today the mounts are missing ... the old bug is back ...

So we are back at square one. What we are facing here is apparent lvmetad deadlock. There are two upstream patches that fix possible deadlock case there. I added them to my package and updated it. You could test it. What would be really helpful - before updating try to trigger the problem and provide lvmetad backtrace. This would show where it is stuck. Find out lvmetad PID (e.g. using "pgrep -l lvmetad") and then use gdb to obtain backtrace with "thread apply all backtrace", like bor@opensuse:~> pgrep -l lvmetad 557 lvmetad bor@opensuse:~> sudo gdb -p 557 root's password: GNU gdb (GDB; openSUSE 13.1) 7.6.50.20130731-cvs Copyright (C) 2013 Free Software Foundation, Inc. ..
