Hi,

thanks...what you said is exactly what my tests showed. If the parity and DP are big enough you can run disks with different size in a raidgroup and use the whole size but this does not work if a small disk becomes replaced via a bigger one.

thanks and best regards

Jochen

Sorry Adam, I used the wrong verbiage.

I meant when the disk is added...not replaced.

For now, ONTAP does indeed right-size a disk down to the size of the disk that it is replacing.

thanks.

No. You can't replace disks in an aggregate that way. If you do, they will sized down to the size of the disk they replaced.

Hi toasters,

currently i am testing with my simulator and searching for a way to do the following:

• have a raidgroup with 5 disks
• the two parity-disks plus one data-disk are 100 MB (net)
• two other data-disks are 35 MB (net)

I want to replace the 35MB-disks with bigger ones, but everything i tried left the "new" disk in the raidgroup with a used size of 35MB.

Is there a way to replace a small disk with a bigger one and use the complete size of the disk without destroying the whole raidgroup?

Regards and thanks in advance

Jochen
