Thank you very much Alasdair :-)
With reference to your messege:
https://www.redhat.com/archives/linux-lvm/2005-October/msg00007.html
"... some LVM2 snapshot operations are incomplete or hang and need prodding
or finishing with dmsetup (eg with a dmsetup resume or remove).
This is because the order LVM2 does some operations needs to be changed."
when and how exactly (in detail) should i use dmsetup suspend/resume
under lvcreate/
lvremove snapshot of lvm2 lgocal volume (especially XFS lv)?
Regards Hubert.
