Re: My root "/" FS is full
Has your system been down in single user mode lately? If that was the case, it may be possible that you stuck something under /opt and you do not see it...
If you remove something like a large /etc/rc.log or other open file, the space will not free until after a reboot.
Good luck.

Re: My root "/" FS is full
Look in /dev/rmt, someone may have written to a file om instead of 0m.
Also try:
find / -xdev -mtime 0 -size +100000c -type f | xargs ls -ld
if you can run it of course, and see what's been modified today, and is greater than 100k bytes.

Re: My root "/" FS is full
Try these commands:
# find / -xdev -type f -mtime -1 -exec ll {} \; > /tmp/newfiles
This will list you the newly created files ( 1 day ) in the system. As you have all other FS mounted under /, the search will list you all new files and may take some time to finish.
# find / -xdev -size +10000 -exec ll {} \; > /tmp/bigfiles
will give you a list of all big files ( >10000) under root.
Check the syslog file for any error messages.
HTH,
Shiju

Re: My root "/" FS is full
There you should find some big files. remove that.
then go to /etc /sbin /dev /bin directories and give du -sk *. It will give you the filesize in MB. Look for any big file which is not required and delete it.
Try to run cleanup -F

Re: My root "/" FS is full
you do a dd if=disk of=tape
but not the right device file, thus a file is created the size of disk...! until / fills/.
Check /dev/ using ll
Later,
Bill

Re: My root "/" FS is full
The root filesystem should grow hardly at all after system setup.
You should also look for large core files.

Re: My root "/" FS is full
first of all you should try to find the files/directories which cause the full filesystem:
cd /path/to_directories_where_you_changed_thing
find . -size 1000 -exec ll {} \;
perhaps you can cleanup your root filesystem by deleting unnecessary things...
Allways stay on the bright side of life!

Re: My root "/" FS is full
Simplest thing is to do du-k and will give you disk usage by files there you can figure it out which directory/file is occupying more space.
LAter delete those identified files.
Thanks,

Re: My root "/" FS is full
Probably someone was trying to take a backup and misspelled the device file name. Look for any files in /dev directory.
if your deivce is /dev/rmt/0m and you misspell it as /dev/rmt0m it will create a file rmt0m in /dev directory and woll start backing up to this file.
Hope this helps.
