ext4 partition size / free space discrepancies
I am simply confused by some output I'm seeing. When I run "df -h" the lines that are confusing me are as follows:
Filesystem Size Used Avail Use%
/dev/mapper/sysvg-lvvideos 293G 4.5G 274G 2%
When I run "vgdisplay" I get:
--- Volume group ---
VG Name sysvg

Metadata Areas 2
Metadata Sequence No 8
VG Access read/write
VG Status resizable
MAX LV 0

Open LV 4

When I run "lvdisplay sysvg" I get:
--- Logical volume ---
LV Name /dev/sysvg/lvvideos
VG Name sysvg
LV UUID ZXNPP0-2IUI-UT1s-3riN-fxZH-QmfW-3OgwPI

LV Size 293.00 GiB

Read ahead sectors auto
- currently set to 256
Block device 254:2
What I don't get is: 293 - 4.5 does NOT equal 274. I have 14.5 GiB unaccounted for.
