[SunHELP] disk space

[Fletcher, Joe]

It's also useful to account for a process which has space allocated but =
not
actually used.
A quick look at the filesystem with lsof might be enlightening.

No Gurus here, only us users...

But anyway, du gives you the disk usage, i.e. the space that the files =
on
the filesystem currently require. I assume that you calculate the =
amount
of "supposed" free space by comparing the output of du to the total FS =
size.

Be aware however, that Solaris - like any other UNIX - by default =
reserves
a given percentage of disk space for superuser use only. Using df -k =
will
give you the free space in kilobytes _without_ the space reserved for =
the
root user. Thus adding up the used and avail fields will yield a total =
of
less than the total kbytes field. Capacity will show 100% while the =
minfree
of, say, 5% may still be free but not available to a "normal" user.

If the difference actually proves to be 1GB, your FS must be HUGE (or =
your
system default minfree parameter screwed...) ;-)

Hope that helps,

Jerry
