ESP folder on one Proxmox node quite full

[G0ldmember]

Hi,

I'm encountering errors on one node in the Proxmox cluster because everytime there is a kernel update, it fails, because the ESP partition is full. I have to manually mount it, delete one old kernel to make the update work.

I was analyzing why this only persists on one of the nodes and discovered that on the ESP partition in the EFI/proxmox folder, there is:

/EFI/proxmox# ls -1
5.3.18-3-pve
5.4.101-1-pve
5.4.103-1-pve
5.4.106-1-pve

This looks like old kernel versions. Current kernel is 6.5.13-5-pve.
The other nodes also have these folders, but not that many. That's probably the reason why kernel updates always fail.

Now the question: can these folders be safely removed? There is none of the kernels installed on the system (not even in rc state).

Is that a place / directory maybe where in former Proxmox relases kernels were stored and this is not required anymore?

Can't you just uninstall them with apt purge pve-kernel-5.3.18-3-pve (and the other's as well)? apt autoremove removes most old kernels automatically (on recent Proxmox versions) for me.

No I can't uninstall them, because they are not installed .
Maybe they were installed in the past but as mentioned above, I cannot even find a "rc" entry with dpkg -l for those kernel versions.
Also apt autoremove does not remove those directories.

# apt purge pve-kernel-5.3.18-3-pve
