[PVE-User] Proxmox upgrade 4 - 5

[John Crisp]

I have been critical of some things in the past with Proxmox, so to be
even handed I thought I'd just drop a note to say over the weekend I did
2 in place upgrades from v4 -> v5

Both went pretty well as smooth as silk, the only issue being that on
one of them the old boot partition didn't have enough room for a new
kernel and the dist-upgrade failed when trying to regenerate initramfs.
(it was originally a V3 upgraded to v4) Slightly scary minutes.....

Perhaps a note on the wiki to say check for space before upgrading older
systems would be helpful (assuming you have an older system with this)

Beyond that, thank you for making the transition so easy.

...'im not involved in Proxmox, but... i think this is a 'debian' thing
and not a proxmox thing... and the wiki page (i suppose this:

https://pve.proxmox.com/wiki/Upgrade_from_4.x_to_5.0

) say explicitly to read the debian documentation:

https://pve.proxmox.com/wiki/Upgrade_from_4.x_to_5.0#External_links

where:

https://www.debian.org/releases/stretch/amd64/release-notes/ch-upgrading.en.html#sufficient-space


Sayed that... welcome to the «damned me! why i've crated a so small
/boot (or /) partition!» sysadmin (very large ;) group. ;-)

LOL - but actually it was created automatically by Prox when it was
originally installed so not really my fault ;-)

yes, makes sense to note this! Bit bad luck to run into this just on major
upgrade...

ensure your /boot partition, if any, has enough space for a new kernel (min 60MB) - e.g., by removing old unused kernels (see pveversion -v)

cheers,

It did lead to a few minutes of panic :-)

Fantastic - and thanks.
