Each filesystem has a reversed amount, it defaults to 8%.

Drive Space

[Steve Laurie]

Hi,

Just wondering if someone could explain what's going on with my drive  
space.


I've got 2 x 500GB and 1 x 1.5TB SATA drives.

/dev/ad5p1 on /data/backup (ufs, NFS exported, local, soft-updates)
/dev/ad6s1a on /data/windows (ufs, NFS exported, local)
/dev/ad7s1a on /data/Public (ufs, NFS exported, local)

What I can't understand is why when I do 'df -h' or 'df -k' the Used  
and Avail amounts don't add up to the Size:

# df -h
Filesystem SizeUsed   Avail Capacity  Mounted on
/dev/ad5p1 1.3T131G1.2T10%/data/backup
/dev/ad6s1a451G113G302G27%/data/windows
/dev/ad7s1a451G 31G384G 8%/data/Public

# df -k
Filesystem  1024-blocks  Used  Avail Capacity  Mounted on
/dev/ad5p1   1442083968 137575328 129008780410%/data/backup
/dev/ad6s1a   473012182 118932864  31623834427%/data/windows
/dev/ad7s1a   473012182  32967330  402203878 8%/data/Public



Can someone explain where I'm going wrong?

A minimal installation usually takes about 120MB.  Are you adding X,
or any additional packages?

This line should be:
if [ $i -gt 89 ] ; then

The spaces between the leading and trailing brackets are mandatory, and
you had 2 spaces between the ; and 'then', and the comparison operator
for integers is '-gt' for 'greater than'.  I don't believe you need the
ticks around 89 either.

   use  df(1) 

   generally you wantdf -k   to make it display in kilobytes 
   ordf -m   to make it display in megabytes
   You might also want to use -l if you only want local disk (not NFS)

Linprocfs shows up twice because you have mounted it twice, probably
by mistake.  If it does not appear twice in /etc/fstab, I don't know
how it happened, but you can have any number of them just by running
"mount /usr/compat/linux/proc" lots of times.  Most people only mount
it once, though :-)

Swap space is not shown by "mount".  You can view your swap partitions
with "swapinfo" or "pstat -s".

That is the 8% reserved for root use (actually the space is reserved
so FFS can do a decent housekeeping job, but root can use it in an
emergency).

Missing hard-drive space?

[Adam Bender]

I installed FreeBSD recently, and noticed something strange when I run df:
(15:28:00) proteus:~/$ uname -a

I have BSD installed on /dev/ad1s3a.  The minor questions I have are why
does linprocfs show up twice, and why does my swap not show up?  But the
big question is where did the missing HD space on ad1s3a go?
14332M total - (2930 usedM + 10254M avail) = 1148M unaccounted for.  My
swap (on /dev/ad1s2) is only 94M.  Anyone have any ideas?
