>Description:
using FreeBSD 5.3 amd64 as nfs client
FreeBSD 4.10 i386 as nfs server
when a disk is filled up over 100%, Avail becomes negative on the
server, but hugely postive on the 64-bit platform. Not very
surprising, but still a bug... :)
4.10 i386 server:
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/da6s1f 17388202 16153532 -156386 101% /dumps/0
5.3 amd64 client:
Filesystem 1K-blocks Used Avail Capacity Mounted on
banan:/dumps/0 17388202 16153532 18014398509325598 0% /mnt
>How-To-Repeat:
1. fill up a volume on FreeBSD 4.10 i386 to 101%
2. nfs mount this system on a FreeBSD 5.3 amd64 system
3. df on the 5.3 amd64 system reveals LOTS of space on the volume. :)
