/dev/dm-19: read failed [solved]

Hello.

When I do a pvscan I get
/dev/dm-19: read failed after 0 of 4096 at 73018572800: Eingabe-/Ausgabefehler
/dev/dm-19: read failed after 0 of 4096 at 73018630144: Eingabe-/Ausgabefehler

/dev/dm-19: read failed after 0 of 4096 at 0: Eingabe-/Ausgabefehler

I checked it with dmsetup ls
vmdisks-vzsnap--node1--0 (253, 15)
vmdisks-vm--103--disk--3 (253, 9)
vmdisks-vm--104--disk--1 (253, 6)
vmdisks-vm--103--disk--2 (253, 8)
vmdisks-vm--103--disk--1 (253, 7)
vmdisks-vzsnap--node1--0-cow (253, 14)
vmdisks-vm--101--disk--3 (253, 5)
pve-swap (253, 0)
pve-root (253, 1)
vmdisks-vm--101--disk--2 (253, 4)
pve-data (253, 2)
vmdisks-vzsnap--node1--1-cow (253, 18)
vmdisks-vm--109--disk--1-real (253, 12)
vmdisks-vm--101--disk--1 (253, 3)
vmdisks-vm--109--disk--2 (253, 17)
vmdisks-vm--109--disk--2-real (253, 16)
vmdisks-vm--109--disk--1 (253, 13)
vmdisks-vm--108--disk--2 (253, 11)
vmdisks-vm--108--disk--1 (253, 10)
vmdisks-vzsnap--node1--1 (253, 19)

lvscan is telling
ACTIVE Snapshot '/dev/vmdisks/vzsnap-node1-0' [2,00 GB] inherit
inactive Snapshot '/dev/vmdisks/vzsnap-node1-1' [2,00 GB] inherit

Backup leaved the vzsnap back.
How can I savely get rid of the vmdisks-vzsnap?

lvremove and dmsetup remove dis the job.
