I would like to see the domain metadata - it is stored in the metadata lv or
in the vg tags.
Please attach the output of these commands:
dd if=/dev/2e94bbac-1648-49db-8605-ce574d2bc240/metadata bs=2048 count=1 > domain-metadata-lv
vgs --noheadings -o tags 2e94bbac-1648-49db-8605-ce574d2bc240 > domain-metadata-tags
Thanks,
Nir
