Paritions to install Ubuntu

[Dimitri Mallis]

ok well i figured out eventually how to make snapshots...

i resized music to 50G then ran this command

dimitri at OuZo:~$ sudo lvcreate -L10G -s -n rootBackup /dev/ursus250/lvRoot
  Incorrect metadata area header checksum
  Logical volume "rootBackup" created

but i want to know if there is a way to *not* specify the size of the
backup, so i will make a back up that is the right size with out using 10G
(im only using about 1.3G of my / partition anyway, but this will soon
change.)

then how would i restore form this snapshot?

also how can i fix this error? > Incorrect metadata area header checksum <

thanks
