After your suggestions I've dumped (using dd) some first sectors of /dev/dm-6 to check what is in header and I noticed LUKS label. I totally forgot that whole partition was encrypted (it used to be unlocked by external keyfile). So I unlocked partition first and after that activated LVM. All volumes are here, healthy and intact. About "lvroot" volume - it was never in use. I planned to install other distribution here, but I never did. Root filesystem is on non-lvm partition. Again sorry for this stupid mistake and thank you for your help. -- Regards, Grzegorz R. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
