Hi list,
as mentioned in my earlier post, LVM complains about
"Incorrect metadata area header checksum". As this occurs
often (many questions, rarely answers in the list) I tried to create
some 'new' via
# pvcreate --force --uuid 7vFXd3-MYnt-TVdG-luYr-rDPn-o8a1-vjewWk
--restorefile /etc/lvm/archive/alice_00038.vg alice
Incorrect metadata area header checksum
uuid 7vFXd3-MYnt-TVdG-luYr-rDPn-o8a1-vjewWk already in use on
"/dev/loop53"
--> also '-ff' doesn't do the trick
# pvscan -vvv
Processing: pvscan -vvv
