Cannot Access CP After update 9.2.x to 9.2.3

[Ritey]

Hi

This is regarding plesk on linux fc

I have started an update from CP as normal. And i got the initial success email sent back. But after that i cannot access the CP. And when i log into the server with ssh, the port 8443 is not listening when i use netstat. And also it appears that the autoinstaller is still running. It has been running for about an hour now and the following are still in the process list:-

root 5647 0.0 1.7 127692 72372 ? Ss 09:37 0:03 /usr/local/psa/admin/bin/autoinstaller --enable-xml-output --
root 5648 0.0 0.0 0 0 ? Z 09:37 0:00 [autoinstaller] <defunct>
root 7156 0.0 1.7 127692 69156 ? S 09:39 0:00 /usr/local/psa/admin/bin/autoinstaller --enable-xml-output --

root 8661 0.0 0.1 9928 4644 ? S 09:39 0:00 /bin/sh /var/tmp/rpm-tmp.9387 2
root 9199 0.0 0.0 2780 652 ? D 09:39 0:00 chmod -R 644 /usr/local/psa/admin/htdocs/locales

It is now 10:43 GMT so obviously something is stuck.

Please help!!!!

Look at /tmp/autoinstaller3.log
Is there something useful?

Unfortunately I have rebooted the server as it was the only way I could stop the thing. So the autoinstaller log just contains stuff i tried since.

I did fine out that this was probably the process causing the hang...

chmod -R 644 /usr/local/psa/admin/htdocs/locales

As when i tried it, it gave same result. It never ended. Even with kill -9. Took a reboot to stop it.

Now i have the the CP listening on 8443, but when accessing the server it gives http 500 Internal Server error. Which is presumably because the previous upgrade attempt failed. So there is a miss match of stuff in the installation at the moment.

The mail and web and all else seems to be running ok. But without CP i am pretty blind.
I even managed to perform a plesk backup without problem.

So what i need to know now is what is the best way of returning to a usable state?

A little more poking around in logs.
This is from the syslog at around the same time....

So it seems that it is the chmod. "lock help at task exit time!"

Hmm... According google seems it is kernel bug. Did you tried upgrade kernel there? Not sure that it is Plesk related issue. I can suggest you also try to install psa packages with something like 'rpm -Uvh --force --nodeps psaxxxx.rpm'
All necessary default chowns and chmods will be applied correctly and maybe it will help too.

 

[Ritey]

Thanks for looking at that. I did try the rpm but with --force, did not use --nodeps. And that would explain why i got dependency errors when i tried.

I will try that first. Failing that i will re-image the server. It seems that my host (1and1) has droped FC4 in favour of centos/plesk 9.

That being the case, i have successfully made a full plesk backup (even though it was after the problem). Is restoring my data to a new install of plesk on a new OS, just a case of the pleskrestore utility? If so then hopefully that will cure the kernel bug issue also.

 

[Ritey]

Thanks your advice worked. I now have my plesk CP back!
I think i will possibly leave the re image until i refill my fridge with beer.

Thanks for your help!
