Login failure due to /dev/root file system full

[Purushothaman_1]

hi
When I am trying to login to HPUX 11i with any account box I get following message

Wait for login exit: ..

Does anybody has workaround this problem?

Thanks in advance

Hi,

You can try creating some free space through some allready logged in user.

Or you can try logging in at the system console which should be able to let you in where you can do the needful.

Hi,

Is there MP/GSP in your server? If yes log into that IP and try logging in using root.

Otherwise go to system console and try logging using root.

Are you not trying root login?

hi
I tried to login using console port. Console port was displaying errror that unable to write to log file due to 0% Free diskspace. I hard booted the system. Now I could able to login to the sytem with non root user and root user in failsafe mode.

These are my disk statstics
$ bdf

I would like to extend the volume space for the mount point / using sam but couldnt due to SAM unable to umount the file system as lots of process are running for this mount point. I found this using fuser-cu command.

Is there a way to increase this???

Hi,

It is not possible to increase root like this unless you have Online JFS installed. With that also it is quite tricky as your root has to be contiguous and there may not be free extents available after root LVOL in your vg.

A better idea will be to look for some big files lying in root, Otherwise rott should not gro in size. A commonly mistyped backup command sometime create huge files in /dev causing these symptoms.

You can check for utilization of the space under root by.

#du -t vxfs |sort -rnk 1 |pg

It will least biggest file on top and will help to find the file taking huge space under root.

Hi Purush,

This means auditing is enabled on your system. You can switch audit log file and can also null out these files if the auditing data is not required for recent events.

You can define new audit log file in some other file system with enough space using audsys command.

#audsys -c 150000 -c /path_to_file/new_file_name

Once new file is created you can copy this file to another file system.

Hi Devender
Thanks for your reply. It worked at last..

I havent enabled the auditing as this is only a test server.

Have a nice weekend!!!

Hi Purush,

A better command for looking file consuming space under root only would be

#du -x /|sort -rnk 1 |pg

If the auditing is not required for the system you can turn it off using

#audsys -f

Once stopped you can null out the above two files by

#>/secure/etc/audfile1

#>/secure/etc/audfile2

Also take some time to assign points to the responses for replies of your questions. This will help others to find a solution for similar problems and will also get you prompt responses in future.

Hi Purush,

There is a way to solve this issue without a reboot.

Use Reflection X to establish a "XDMCP Direct" connection to your host. Once you are on check for core files in the / file systems and remove them,
