Mdadm does not seem to support growing an array from level 1 to level 10.
I have two disks in RAID 1. I want to add two new disks and convert the array to a four disk RAID 10 array.
My current strategy:
Make good backup. Create a degraded 4 disk RAID ...

2) Mount the raid10 & rsync the RAID 1 with the new RAID 10.
With linux softraid you can make a RAID 10 array with only two disks.

With either scenario, except with raid 10 if you happen to lose the wrong 2 drives then you'll have a real occur over enough time for the raid to rebuild between failures.

You can increase the performance of your setup.
While the article says it is for SQL, it is really for any database running on top of RAID with Windows Server 2003 or earlier.

Hi,
we have a RAID 10 datastore (4x SAS) on an IBM x3650M2 server but our VMWare ESX 4.xx server does not see this datastore.
Does anybody knows whats wrong there?

Put it into a RAID 10 and see with the workload.......
Unless you're doing something that is very sensitive to speed issues I wouldn't worry about breaking things into small arrays or anything like that .

Just simple disks.
When I read (quick overview, 5 sec.) the webpage on "RAID Reconstructor" right, you'd put these three disks into a computer with no RAID-controller attached.

I have a Linux software raid 10 setup consisting of 5 RAID 1s (Two drives per mirrored setup) and a RAID 0 across all 5 RAID 1 pairs. To test that none of the drives were going to fail quickly under load I used badblocks across the RAID 0 with a destructive...

It is, if you have to test the RAID reliability you must tag as failed a drive, a disk, not to destroy.
It will release the hangy RAID.
Maybe you need ask to the kernel to remove the faulty drive .

I recently purchased a SansDigital external RAID enclosure for my WHS. I have 4 drives I was going to use in it. Should I use the disks individually and let WHS handle the duplication or should I use the software RAID to do RAID 10 or RAID 5?

With RAID 10, you have a 25I wouldn't recommend RAID5 for data that you really want protected.
That you could lose 2 disks, but you lose half of your storage space .
