Clonezilla is probably the fastest way to copy non-raid disks (lvm works if it is on a single drive) because it knows enough about most filesystems to only copy the used blocks. It also lets you use a network share (nfs/smb/sshfs) for intermediate storage of compressed images so you don't have to connect the source and target drives to the same system or access them at the same time. The target disk has to be the same size or larger and you will have some extra work to do if the target hardware needs different disk drivers. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
