Problem switching to a new HD

[DST73]

Hi,

I have cloned my internal SSD (sdb) to an new external device (sdc).
(The new SSD is a Samsung 970 EVO Plus NVMe M.2 SSD, inside a Dsonix M.2 NVMe SATA SSD USB Adapter)
Than I have changed the boot order in bios to boot from the new device

If I now look at the devices I see


but in the console it looks like

root@pve:~# lsblk

Does this mean that proxmox still uses the old device? How can I change this?

Initially I wanted to exchange the drive inside my mini pc but that is not possible because the screws to open the PC and to get access to the old SSD don't work anymore.
So I have to leave the old SSD inside

Thank you!

How exactly have you cloned your drive ?

 

[DST73]

I have flashed clonezilla on a usb stick and cloned disk to disk

 

[hd--]

clonezilla does not really copy byte to byte, but instead copies the content of the partition. And it seems to me, that it was not able to copy your logical volumes.
If you want to copy byte to byte use dd instead. Afterwards use parted or gparted to resize your partition [1] to use the full 1TB and also adjust the fs.

Yes, still using the old disk.

sda is a third disk that isn't in use or used by disk passthrough?

As others said it does not look like the copy was successful. Keep in mind even if you do copy the context, you will likely have to deal with duplicate LVM groups which may require manual intervention.

Additionally, since your old disk moved to sdB, and it was likely sdA before, and your OS booted - that means /etc/fstab is pointing at UUID of the disk (as it should). The OS will continue to mount old disk as root until you change things. But first, make sure you have a good copy. I would put more effort into eventually trying to either get rid of old disk, or at least disable it until you get a good boot going. Perhaps in the bios.

sda is an old disk that I used for backups (witch became to slow and was the reason I have bought a new one).
My old boot disk was sdb and after I have installed some time ago the disk for backups (witch was sda) it still was sdb
I think I will setup Proxmox fresh and install it directly on my new drive.

I have looked at some tutorials. If I understand it right I have to do the following steps.
1) Backup VMs and CTs to another drive
2) Install Proxmox on my new drive
3) Restore each backup of my VMs and CTs

Ok, its the Samsung 870 vs 970 that confused me at least.
So if the new disk is sdC - seems like copy has worked. At a high level you still need:
a) deal with duplicate volume groups, possibly by booting into live CD and de-activating sdB, activating sdC
b) deal with /etc/fstab
c) deal with boot loader : https://pve.proxmox.com/wiki/Host_Bootloader

good luck

Don't forget to backup your hosts "/etc" folder, especially "/etc/pve".

 

[DST73]

So I have installed Proxmox fresh on my new SSD.
I still have the same problem that if I backup a bigger container like the one of my docker looks like the whole system freezes.



But the backup is in progress

I have tried it with all three more or less new SSDs. Same problem. Backup freezes the system

And after some while the system is not reachable anymore




Looks like the new SSD in that USB device gets very hot



Any ideas what the problem could be?
Any way to give them backup-process less power?

If I connect a monitor to my mini pc I can see these errors



Thank you!

I have bought another SSD and and an ICY Box with an active cooling system.
No problems since than besides one that S.M.A.R.T does not work with that ICY Box

okay, so your backup problems are resolved then ?
As for your ICY Box I think you forgot to pass the --device[1] as suggested by the command, if this was also a question ?

[DST73]

Yes the backup problem seems to be fixed...

It is an IB-1816M-C31 but i can't find it in the list of supported devices

 

[hd--]

If you want to trust this article you can try using smartctl -d sntjmicron as your icy box is apparently using a jmicron bridge

 

[DST73]

Unfortunately that didn't work

Maybe some other switch might help, but there is also the possibility that your icy box is not (yet) supported.
