savecore.LCK

[Generic User OI IIS]

Hi Admins,

Here's a strange occurence with a K-class node. Everytime we boot this machine a coredump is made. Her is the info from /etc/rc.log :

Save system crash dump if needed
Output from "/sbin/rc1.d/S440savecrash start":
----------------------------
savecrash: Found old-format dump, invoking /usr/old/sbin/savecore
savecore: Invalid /etc/savecore.LCK file from previous run.
Dump may be corrupted.
savecore: dump previously saved
EXIT CODE: 2 - savecrash found no core dump to save
"/sbin/rc1.d/S440savecrash start" SKIPPED

This weird occurence started after I installed HP 11.00 on the box again. I suspect there's a flag hanging somewhere on the bootdisc.

Can someone help me out ?

TIA,

Willy,

It looks like the system thinks there needs to be a dump made.

Try booting in single user mode and run this command:

# savecore -c

from man savecore:

-c Mark the dump in the dump device as saved, without performing any other action. The -c option is useful for manually inhibiting dump actions called
by /sbin/init.d/savecore.

Now reboot the system again !

I agree with Clemens, you have an old dump marked for saving, and you can clear it by doing savecore -c

Once this has been done, you can try to run
/sbin/rc1.d/S440savecore start
and see if this still reports a dump is there. If not, no need to reboot.

Thanks so far. However we have allready done this, from that moment on, we get the message above. Before we performed the "savecore -c" command, the system actually made a dump in /var/adm/crash. But the next reboot the system tried to make another dump with the same message; "Found old-format dump, invoking ... etc.."

Any other suggestions?

Hi,

Maybe since the upgrade or install to 11.00 you need to use savecrash -c instead of savecore -c.

This has been changed between versions.

Hi,

Another more definite solution would be to do a TOC dump to have the old dump format overwritten.

a TOC will overwrite the information on the DUMP device which should be in 11.00 format.

Keep all user file systems unmounted before doing a TOC. Also, have a backup from the system.

If the file /etc/savecore.LCK is on the system.
Do stings /etc/savecore.LCK
Also remove this file.

Hi Clemence,
Thanks, forcing a TOC did the job. After this the system doesn't report any old dumps anymore.

Best regards,
Addie.

Addie,

Good to hear the solution works.
