Newbie to unraid (but not truenas et al.): problem configuring zfs raid array

Featured Replies

As the subject says I'm new to unraid, but have managed many other storage systems succesfully before.

I have just received a LincStation N2 which comes with unraid on year subscription. I'm currently running on the trial set up.

Upgraded unraid to 7.1.4, which is the latest at the moment.

I have inserted four nvme drives, two Crucial P3 and two Orico o7000, each 2TB.

I don't need caching but simple want the two Crucials in a zfs mirror so I can use if for nfs shares, and the two Oricos also in a zfs mirror, but it will get smb shares.

I created two new pools, with zfs in mirror, but the array won't start. It won't see the pool devices, and even in the console a zpool status doesn't show any zfs pools.

I'm obviously doing something wrong, but don't have a clue. It's a simple setup, two zfs mirror pools where I can build my shares on.

Any help is appreciated.

Regards,

Albert

Here is the diagnostics file. I messed up a bit. Tried zpool import which gave weird results.

So I deleted the new pools and recreated them again.

So I again have two pool devices, crucial and orico, and am stuck.

Thanks for your help so far,

I assume some of the devices were assigned to the array before, and that they don't have any important data and can be formatted? Is this correct?

  • Author

Yes, that's the easy bit. It's a new set up, device can be formatted, there is no need to retain data.

  • Community Expert

They appear to be assigned to the new pools, but because they have previous pools, you need to click "erase pool" first, after that, select the filesystem and profile you want, start the array, and format the new pools, any issues post new diags.

Under Arrray Operation it reads: Stopped. No devices, No array devices have been assigned.

You cannot have the array without any assigned devices, change the array slots to 0 or none.

  • Author

JorgeB, you're the man!

Changed the array slots to none and bingo, I can start the array now.

Muchos gracias!
