Could you please provide more information like the OS version, Olares version, etc.

Could you please try to execute the command

journalctl -u k3s > k3s.log

and provide us the file k3s.log

hi @nikoxp , based on the logs you provided, it's obvious that the Kubernetes system is suffering from a very slow I/O, to the extent that it can not even operate normally on its own, not to say install Olares upon it (the installation of Olares has not started yet).

what disk are you using? and what's its I/O performance? For the normal operation of Kubernetes, we recommend you use a SSD, or refer to the hardware requirements of ETCD (it's the backing database for Kubernetes)

[nikoxp]

my hardware:
128G SSD，4CPU，16Gmem，use Virtual Machine ESXI

There could be various reasons, e.g., maybe the virtualization layer is causing an I/O delay, or other processes are putting pressure on the disk, or a hardware issue.

But for what it's worth, you can do a simple test of the I/O performance on both guest and host OS, like: fio --rw=write --ioengine=sync --fdatasync=1 --directory=. --size=40m --bs=4096 --name=test

On Debian-based systems, you can install it by sudo apt-get install -y fio

The IOPS, bandwidth and fdatasync latency stats will be reported when the test ends.
