Warning: This type of storage space should be avoided for critical data due to its lack of fault tolerance and increased risk of drive failure. on 09 Apr 2010 at 1:20 pm2Graham Booker vlhorton, No, I haven't but I did in looking at your suggestion.

Impressive work. I recently added a 1.5 TB drive to my existing array (3 x 1.5). Thanks. Of course the costs go up with more ports. here

In the field labeled Storage space size change the amount to the number reflected in the Total pool capacity row. I'm guessing the bottleneck is the HDD? - Would a rebuild (if called for in the future) take this long?

Hadn't considered XFS before, but it appears to have some big performance benefits for large files. As someone who is not willing to spend the money on a hardware RAID solution, I wanted to determine the performance implications of choosing between the cheap RAID 0 (striping) and If you have any questions, please feel free to discuss them in the Windows 8 forum. What Is Raid Technology Seems like it says it's good, but it's bad.

This article covers the following RAID levels: RAID 0 - striping RAID 1 - mirroring RAID 5 - striping with parity RAID 6 - striping with double parity RAID 10 - Raid 5 Explained Ideal use RAID 0 is ideal for non-critical storage of data that have to be read/written at a high speed, such as on an image retouching or video editing station. A smart raid 1 should be able to read a file from both disks simultaneously, only the write part is not accelerated. You probably want RAID 5, and/or JBOD.If, however, you're planning on serving video to more than a handful of stations simultaneously, you may need to consider performance.

I am considering a similar partition scheme, but with ext4 or btrfs. Raid Level 2 RAID 1: Not sure. Reply Bruno says: July 6, 2011 at 2:51 pm Interessting test but you have to watch out for those Seagate drives. At least all the ones I have seen weren't. 3ware makes a fine hardware raid card that have between 2 and 16 or more SATA ports on them.

  1. If I lose one of the harddrives; that's life.
  2. Sorry if this is the wrong place to post since it's technically not a raid5->raid6 problem (I've been reading this blog for a while now).
  3. Good (and well supported) RAID products cost good money too, and for most of us it's just not worth doing - better to use software RAID, buy more RAM, and pocket
  4. I've come up with two options to do this upgrade: 1.
  5. Get something that supports multiple volumes and at least 8 disks.

Raid 10 (1+0) through the Windows driver - if it were possible, would gives the user MiRRoRing (or DATA Retension) as well as SPeed advantages through SPANning? In fact, you can take a single RAID 1 disk and put just the one disk in another machine and it should read just fine (although it will report that it's Raid Configuration Calculator

You are a true Technically experienced genius unlike to most Book Worms and High Shouts in IT Blogs… WELL DONE !! Worst case, you lose the time spent ripping the media. RAID 1 needs nothing special it does not change your primary disc. After manually assembling and mounting everything works as normal.

Glad it was useful for you. Which Rotation Speed Is Not A Typical Spindle Rotation Speed For Magnetic Hard Drives? Thanks for helping, rman [permalink][hide] Re: Converting RAID5 to RAID6 and other shape changing in md/raid (22 February 2010, 20:56 UTC) You have found a bug! How do you know when it's finished?It should have  never left the OS.  Why was the server even restarted?It should not be in the BIOS, it should be left as is

And finally I have a raid on 3 750gb partitions using 500gb of each, and I can grow that to size=max, and I have my 3x750gb RAID.

Here's my unRAID server [coppit.org], built for $400 plus the drives. md/raid5 allows this reshaping to happen while the array is live. For example, say I have 3x500gb drives in RAID 5 and over time replace all of them with 1TB drives. Raid Performance Comparison When you are ready, click on the Create storage space button and the new parity storage space will be created as shown below.

Therefore, if you have four 120 gigabyte drives and create a parity storage space, the total usable space will be 360 gigabytes (3 * 160GB) with the fourth drive being used I currently have a 6 Drive Raid 5 consisting of 5x1TB, and a 1TB LVM (2x320GB, and 1x500GB (OS included in extra space)). These better cards also can be linked together (i.e. Kevin Reply kmwoley says: November 30, -0001 at 12:00 am Thanks for the feedback.

a- fail one of the RAID1 partitions b- create a degraded 3 partition RAID5 (ie. 2 partitions present, and one missing) using the "failed" one and the new one c- copy To access the Startup Settings boot menu in Windows 8, you need to do so via the Advanced Startup options menu. I get 10-16MB/sec transfer. That is why you use Time Machine for the data residing on the internal drive but of course the same also applies to the data that will be stored on those

However you just need mdadm-3.1.1 or newer, linux kernel 2.6.32 or newer and then mdadm --grow /dev/mdXX --level raid5 --backup /some/file/not/on/the/array It will take a while rearranging all the data, but For some reason, Microsoft decided to disable access to the drive when it runs out of space instead of just reporting it full. Windows 7 and below don't because the method of setting up RAID in these versions through the "Disk Management" utility with their "Dynamic Disks" doesn't. (So far as I know).
