Can you elaborate more on your RAID/lvm setup? As you have found, cp -a and rsync are very slow when copying lots of small files and hard links. The fastest way to copy the partition is to copy the raw partition using dd, then grow the partitions and then grow the filesystem. I'm not that familar with lvm, but assuming you have lvm over your RAID partition, you would do this: 1. Setup new drives w/RAID + lvm. 2. Copy old lvm partition to new lvm partition using dd. You will copy 80gb of data over. 3. Grow the filesystem. Whether you are using xfs or ext3 or <filesystem x> should not matter as long as it supports growing the filesystem. Of course, you'll have to have the data partition unmounted during all of this. -Dave ------------------------------------------------------------------------- Take Surveys. Earn Cash.
