Importing existing Vdev/Storage pools

[3oin]

Will it be possible to import an existing storage pool from another truenas (scale) build? Or do you need to wipe all the data and start again? (I figure you won't be able to do this in beta but will it be available after 1.0?) Thanks.

also would love to know as im running trunas but plan to convert to hexos but would rather not transfer data  off drives to refill them again

Hi there! This is something we’ve gotten a lot of questions about and we will explore the possibility of “adopting” an existing TrueNAS installation or pool at a later stage.

I would love to know what is the end result of this.

As FreeNas/truenas slowly change it has been difficult to keep up with the updates.

If not possible to change or bring existing storage, would a form of backup system be created instead?

I successfully imported my truenas pools.

before doing the hard drive configuration in deck.hexos.com navigate to the ip of your server and import pools in truenas

then go complete the harrddrive config in the deck. it says it deletes the drives but didnt for my configuration atleast.

4x 16tb drives and 2 2tb ssds so it paired everything properly but id attempt at your own risk.

I know I am maybe a couple of months late to the party and thank you for this post.  I was able to import the pools but did you figure out how to get HexOS to recognize the datasets in those pools for the purpose of configuring the SMB share?

Addendum: I dumb. I was able to just add the shares in the TrueNAS layer and then HexOS worked just fine.

Hey guys, I'm looking to do something similar - So during initial hexos setup, you drop down to the underlying truenas scale interface, use that to import your old true nas drives (vdevs/pools), and then return to the hexos setup, where it claims to delete your drives(!), but doesn't really?

That is the expected behavior, yes. But please be advised that because this is still in beta things can be wonky. Backup your data, first.
