LVM is terribly flawed and most imprudent piece of any filesystem that you can have for snapshot'ing!
The only snapshot-friendly filesystem or volume manager is ZFS. Whether create a single snapshot or few hundred thousand. It is instant and no data is lost.

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, tooI can reproduce this on 2 different Servers and a Virtual Machine have same behavior.
What do i wrong?
