Creating new ZFS pool for ISCSI in 9.10

[mst]

Is there any guide for creating a new ZFS pool for iscsi vmware 6.5? I have 8 of 2TB drive and wonder what setting should be for new ZFS

 

[mst]

What is best option from these:

• Stripe: requires at least one disk
• Mirror: requires at least two disks
• RAIDZ1: requires at least three disks
• RAIDZ2: requires at least four disks
• RAIDZ3: requires at least five disks

You might check the User Guide at the top of the page...

Also, why are you still on 9.10?

 

[mst]

When I choose Mirror it gives me only 3.63 TB and when I choose RaidZ2 it gives me 7.27 TB - should I create 2 x Mirror volumes? That does not make any sense - why not use all 8 in one volume in mirror

 

[kdragon75]

For VMware, you should run mirrors. That means you only get half the space but it's much faster.

 

[mst]

OK, get it creating Volume with Mirror - ehhhh any guide how to create ISCSI for that volume.

that part is done, now Create VOLUME so should I now create zvol or dataset for my ISCSI ?

 

[kdragon75]

Its all in there. Keep reading.

I have stuck in creating volume "Mirror" and if I have 8 disks (2TB) each I should have about 8TB in Mirror - correct? I have tried many times, deleting-wipeing hard drives and still no luck. Now I even have 1.82TB using all 8 x 2TB hard drives each

 

[mst]

this is crazy, its either 9.10 stable bug or something else, I have one more separate volume with 3TB hdds and that is detected and in the mirror like it should be. Should I install 11.2 STABLE version and try then?

Can you send a screenshot of how your making the pool?

 

[mst]

I have created one Volume by adding two drive 2TB+2TB and in that way it works, choosing all 8 gave me only 1.82TB

 

[kdragon75]

I sounds like you trying to setup an 8 way mirror. 2x2TBx4 is what you want. TRo verify the pool was created correctly, please provide the output from zpool list -v
You not encountering bugs, you just are not understanding the UI.

 

[kdragon75]

Again, is there a reason that your running 9.10 instead of 11.1? there have been some major improvements.

I think I should be good in regards these 2TB drives in Mirror:

That looks perfect. Now just follow the user guide on setting up iSCSI.

 

[mst]

I have that already set up .... the next step would be upgrading freenas from 9.10 to 11.2

Why do you want to update to a beta?
