udisksctl monitor shows it is mainly by microk8s. What happen?

FYI I have this on a ubuntu 20.04 system with kubernetes installed using kubespray.

I did use microk8s at one point, but had already stopped it.

Interestingly if I run nautilus on this machine, it freezes. Same with all browser file save dialogs.

Running

systemctl stop --user gvfs-udisks2-volume-monitor

Fixes both the 100% CPU issue, and makes nautilus stop from freezing

I’m getting this issue when deploying Kubeflow, which has lots of pods that require storage. Since I’m not running the cluster full-time, I was able to work around this by running systemctl stop --user gvfs-udisks2-volume-monitor to disable the gvfs-udisks2-volume-monitor process.

Also, I tried adding the x-gvfs-hide option to all of the mounts, which didn’t seem to help. udisksctl monitor showed very few events (unlike before adding the option), but gvfs-udisks2-volume-monitor still ate up CPU. It’s possible that’s due to me remounting with the flag instead of mounting with the flag. Here’s what I ran to add the flag:

mount | grep /var/snap/microk8s | cut -d" " -f3 | xargs -I{} bash -c "echo {}; sudo mount -o remount,x-gvfs-hide {}"
