Hi Folks,
How do I properly backup and restore / on LVM2 , e.g.
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/rootvg-rootlv
2621356 1902288 719068 73% /
tmpfs 25165824 4 25165820 1% /dev/shm
/dev/cciss/c0d0p1 106040 45992 60048 44% /boot
Am running SLES9 , should be similar in Redhat and my pvdisplay looks
like, HW RAID 1.
