Research: What is the best way to remove LVM's left over device files.
Rsync backup; This is a dry run which will delete files not on the source, log everything to ~/backup.log, exclude a video directory from all files named /mnt/raid5 to /mnt/backup.
# rsync -avn --delete --log-file=/root/raid5_backup.log --exclude drew/video /mnt/raid5/ /mnt/backup
The real deal.
# rsync -av --delete --log-file=/root/raid5_backup.log --exclude drew/video /mnt/raid5/ /mnt/backup
