Subject: Expanding array by changing disks (one by one)
Date: Thu, 14 Apr 2005 12:11:20 +0200	[thread overview]
Message-ID: <425E41C8.7050704@apartia.fr> (raw)

Hello,

We are in the process of increasing the size our RAID Arrays as our 
storage needs increase.

I've got 2 solutions for this:

- Copy the data over a new array and replace the disks

- Replace each disk (one after the other(after resync)) of the existing 
array with a bigger one.

Start:
    - Array is ok
- Remove 1 disk
    - Array is degraded
- Add a bigger disk
    - Resync
- Remove another disk
    - Array is degraded
- Add a bigger disk
    - Resync
.....

Would this be the 'state of the art' way ?

Will the filesystem cope with it?

Is my mind completely broken?

Thanks for your help.

Laurent
