Issue!! Proxmox crashing randomly!

MrPete said:
SOLVED.... what a relief!
I had already run memtest, and the RAM had passed.
Yet... memtest86 has been radically strengthened since I last made my bootable copy.
Using the latest version? Bad RAM. Pull that RAM (still have 8GB, enough for now) and all is wonderfully well.

H/T @kalasnikov for the "long shot" thought, and @oguz for the reminder. I highly recommend getting a current version of the USB-bootable memtest86 dot com version.

And, I got to learn and document some important aspects of managing my Proxmox cluster :cool:

oops. it indeed seems like the OP disappeared :)

in any case i'm glad your problem is solved :)

if @pawanosman could report back we can set the thread to [SOLVED]
 
BLEAH. NOT fully solved:
  • With kdump-tools installed, apt update (and autoremove and more) fails 100% of the time
  • apt remove kdump-tools / apt purge kdump-tools fails to fully uninstall kdump-tools
I have edited my kdump-tools info above. I don't consider this fully resolved. My system now appears to work and update, yet:
  • find /etc -name kdump\* shows a dozen related files still there, and active during boot, shutdown, and apt actions
  • find /var -name kdump\* shows the service still there, and images present in /var/lib/kdump
I don't know how much of that is removable.

you need the kernel headers for that version installed, then update/upgrade via apt should work.

otherwise you can do alternatively:
Code: 
rm  /etc/kernel/postinst.d/kdump-tools
apt autoremove --purge kdump-tools kdump
apt update && apt dist-upgrade

please post the errors here if the above doesn't work for you
 
Sorry, I do not know what "kernel headers" are, nor for what version of what I need them ;)

I'd love to do this the "right" way before attempting the alternative...

kernel packages have their corresponding header packages pve-headers-<version> which can be installed with apt.

you can check your kernel version with uname -r, and install the header package: apt install pve-headers-$(uname -r) should do it
 
Ahhh... I already did the much-delayed update/upgrade after manually disabling enough of kdump-tools. I've installed the headers for the future (obviously would need to be redone as well... I'll add this to my little kdump-tools summary in anticipation that it will help someone in the future. :)
