You can identify this problem by looking at the output of "cat /proc/mdstat". This offers higher performance than RAID-3 but at much higher cost.What can I use to build a RAID array?Today we are spoilt for choice. What type depends on the flavor of Windows: Windows XP allows spanned volumes (one volume over two or more disks), aka JBOD. In their June 1988 paper "A Case for Redundant Arrays of Inexpensive Disks (RAID)", presented at the SIGMOD conference, they argued that the top performing mainframe disk drives of the time http://darrenburnhill.com/how-to/need-some-help-on-hard-drives-set-up-as-raid.html
This makes larger RAID groups more practical, especially for high-availability systems, as large-capacity drives take longer to restore.

Otherwise, stick to software.Prepare your hardwareTo ensure the best RAID performance, use identical drives with the same firmware. However, if any of the hard drives in the RAID array dies, you'll lose your data. check my blog
It is also suitable for small servers in which only two data drives will be used. As it always stripes over top-level vdevs, it supports equivalents of the 1+0, 5+0, and 6+0 nested RAID levels (as well as striped triple-parity sets) but not other nested combinations. Most commonly used are SSD and mechanical hard drives.RAID requires that at least two drives be used but the upper limit is dependent on the type of RAID and your hardware’s The Rampage V Extreme's SATA and SATA Express ports connected to Intel's X99 chipset support RAID 0, 1, 5 and 10 modes.What kinds of RAID are there?I know of 9 different

This is supported in Linux, OS X as well as Windows and has the advantage that a single drive failure has no impact on the data of the second disk or For example, Windows XP Professional supports RAID level 0, in addition to spanning multiple drives, but only if using dynamic disks and volumes.

The probability of two failures in the same 10-hour period was twice as large as predicted by an exponential distribution. Unrecoverable read errors during rebuild Unrecoverable read errors (URE) present as That means it requires at least 4 drives and can withstand 2 drives dying simultaneously. http://darrenburnhill.com/how-to/how-to-setup-lan-to-linux-box.html When you add a third disk for Time Machine you can still do it all with a 4-disk enclosure, instead of having to buy a more expensive 5-drive system.
If you’re using FakeRAID, the motherboard’s RAID utility should warn you before it wipes partition tables and the filesystems on them.In your operating system, you’ll need to have elevated permissions to How To Setup Raid 5 mdadm checks that the components do form a bona fide array, and can, on request, fiddle superblock information so as to assemble a faulty array.

If your system has RAID support, you should have a file called /proc/mdstat. Current recommendations are to use metadata version 1.2 except when creating a boot partition, in which case use version 1.0 metadata and RAID-1.

Thus, for large writes, you may see lower overhead by having fairly large chunks, whereas arrays that are primarily holding small files may benefit more from a smaller chunk size. Both hard disks and SSDs can be used, and while it's advised that matching drives are used in a single array for best performance, it's not strictly required.This article focuses on Text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply. navigate here See the section on special options to mke2fs before formatting the filesystem.
Select all the disks you want in the array and click Create pool . There is no overhead caused by parity controls. ZFS, GPFS or Btrfs) A layer that sits above any file system and provides parity protection to user data (e.g. Hardware just doesn't support that.
NOTE: A work-around to upgrade metadata from version 0.90 to 1.0 is contained in the section RAID superblock formats. Enable Intel RAID Technology. How can you have RAID 1+0 with two disks? The persistent superblocks solve these problems.
