Single Disc NAS - Replace the Disc!

TrueNAS General
1

Hi All

I have a Lenovo mini-PC NAS.

The Truenas OS is on an NVME, and the data is stored on a single 2TB SSD.

I want to upgrade the 2TB SSD to a larger one.

The data on the mini-PC 2TB SSD is a duplicate of one folder on my main NAS

What I need guidance on is how do I “remove” the SSD and “install” the new drive?

Do I use - Storage/Devices/Details for/OFFLINE - the SSD, replace the SSD with the new drive and then restart, and copy the data from the main NAS
OR
Do I use - Storage/Devices/Disk Info/REPLACE - the SSD, replace the SSD with the new drive and then restart, and copy the data from the main NAS?

I want to retain the folder and file permissions etc without having to go through the process of ACLs etc.

Any thoughts on the “right” way to do this disk swap on a single disk NAS?

Thank you for your input.

Install a new drive, replace the old drive with the new, when complete remove the old drive. All the data will be moved over in this process.

Thanks Dan…
Only problem is that there’s only one SATA and power connection…

I’ll have to remove the existing drive when I install the new one…

I don’t know how Truenas will “react” to the removal of the data drive… that’s why I want to know the “right” way to remove the existing drive…

Thanks again.

Get a SATA-to-USB adapter. Install the new drive, put the old drive in the adapter, power on, and “replace” the old drive from GUI.
USB is normally advised against for data drives, but here you have no choice: You need to have both drives, old and new, attached while replacing.

There is no right way to remove the one drive of a single-drive pool. The system won’t let you do it without taking the whole pool offline. You could export the pool and create a new pool on the new drive, then replicate the data to that new pool. But the better answer is what @etorix suggested.

Thank you for your reply. I will explore that option.
