Resize Raid?
« on: March 02, 2010, 10:24:28 AM »

Hey All,

New to the board here. I have a question. Currently i have 2 500G hard drives in Raid one in my DNS-323. I am running out of space and want to add in two largers drives without losing any of my data. If i put in one larger drive, let the raid rebuild on that, then swap out the other smaller driver, when the raid is redone, would i have the full space of the newer larger drives?

Thx.

No you wouldn't.

The only way to do what you want (without hacking the DNS-323 and a lot of fiddling with linux) is to backup your data, remove the existing drives and install the new ones, create the new array and then restore your data.

You might be able to skip the backup step by mounting one of the original drives in a PC running linux or Windows and the ext2ifs file system driver, but, you'd need to ask yourself first - do I value this data?  What will I do if something goes wrong?

RAID1 is for disk redundancy - NOT data backup - don't confuse the two.
