udisks2 (udisksd) errors in syslog: how to investigate?

Asked by mm

Hi,

my system logs of my Ubuntu 18.04 Intel NUC are getting spammed by these error messages:
udisksd[1369]: udisks_mount_get_mount_path: assertion 'mount->type == UDISKS_MOUNT_TYPE_FILESYSTEM' failed

I figured out that the spamming is due to Docker which is installed and got some containers running. But with Docker and all containers stopped the error also occurs in the syslog but not that often.
Googling this error message didn't get my any help.

Does someone have any clue how to investigate this issue?

added:
It is not hardware related since I changed the NUC and I have a similar configured NUC running which doesn't have this errors.

Solved it:
in my case it was in fact Docker related. I stated in my question that I stopped Docker and the problem persisted. This is still true. The problem was due to booting with Docker auto start enabled while it tried to start a container which had a volume on a LUKS device that wasn't present at boot. After stopping Docker the udisksd log spam persisted. I solved it by disabling auto start for the container which has its volume on a disk that is not present at boot time. After that no more errors appeared and I was able to manually start the container.
