I recently upgraded a machine from Solaris 2.4 to Solaris 2.5.1, and ran into
a bit of weirdity. I copied the user's home directory (the only home directory
on the machine) from /export/home (which had its own partition) to an
NFS-mounted drive. When I installed 2.5.1, I did an Initial installation,
increased the size of the /export/home partition. When I copied the user's
home directory back, I didn't get any error messages, yet when I did a "df -k"
on the 2.5.1 partitioning, I find that /export/home is now 100% full. Is
Solaris 2.5.1 more inefficient than 2.4 in diskspace usage? Has anybody else
encountered such a phenomenon?
