Hi,

i run a alpine linux 3.22 xen system on a usbstick with diskless mode.
Everything works fine but only the mountpoint of a filesystem who is on
a software raid + lvm volume failes to mount on the boot.=C2=A0

printout: dmesg

[   40.883538] /dev/mapper/dgrp1-vDOM: Can't lookup blockdev         =20
[   40.883799] /dev/mapper/dgrp1-data: Can't lookup blockdev      =20



after i log in on the console and do a mount -a everything works fine.

can some one give me a hint what could be missing ?

many thanks

cheers
Michael
