Hi all, I just reordered my disk space: shrunk /dev/hda6, created a new partition /dev/hda10 with this new space and added /dev/hda10 to the existing volume group vg_uhu00. After that I could boot and all seems to be fine. but running vgscan I get root@uhu:/home/ecki/backup/uhu# vgscan Reading all physical volumes. This may take a while...

I can't check, because lvdisplay gives the same output as vgscan above. I have a line filter = [ "r|/dev/cdrom|", "r|/dev/hda[1,6,7]|" ] in my /etc/lvm/lvm.conf Any suggestions, how to get a clean volume group? Thanks a lot Ecki -- Eckhard Kosin Kaspar-Kerll-Str. 41 D-81245 München, Germany Tel.: (+49)(+89) 88 88 479 Tel., Fax: (+49)(+89) 835 844 mailto:Eckhard.Kosin@online.de _______________________________________________ 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/
