Hello,
I am running gentoo-prefix on OSX which builds coreutils. When I
compare the output of the system df to the standard GNU df I get:
$ /bin/df -h /data/hirise06
Filesystem Size Used Avail Capacity Mounted on
hiserve2:/vol/hirise06 7.9Ti 430Gi 7.5Ti 6% /data/hirise06
$ df -h /data/hirise06
Filesystem Size Used Avail Use% Mounted on
hiserve2:/vol/hirise06
2.0T 431G -523G - /data/hirise06
The 2.0T size looks suspicious to me. Maybe an integer is overflowing somewhere?
I'll also note that this was reported some time ago to the macports
bug tracking software (https://trac.macports.org/ticket/16480) but
their resolution was requesting an upstream fix.
Thanks,
-Tim
