zstd: error 70 : Write error : cannot write block : No space left on device

[Peter S]

Hi,

While trying to update the Proxmox server, the "/dev/nvme1n1p2" ran out of space.
Searched already for the same issue but could not find the right solution yet.
What to do?
1. Get rid of the "config-6.5.13-5-pve", "initrd.img-6.5.13-5-pve", "System.map-6.5.13-5-pve" and "vmlinuz-6.5.13-5-pve"? If yes, how, "sudo apt-get autoclean", "sudo apt-get --purge autoremove" and/or "sudo apt autoremove" will not remove the files?

2. Or increase the "/boot" partition? How?
3. Something else?????

Hope I've provided the right information below.
Thank you in advance!

I would remove 6.8.4-3-pve packages, and possibly consider moving /boot to a separate disk to avoid resizing hassle.

/boot // /boot/efi should be ~1GB these days, you could maybe move it to USB3 disk since it's only accessed on boot and when the kernel gets upgraded

Thank you!
Will move the partition /boot in the future to another disk.

For now, I'm a little bit afraid to remove files from the /boot...can I use "rm" or do I need to use another statement in this case?
rm config-6.5.13-5-pve
rm initrd.img-6.5.13-5-pve
rm System.map-6.5.13-5-pve
rm vmlinuz-6.5.13-5-pve

PS: Can I remove the files of *-6.8.4-3-pve as well because 6.8.8-1-pve is in use?

 

[Kingneutron]

dpkg -l |grep '6.8.4-3'

Those are the packages you'll need to remove; the initrd may/not be left over afterward and could be rm'ed manually. You should arguably leave the 6.5 kernel in place just in case, as 6.8 has a bunch of known/reported problems.

Hi Kingneutron,

Thanks again, I've used the following commands to remove the "old" kernel:
sudo dpkg -l |grep '6.8.4-3'
sudo apt-get --purge remove proxmox-kernel-6.8.4-3-pve-signed

And I was able to successfully upgrade the system :
sudo apt update -y && sudo apt upgrade -y && sudo apt full-upgrade -y && sudo apt autoremove -y
