Here is the situation
i have a 750gb disk with luks partition. inside is a lvm pv and volume group.
opening it by hand with cryptsetup and doing vgchange -ay works just fine. however, somewhere after 20 minutes the device nodes for lvm volumes are no longer there, and any lvm commands seem to stall and not produce any output.
currently mounted lvm volumes work fine.
is anyone else experiencing this?
