Very odd. I created a PV on a new drive: # pvcreate /dev/sda1 Then I created a VG and used it: # vgcreate TestVG /dev/sda1 # vgchange -a y TestVG I created an LV on it, formatted it and mounted it: # lvcreate -n TestLV -l (number of extents) TestVG # mke2fs -j -L TestDisk /dev/TestVG/TestLV # mkdir /media/test # mount /dev/TestVG/TestLV /media/test Then I unmounted it and split it off to a new VG, activated the new VG and mounted the old filesystem: # umount /media/test # vgchange -a n TestVG # vgsplit TestVG TestVG1 /dev/sda1 # lvchange -ay TestVG1 # mount /dev/TestVG1/TestLV /media/test The trick here is that the original VG must be inactive before you do the split. AFAIK, the only way you can do that with your stuff now is to boot off the rescue CD, let it mount the stuff, then follow the steps I did starting with "vgchange -a n ..." ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@xxxxxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - Tempt not the dragons of fate, since thou art crunchy and taste - - good with ketchup. - ----------------------------------------------------------------------
