How to copy pool to new disks and use on a new TN13 server

[profwalken]

Hi,
I have a small TN13 server with only 2*2TB disks in mirror , my goal is to change to a more powerfull server and copy all the pool on a mirrored 2*2TB new disks.

How is the best way to do this ? just take one drive from old server pool and connecte it to new server and then rebuild mirror with one new drive ? and once is ended with the first disk restart with the second one ?

Easiest way, imo, is simpl;y more the current disks to the new server & import the pool. Also, could save config, move disks to new server, then upload config. Copies all setting/etc. If you are looking to end up with 2 servers, given the small amount of data, assuming GB network, could set up new server & pool then use a network connection to copy the files, even Windows. Good luck.

Hi John,
Thanks for your advice, my goal is to change and increase server hardware power and copy content of pool, on new disks, as the existing used in prod have 7 years .
Actually server A is a I3, 8GB and mirror of 2*2TB
Goal is Server B HP with Xeon E3-1246 with 32Gb ECC RAM and 2*2TB Seagate ironwolf and a mirrored boot too, on 120 GB SSDs.

I have restored a config file to setup new server as the old one, now I need to transfer most impotant users Data.

zfs send and receive via SSH ... you can even do it in the UI. Look for Replication Tasks.

So if i connect old disks on new server I will have instantly pool , but how to replicate pool on these new disks.
At the end I want old pool copied on new disks, that's all
Is my initial idea not enough good ?

This seems too complicated to me as i'm not enough sure of what to set each side to get the result

if you move the disks to the new machine temporarily you can still use zfs send and receive. This is the fastest and most consistent way. The data is guaranteed correct when the job is finished.

ZFS send and receive, is this command lines or choice to apply in GUI console ?

 

[Patrick M. Hausen]

For a one time operation it's command line. You can define a local replication task, though, and remove it once it's run to completion the first time.

I've no idea what could be a command line to do this , so it will be with my modest knowledge in GUI
