[linux-lvm] vgchange -ay --partial fails



hi!

i still have a broken volume and i still have the wish to get at least some data back before dropping the whole configuration.

the very promising way "partial" failed, i could not mount the broken volume.

what else can be done?
can I fake the missing device (i.e. write the uuid)?

thx, chris

the comlete shell output:

       ide-scsi so that sr0 or sda or so is needed?)
