Resolved plesk component installer hangs at Running rpm_check_debug

[Pan_Duke]

Hi all,

had a problem with fail2ban, it couldn't start and plesk starting page was taking too long to load. it stayed like this for a couple of weeks so tonight i decided to uninstall fail2ban and install it again. so i clicked on add remove components and selected it for removal at the "Install or Upgrade Odin Products" page.
now the proccess hanged at Running rpm_check_debug.
plesk couldn't open meanwhile

i tried
/etc/init.d/psa stopall
/etc/init.d/psa start

plesk working again. logged in, clicked add remove and there it is still hanging there

here is the log :

You can try to yum remove fail2ban

 

[Pan_Duke]

well the installer is still active and in many threads about f2b and plesk they suggest working with it via plesk (installing, starting stopping etc)

besides this morning i found that the installer logged a new message

how can i stop this ?

You should kill autoinstaller/installer and yum_install processes first with TERM, then with KILL signals

 

[Pan_Duke]

thank you for your answer.
is there a safe way to do that?
tryied to follow this article but with no success

Plesk autoinstaller uses yum for installing rpm packages, and it seems it hangs inside of yum. KB-121921 does not help, as it describe slightly different situation You should perform next action to solve this.
1. Kill current autoinstaller and yum_install processes. Run ps xaf | grep -C4 "installer\|yum" | grep -v grep to find its PIDS. Output should looks like:

# ps xaf | grep -C4 "installer\|yum_install" | grep -v grep

The interested lines contains words yum or yum_install and autoinstaller or installer. First column in output it's their PID files.

2. Attempt to soft stop this processes with next command (I got pids from previous output, you should got your own):
kill -TERM 5848 5947

3. If processess still exists (check that in 1.) we will hard stop of it:
kill -KILL 5848 5947

4. Also, you may rebuild rpm database. See http://kb.odin.com/en/124100 for details, or do next steps:

# cp -rfv /var/lib/rpm /var/lib/rpm.backup
# rm -rf /var/lib/rpm/__db.*
# rpm --rebuilddb -vv

If you have troubles with determining pid file post your ps xaf | grep -C4 "installer\|yum" | grep -v grep or send me private message with it

 

[Pan_Duke]

thank you again!
i got the PID but i see 3 fail3ban lines as well so i thought i better post it here before ... killing

so should i just :
kill -TERM 24345
or better kill all "fail2ban stop"?

 

[mizar]

It's better kill "fail2ban-client stop" and also "fail2ban-client status". And if you do this, you don't need to kill yum_install or autoinstaller or rebuild rpm database

 

[mizar]

BTW, do you see something suspicious in /var/log/fail2ban.log ?

 

[Pan_Duke]

Greaaat!! Killed them all and the installation continued and finished!

thanx a million Mizar!

EDIT No nothing suspicious. what could it be suspicious...? The only thing is that the last log is 8 September, the day it stopped working....
