Each time I shutdown/reboot I get these red colored messages:
----
Failed unmounting Runtime Directory.
...
Failed unmounting /var.
----
This has been happening since I installed Leap 42.1 (currently I use 42.3).
Nothing seems to have been broken so far but once during a recent boot there
was some more extensive disk check.

I have followed the steps given here:

As the guys in the forums asked to look at the beginning of the log here are
the first 20 lines of the latest log file:

These are the last 40 lines of the log:

The message "Failed to unmount /var" appears during shutdown right before this
message (I don't know why it is not in the log though):

[   31.245825] systemd-shutdown[1]: Unmounting /var.

/var is sdb3

Another message which always appears in the log is this one:

[   10.165896] FAT-fs (sdd1): Volume was not properly unmounted. Some data may
be corrupt. Please run fsck.

sdd1 is /boot/efi

Looking at SMART tests - all disks are fine, i.e. it is not a hardware issue.

I am hesitant to share the full shutdown-log.txt as I am cautious about the
security of the system (it seems to expose certain data) but if there is any
other way to diagnose this and provide necessary data please let me know.
