Hello,
i have an 8 port sata-controller and i don't want to spend the money for 8 x
750 GB Sata Disks
right now. I'm thinking about an optimal way of building a growing raidz-pool
without loosing
any data.
As far as i know there are two ways to achieve this:
- Adding 750 GB Disks from time to ti
You could estimate how long it will take for ZFS to get the feature you need,
and then buy enough space so that you don't run out before then.
Alternatively, Linux mdadm DOES support growing a RAID5 array with devices, so
you could use that instead.

Pardon me for jumping into a group I just joined, but I sense you are
asking sort of a "philosophy of buying" question, and I have a different

Mirroring is the simplest way to expand in size and performance.

Why did you choose to deploy the database on ZFS ?

I have a 26tb pool that will be upgraded to 39tb in the next couple of months.

I believe you got this wrong. You should have given ZFS the whole disk -

What brand is your 8 port satacontroller? I want one sata controller too, but
heard that Solaris is picky about the model. All controllers doesnt work. Your
