Problem creating raid

[Slyistheman]

I have a Dell PE T620 Server with a IBM M1015 flashed to IT mode. I have 12 hard drives and FreeNas sees all of the 12 drives but if I want to create a Raid 10 setup it only shows 10 available drives. not 12. The same problem also if I want to create a RaidZ1 and Raid Z2. Is there a max hard drive of 10 drives?

Ditch the wizard and configure it the normal way.

Are all the hdd the same size? I suspect the 2 missing are a different size. To create a pool like that use the manual configuration option in the GUI.

It looks like da8 and da10 are missing. Of those two, da10 is visible underneath the window and appears to be the same size.

Ahhh yes you're more observant than me on this one.

I'm wondering if maybe it is enforcing some sort of rule about vdev width, but that wouldn't make sense for a "RAID10" where you're just creating sets of mirror vdevs and the width is always two.

I see da8 tucked behind there as well and it's reasonable to assume that it's also a 320GB WD drive.

Maybe the wizard just bugs out when it's asked to handle > 10 drives, let me see if it does that on my 12-drive testbed.

Edit: Nope.

I'm betting the WebGUI just runs out of space to show more drives. :P

 

[Slyistheman]

All the hard drives are all the same.. 320GB weird eh? If I removed 2 hard drives and replace them with 2 ssd and I try to create a raid 10 with the 10 drives then it sees only 8 drives now.. how messed up is that lol

 

[Slyistheman]

How do I create raid 10 in manual setup?

 

[jgreco]

First, note that RAID10 is horrible terminology because ZFS has no such thing.

When you create a mirror vdev (two hard drives mirrored against each other), you can then add another mirror vdev to that first one, and ZFS will intelligently load balance between them. People often mistake the load balancing for "RAID 0" but it isn't. ZFS will do something similar to striping between the vdevs if all things are equal, but often they're not.

So you can just add two disks at a time, creating new mirror vdevs as you go, to an existing pool, and you end up with "RAID10" - a bunch of mirror vdevs that are all part of a single pool, and ZFS load balancing between them.

 

[Slyistheman]

I created a bunch of mirror disks like you suggested and how am I suppose to create one dataset with all drives? I would like to have one large amount of hard drive space..

 

[pirateghost]

You should have created ONE pool, and added each mirror to the pool

 

[Slyistheman]

I might need a push in the right direction. I created a pool and now I am wondering how to add each mirror to the pool

I found how... thanks for your help

 

[pirateghost]

When you create each vdev after the first, you select 'extend volume'?
