DRBD extension not working on arm / rock64
Hi,
Apologies I don't really know how to debug this, but on my rock64 when using the DRBD extension I seem to be missing the drbd module :
talosctl --talosconfig talosconfig -n mynode list /lib/modules/6.1.58-talos/extras
NODE NAME
1 error occurred:
rpc error: code = Unknown desc = lstat /lib/modules/6.1.58-talos/extras: no such file or directory
The same config deployed on x86 machines does have that directory populated with the .ko files as expected. I tried using the tag and also the specific arm hash from here, to be sure but no luck when "upgrading" to the same version to rebuild the initramfs.
I can't access the display for that node, not sure which service log might explain why this is failing ? Thanks
There isn't enough information in the ticket. Is the drbd extension installed? Does it match Talos version?

Since the directory isn't present on the host I assume it's not, but I don't know how else to check. Linstor definitely isn't finding the DRBD module in any case, so it's not just a path issue.
It is the same (latest) version yes :
image: ghcr.io/siderolabs/drbd:9.2.4-v1.5.4
As stated the exact same config on two other x86 nodes does work fine, the issue is only on the rock64 which is arm64.
you can check yourself that the extension does contain the files, so the problem is somewhere probably on your end:

Alright, after a lot of digging I think I figured it out. The issue is the rock64 doesn't really have enough memory to schedule much, and certainly not the piraeus-operator. Even without that the upgrade command just silently kills the node unless I use --stage, I'm guessing because there's not enough memory to run the installer + the whole stack at the same time.
Using --stage I did manage to get drbd installed correctly, but that doesn't leave enough ram to schedule the piraeus-operator (it brings the node up to 107% usage).
Nevermind, I'll get rid of that node, thanks for your help
