root file system is full

[Norman_21]

Hello experts,

Please adivse the best method to check and purge the root file system. It is %100 full and I'm not sure what to do!
/dev/vg00/lvol3 86016 86016 0 100% /

This happend after I issued the command
find / *.gz -cpio /dev/rmt/c4t0d0BEST
it seems the output was not directed to the tape. instead it went somewhere within the root file systems.
points will be assinged.

Hi,

Check the size of the file /dev/rmt/c4t0d0BEST if its not a device file then remove it.

and to check if /dev/rmt/c4t0d0BEST is a valid device file before deleting it do
lssf /dev/rmt/c4t0d0BEST
it should not give u ??? after address.

Also check for any files bigger in size in /dev or / where it has dumped the output.

Shukla,

You know what, I just figured out that I used a stranger device name which is not existed in my hp-ux box.
It seems that I need some sleep.

Thanks.

Never mind it happens, but take extra precaution when its a production machine. And ya as systems need regular reboot and maintenance so do men. You need rest..

Shukla,

Is the command correct and will only backup the *.gz.
how to restore it and list the contents of the backup tape created by cpio.

Thanks.

[Rajeev Shukla]

Yes the command you have given is right.
And to view the contents of cpio tape use
cpio -ivB < /dev/rmt/
and to extract the cpio tape use
cpio -iuvB < /dev/rmt/

Cheers

Thanks Rajeev,

The command was directing everthing to the tape. However, I've corrected the issue:
find / -name "*.gz" -cpio

Thanks for the other info.
