Hi list,
Ive moved the _tmeta part of a thinpool to a (ramdisk) device for
testing and wanted now to move it back to disk, but this fail:
# pvmove -v -n /dev/mapper/dmivg-winthinpool_tmeta /dev/ram0 /dev/sdg1
WARNING: Failed to connect to lvmetad. Falling back to device scanning.

It seems, that pvmove is trying to create a mirror-device from *_tmeta
on the target disk, but this seems to fail.
The computer is still running, so do I have a possibility to save the
situation? Can I transfer the *tmeta in another way?
LVM und Thin-provisioning-tools are from git today.
Tfh!
Oliver
