /dev/sdb1 /dev/sdc1 I have also read

Hello... I have a server with 4 x SCSI drives and I would like to install Centos 4 (or 5) onto a software RAID 10 array. Do you know if this is possible? I noticed that under the Centos 4.92 beta, RAID 5 is an option but for some reason RAID 10 is not listed. There does appear to be a RAID 10 module.... /lib/modules/2.6.9-42.0.8.ELsmp/kernel/drivers/md/raid10.ko More info I found here:

So still coming up to speed with mdadm and I notice this morning one of my servers acting sluggish...so when I looked at the mdadm raid device I see this: mdadm --detail /dev/md0 /dev/md0: Version : 0.90 Creation Time : Mon Sep 27 22:47:44 2010 Raid Level : raid10 Array Size : 976759808 (931.51 GiB 1000.20 GB) Used Dev Size : 976759808 (931.51 GiB 1000.20 GB) Raid

I just created a 4 drive mdadm --level=raid10 on a centos 4.8-ish system here, and shortly thereafter remembreed I hadn't updated it in a while, so i ran yum update... while installing/updating stuff, got these errors: Installing: kernel ####################### [14/69] raid level raid10 (in /proc/mdstat) not recognized ...
