How to correctly replace my SSD?

auanasgheps · 8. August 2023

Hi there,

I want to replace the NVMe SSD in my NAS with a bigger one. I only have one NVMe slot in my motherboard.

This NVMe is NOT running the OMV system, but:

- has docker installed

- hosts the swap file of the system

- has a couple of shared folders

My idea is to image the drive with a live distro, install the new drive, copy the image to the new drive, and lastly extend the partition.

Would the new drive show up with the correct UUID and references or the OS would go crazy?

If not, are there any other methods?

The problem you may have is extending the partition. At this moment I couldn't say the reason but that usually gives errors, search the forum for threads about it.

If memory serves me right, one way to solve this is to create a fresh install of OMV on the new drive and then restore to that drive with fsarchiver, you should find a thread on that procedure as well.

Another method is to use omv-regen, it allows you to regenerate on a different drive, but read the conditions before you can use it. https://github.com/xhente/omv-regen

Hey, the new drive does not run OMV.

I am not replacing the system drive! OMV is happily running on a thumbdrive.

This NVMe drive is my apps/docker disk, but is heavily referenced in OMV. That's why I need to preserve UUID/paths

Oops, you're right. I read too fast, sorry.

So I don't know how to help you, I was surprised that you asked this question, now I understand.

Umm In that case I would try the method you exposed in your first post. Extending the partition with gparted may not be a problem in this case. You're right, it seems the best way, just make sure of that.

Seems that UUIDs are not tied to hardware, but to partitions. So I should be fine by cloning the partition. I'll eventually post an update here.

If you clone it, UUID will be the same so OMV won't know the difference.

I recall you changed the swap partition to a SWAP file.

Again, since the UUID of the new drive is exactly the same, there should be no issue with it.

You can stop using SWAP during the transition, just in case.

Only thing you'll have to do is resize the partition after you have the system up.

Nonetheless, you will always have your old drive to revert back, in case something goes sideways.

In any case, there are ways to modify the UUIDs. Search on google, you will find something quickly. I've read on the forum about it more than once.

Thanks for confirming Soma !

Since I have only one slot, I'll do everything "offline" using a live distro: by copying the image on a HDD and then restoring it to the destination NVMe.

The patient must be sleeping during the procedure so I don't mess anything up

My hope is I do not have to change ANYTHING after the restore!

Just a reminder: don't ever boot OMV with both drives connected.

This will give trouble to OMV since it's seeing 2x drives with the same exact UUID.

Only time the drives are plugged in, is when running the live clonezilla.

You can use clonezilla to make a copy of the drive and then on recovery you can automatically adjust the new drive size.

So yes, the process actually works directly.

If you do have OMV6 you can even select bootable CloneZilla entries to your boot menu, so no reason to boot from a removable device.

Why not simply buy an USB <--> NVME Adapter ?

(You'll gonna need one anyway, sooner or later)

And you could convert an "unused" NVME-SSD into a real fast USB-Stick.

SerErris · 8. August 2023

Yep, that would allow you with SystemRescue to dd from one device to another one. Or directly use Clonezilla

Little overkill and doesn't look like a USB-Stick.

I thought about something more compact, similar to this:

Was not serious about it and never was aware it exists. I just ordered one of the above (your link).
