Hello

after a lvm snapshot creation and a reboot are all logical volumes are  
missing, only swap is present.


     lvcreate -L 5000M -s -n centos_h1-root_snap /dev/mapper/centos_h1-root

     lvs
       LV                  VG        Attr       LSize    Pool Origin  
Data%  Meta%  Move Log Cpy%Sync Convert
       centos_h1-root_snap centos_h1 swi-a-s---    4,88g      root   0,00
       home                centos_h1 -wi-ao----   15,00g
       root                centos_h1 owi-aos---   20,00g
       swap                centos_h1 -wi-ao----    7,62g
       var                 centos_h1 -wi-ao---- 1000,00g


     after reboot no complete start, dracut console is running:

    dracut:#
     ls /dev/centos_h1/
     swap

     dmsetup info shows swap only, too

I can reproduce this on 2 different Servers and a Virtual Machine have  
same behavior.

What do i wrong?



Greetings
