[Mageia-dev] df lying?

Mon Jan 7 07:40:45 CET 2013

What is upstream for df command? In openSUSE 12.2, Cauldron & F18 on the same 64 bit system, df on the only partition on my 1TB data HD is obviously lying as to usage and free on a nearly full EXT2 
+partition:
+
+# df    # before copy

+/dev/sdb1      968990412 942397904  26592508  98% /disks/esata

+
+Unless this is a bug in df, how is this lack of info possible given the following filesystem info (e.g., no reserved blocks, and no journal) about the partition?
