Disk Utilization
Hi,

Can anybody explain why my newly created 120G FS shows 100% utilization when only 113G of disk space has been used? ......


Code:
# df -h .
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg01-lvol0
                      119G  113G     0 100% /u02
#du -h /u02
16K     /u02/lost+found
112G    /u02/bckups/rmanfull
112G    /u02/bckups
112G    /u02

R,
D.

Reserved blocks?

Code:
tune2fs -l /dev/mapper/vg01-lvol0 | grep "Reserved block"

Hi,

Code:
# tune2fs -l /dev/mapper/vg01-lvol0 | grep "Reserved block"
Reserved block count:     1952816
Reserved blocks uid:      0 (user root)
Reserved blocks gid:      0 (group root)

Cheers!

You can modify the reserved blocks, but they are often used by root to fix problems like this. I tend to reduce the 5% overhead when I am dealing with disks of over 100GB. 5GB is a large amount to allow for cleanup. When dealing with 1TB LUNs it is even more important to not bother with 5% waste, as those resources can be expensive.

look for the -m option in tune2fs
