Cara recover LVM

The command:

"vgcfgrestore -l VolGroup00"

shows a list of backed up configurations.

I found that the correct configuration was in the file "/etc/lvm/archive/VolGroup00_00054.vg".

Running "vgcfgrestore -f /etc/lvm/archive/VolGroup00_00054.vg" did the trick.

Cara reset local security policy di windows

Jendela XP:

Jendela Fista & 7 (maybe :D ):run secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
