[SOLVED] Kdump error during post installation configuration
[SOLVED] Kdump error during post installation configuration
Hello all,
After successfully installing Centos 6, i rebooted my PC. But, during the post-install configuration, the last item i.e, Kdump failed. I got message - insufficient memory.
And it showed me the Kdump config window with all options disabled, and nothing was happening. So, i forced rebooted my PC. Now, i directly got the login prompt & am posting this message from the newly installed Centos.
Will i have any problem due to the erroneus Kdump post-install configuration?
(I have 1.2 GB Ram & after installation i have 10 GB free partition space)
Thanks!

[SOLVED] Kdump error during post installation configuration
Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature.
The kdump failure is known and is more of a cosmetic issue than a real problem, as explained in the [url=http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.0#head-710e17fe8ed8c98a1fe4faee4e11e2135df09fff]Release Notes section 4[/url]. Forcing a reboot is [b]always[/b] a bad idea unless there is no alternative, and I don't know what installation steps you may have skipped by doing so, but if things seem to be working correctly you are probably OK.

Re: Kdump error during post installation configuration
c'mon dont make me feel more bad. i knew it was bad idea, but nothing was working. It got hanged. I tried Cltrl_Alt_F1, still nothing. Had to do that.
Well, so far things are running fine.
The release note asks to update kexec-tools to kexec-tools-2_0_0-153_el6 or newer
When i try,
yum install kexec-tools
I get
Package kexec-tools-2.0.0-145.el6.i686 already installed and latest version
When i try
yum update kexec-tools
I get
No Packages marked for Update

Then you had some problem other than the kdump error, which does not cause a hang.

That is correct. No update has been released for CentOS-6. 6.1 will have kexec-tools-2.0.0-188.el6. Added a clarification to the release notes.

Re: Kdump error during post installation configuration
ok. But, my basic query still remains. How do i check if i will not have any problem due to interrupted post-install config. In the post-install config dialog, the kdump config was last one as i remember, i dont know what should have happened after that.
Like there are disk check utility before installation. Is there any way to check whether my installation & all configs are proper. Or will i have to just wait and watch for something to go wrong?

Re: Kdump error during post installation configuration
Here is something you can try. It is an old technique but I see the responsible code is still available for [i]RHEL 6.x[/i], so it should work for [i]CentOS 6.0[/i]. Please assume [i]root[/i] powers, then --
[code]
[b]touch /.unconfigured
shutdown -r now[/b]
[/code]
[code]
[b]touch /.unconfigured
shutdown -r now[/b]
[/code]

Hi,
I tried out those commands.
After boot, it performed text-based configuration.
*Keyboard
*root password
Then it asked to choose from device config or DNS.., i chose device config
It then displayed two column list, with screen title being "Authentication configuration. "
Left column was titled 'user input': it had few entries, but none were selected. I left it as that
Right column was titled 'Authentication' : Out of the list, 'Use Shadow Password', 'Use Fingerprint reader', 'Local authorization is sufficient' were already selected. I removed the fingerprint one
Next page was for 'which services to be auto started on boot'. Many were listed, and some were already selected. I removed 'bluetooth'.
After that i got the normal GUI login prompt.
Dont know if this is what was supposed to happen behind the gui-based post-install config that had been interuppted.
Also, there was no kdump config as was in the post-install config.
I am not keen on having the kdump configured. But, i would like to rectify anything if at all, so things like [url=https://www.centos.org/modules/newbb/viewtopic.php?topic_id=32836&forum=57]no audio[/url] do not creep up.

With [i]root[/i]'s powers, edit your [b]/etc/grub.conf[/b] file and change the existing parameter on each "kernel" line, [b]crashkernel=[i]somevalue@something[/i][/b], to be [b]crashkernel=no[/b]. Once that is done, a crash kernel is then not configured.

Re: Kdump error during post installation configuration
Thank-you for helping me resolve the interrupted configuration.
I have changed the crashkernel=auto option to crashkernel=no.
Can you please help me out in fixing my [url=https://www.centos.org/modules/newbb/viewtopic.php?topic_id=32836&forum=57]no audio[/url] problem.

I have read your other thread but I do not have any suggestion. Sorry.
Perhaps someone else may have an idea for what you can try.
