While trying to resize a filesystem, I found that umount failed with busy while fuser and lsof didnt display any files open, found a post the suggest the following
- fuser -vm /var
To create a ext4 fs with more Inodes (df -i) about double the standard.
- mkfs -t ext4 -i 8192 /dev/sda6
List by uuid
- ls -l /dev/disk/by-uuid/
