Re: [linux-lvm] How to fix inconsistent LV structs?



Raffael,

nothing in the log directly related to LVM :(
But your hint WRT naming devices could help us.
Do you have devfs mounted on /dev and don't use the full devfs
names in all cases?
If so, please retry giving the full names.

Regards,
Heinz    -- The LVM Guy --
