Inline upgrade of Debian Buster

[nevj (Neville Jackson)]

@Rosika

Update: Success

… at least it seems that way.

Hi Rosika,
Congratulations.
That was not easy inside an NBD
You could use that extra 10Gb at the end to

• expand the home or swap partitions
• expand the root partition again at some later stage
• make a new partition.

I hope 22G for / is enough?

I wonder why QEMU used msdos partitioning inside the qcow2 file. That is why you have that extended partition arrangement.

Make a backup now of the new qcow2 file
before you try upgrade.

Regards
Neville

In 3 years, doing fortnightly upgrades, it has never missed a beat. Not even a warning message. Nothing. It just works.

My OrangePi 2E+ running Armbian 16 (Ubuntu 16 armhf) has been going for 5+ years (May 2018) and has 401 days of uptime - not that this is a widdling competition - it’s actually managed to power on through the odd power brownout too - no idea how - but it’s the only device on my network that can survive a brownout… I reckon 401 days ago would have been either me accidentally unplugging its power brick, or, when my suburb was cutover to underground power… It doesn’t do much, just transmission-daemon saving torrents to my NAS (which is very temperamental when it comes to brownouts, but it is an x86_64 “server” machine with an ATX power supply)…
Sorry @Rosika for butting into your thread

You dont do upgrades? That requires a boot and ruins your record.

It’s EOL Ubuntu 16 - so no updates - especially not kernel updates…

Hi all and thanks for your replies,

@nevj :

@nevj

Congratulations

Thanks a lot. I´m glad it worked out fine in the end.

@nevj

make a new partition.

You´re right. That´s always a good idea. The other options are also fine. Thank you, Neville.

@nevj

I hope 22G for / is enough?

I hope so. When I tried to upgrade to Bullseye it complained there wasn´t enough space left on /dev as 2 GB worth of data had to be downloaded.

@nevj

Make a backup now of the new qcow2 file

I took a snapshot of it with the virsh command. That should be good enough, right?

No problem, Dan.

Should be better than just backing up the file… it should also save the virt-manager settings I think
see this

KVM backups with Virt-Manager

So if you like to mess around like I do, you’re probably familiar with the idea of virtual machines. I like to use a program called virt-manager under Linux to create and work in VMs. It’s quick and easy, and gets the job done. But you’re probably wondering how you backup said VMs. I’m here to show you. First list the VMs you currently have available to make sure they’re shut down : virsh list --all Id Name State ------------------------------ 52 ActualArch running - ar…

Thanks, Neville, for the confirmation and for providing the link.
I´ll look into it.

Many greetings from Rosika
