unable to open file '/etc/pve/nodes/xxx/qemu-server/202.conf.tmp.4147698' - Input/output error

Hi team,
I am having a dilemma with my data virtual server, this fine morning i saw it had a warning icon about i/o on my VM. I tried shutting down the virtual machine using the qm stop command to reboot, and unfortunately it failed to restart and gave me an error warning: unable to open file '/etc/pve/nodes/xxx /qemu-server/202.conf.tmp.4147698' - Input/output error
I tried using qm start 202 but it didn't work, I checked my 202.conf file is still on the system, how can I solve this problem.

Check if your root disk is full, check it with:

* df -h
* lsblk

Could be a full disk or a broken disk.
