How to increase disk space

A

arupsarkar

Hi,

I have run out of disk space, as a result of which I cannot install anything, since I am new to unix can someone please suggest what I should do so that I can allocate some space to install. I do have space in my hard disk. I have attached the output of disk commands.

When I am trying to install win32 wireless driver using ndisgen I am getting the error.
Code: 
/tmp: write failed, filesystem is full
ndiscvt: failed to output binary image: No space left on device
CONVERSION FAILED

#
df -hk


Output
Code:

#
du -d1 -h -x /

Output
Code:

Any help is highly appreciated.

Your /tmp is rather small, only +/- 512MB. Mine's about 6GB. But as Matty said, see what's eating up the space.
 
Hi

The following is the output of /tmp

SirDice, How can I increase the space of /tmp?

# ls -ltr

Output
Code:

Try # du -sk /tmp/* | sort -n.

You can't increase it's size. You either partition it correctly to start with or mount a different filesystem on there.
 
Or if you have plenty of RAM to spare, turn /tmp into a memory file system with these rc.conf directives:

Code: 
tmpmfs="YES"
tmpsize="1024m"

Edit tmpsize as you see fit...
 
Or, as a slight variation on the previous point, use tmpfs (as opposed to tmpmfs) by adding the following line to your /boot/loader.conf:

Code: 
tmpfs_load="YES"

and the following line to /etc/fstab:

Code: 
tmpfs           /tmp            tmpfs   rw,mode=01777   0       0

Your /tmp filesystem will then reside within virtual memory, both RAM and swap, like Solaris does it.

(It's an experimental feature in FreeBSD, but I've been using it for a year with no problems)

Indeed it is. Careful though. Lots of linux people tend to stuff huge amounts of data into /tmp and you don't want to run out of memory x(

Having said that, my next machine will definitely use it. It will have 8GB ram so a 16GB swap would be in order. Since it's a bit of a waste I'd use tmpfs.

I currently have about 6GB space on /tmp. Mainly because I regularly extract dvd images and these gui tools tend to extract it to /tmp to make it browsable.
 
As far as I know, tmpmfs is based on mdmfs(8), which is swap-based. This is corroborated by /etc/defaults/rc.conf:

Code: 
tmpmfs_flags="-S"	# Extra [B]mdmfs[/B] options for the mfs /tmp

Therefore I believe that this creates a swap-based /tmp memory file system as well:

Code: 
tmpmfs="YES"
tmpsize="1024m"
tmpmfs_flags="-m 0 -o async,noatime -S -p 1777"
 
Hi All,
I would like to thank everyone for their contribution.

The issue has been resolved. I had implemented what "jem" had suggested and it is working fine so far. Thanks "jem".
