I've this Linux machine:
Linux version 2.6.18-371.3.1.el5xen (gcc version 4.1.2 20080704 (Red Hat 4.1.2-54))
I run df command:
[ora11g@hy]$ df -h
Filesystem Size Used Avail Use% Mounted on
9.7G 6.8G 2.5G 74% /u01
59G 47G 8.2G 86% /sxr/oracle
I'd like to know Why the total size 9.7G isn't the same as Used+Available 6.8G + 2.5G (9.3G) and total 59G isn't the same as 47G + 8.2G (55.2)?
Thanks in advance!
