Is there any other tip or advice what to do with this issue?
Please try to help me.
(After update to 3.10.3 pakon stopped to work.
I have tried to tips already available in forum such as py script to create database,reinstall and restarts,but nothing helped.)
I did not deleted any file. And this did not help:
/usr/libexec/pakon-light/create_db.py
@xjerab08 Iām not sure if reinstalling pakon or running create_db.py will truly recreate the database if there are already existing database files. Since you were ok wiping out any existing pakon data anyway, try this:
Stop the pakon processes:
/etc/init.d/pakon-handler stop
/etc/init.d/pakon-monitor stop
Remove all extant pakon DB files, then recreate the DB (assuming you have the database files at the default places. /var/lib/pakon.db is the active db file in RAM, while /srv/pakon contains the DB backed up in persistent storage (one compressed DB file with the last 24 hours of data, updated once every 8 hours called pakon.db.xz, and another archive DB with all data older than 24 hours, called pakon-archive.db)
rm /var/lib/pakon.db
rm /srv/pakon/*
/usr/libexec/pakon-light/create_db.py
Then restart pakon:
/etc/init.d/pakon-monitor start
/etc/init.d/pakon-handler start
From my experiments pakon should be starting out with a completely clean slate this way.
As with the previous version Iām (not alone) experiencing issue Mountd spamming the system log about missing sda serial.

Please advise.
Was it necessary to post 3 posts about this issue? This doesnāt make anything better. The forum should be organized.
We know about your thread, but I couldnāt reproduce it, yet.
In recent days we received from other users that it is happening to them, too. Sometimes things require time to track them down and fix them.
Maybe a little notice from you in the thread would make us all a little more comfortable knowing Turris Team cares and would prevent me from desperate measures. 
Actually it had me post these 3 messages to know what I know now from your reply.
Thank you.
This actually helped! Thank you.
