The vgexport/vgimport can be done in only seconds whereas a tar/cpio/frestore might take hours depending upon the volume of data.<BR /><BR /><BR /> Mon, 28 Mar 2005 15:31:30 GMT A.

I've read some threads about coldinstall where they mention a filesystem backup as well as vgexport/vgimport non-vg00 filesystems ... Is it really necessary? Thanks in advance.
