Disk space

Hi all,
I have a SUN Solaris machine with the below specification regarding disk space...
bash-3.00# df -h
Filesystem size used avail capacity Mounted on
/dev/dsk/c1t0d0s0 6.5G 6.2G 170M 98% /
/devices 0K 0K 0K 0% /devices

swap 968M 1.4M 967M 1% /etc/svc/volatile

/dev/dsk/c1t0d0s7 60G 10G 50G 18% /export/home

As you can see i have a problem on the / partition and need to free some space from it...I would like to ask please about how I can list all files in that partition ordered by size in order to delete them

Regards

omarfarid

check under /var dir for logs that are too big

cd /var
du -k . | sort -rn

this could be done from / as well

yuzh

I would use:
du -sk * | sort -nr
under / and /var
to check it out, as omarfarid alread point out, it could be the logs are too big. also you need to check /var/mail to see if the mail boxes are growing too big as well.

Dear Sir,

I found out a file under /var/mail that is taking a lot of space as you can see below:

ls -lrt
total 21842
drwxrwxr-x 2 root mail 512 Dec 19 10:00 :saved
-rw-rw---- 1 root mail 11166522 May 15 07:05 root

Please let me know if i can remove and create this file again and how I can do that?

Regards

yuzh

if you don't want to keep the email for root, you can login as root (or su as root) and do:
cat /dev/null > /var/mail/root
to get rid of all the emails for root.
PS: the mail box is not that big
have a look at /var/crash/<yourhostname> to see if any crash file in there, you can delete them.
also have a look at my answer in http:Q_20378148.html to see if you can free up more space.
Have a nice weekend!

I did everything you asked me to do...I have only win some MB...I need to free more

omarfarid

you should be able to see other big files. Did you look under /var/adm for messages* files?

Dear Sir,

Please find attached a file that contains the size for all my file system

Regards
FIle-Size.txt

omarfarid

what do you have under /export/home/var ? it has 7.4 GB

7487651 /export/home/var

look for files that you can delete

Also look at xport/home/var/mya2billing , it has 2GB

2167449 /export/home/var/mya2billing
