Hi all,

I was today logged-in on our NetApp:

system:system:system_model:FAS2240-4

system:system:ontap_version:NetApp Release 8.2P2 7-Mode: Sat Jul 20 20:31:47 PDT 2013

On one of the filers I saw regular this error message:

On the other I haven't saw this message. I'm pretty sure the setup of the disks aren't done that well, but now it is like it is 😞

I'm trying to figure how you got yourself into this pickle.. You got a little mess on your hands..

It looks like you have three types of disk in this filer, SSD, SAS and SATA.

You have aggr0 as raid-4, with such a small system, you might have wanted to spec this filer differently

You essentially have only spare of each drive and you aren't balanced properly across the cluster.    You should slap your netapp sales rep for specing this system like this.

Hi,

that's right. SSD, SAS, SATA.

As far as I know is the SSD used as fast cache. And then there are are dedicated aggregates for SATA and SAS.

The Setup isn't balanced at all, it is more a ACTIVE/PASSIVE setup.

Problem is that I'm not that familiar with NetApp and the guy who did it, isn't here anymore.

Anything you could recommend to change?

You're stuck my man.  First, you need to zero the spares (disk zero spares)

Now, I know why the guy who set this up left, he has no clue what he was doing.

I'm counting

18 x sata

6 ssd's

That looks like it's in your internal filer

then you added a shelf for SAS and you have 12 SAS drives

What i would do is roll up aggr0 into the sas aggr, (moving root volume , etc..)

Destroy aggr0, and zero spares, and then move one spare to the other node


Therefore, aggr0 on the other side is raid4 with one spare. (should be using raid-dp, but your stuck)

Also you are burning SSD drives with no use, maybe try to swap two of them out, since you only need one spare for your flashpool.

But, i would call netapp support to verify, don't take just my word for it
