Description Marian Ganisin 2015-08-26 10:10:24 UTC

Description of problem:

During upgrade I see following message:

warning: %postun(mcelog-3:101-3.9de4924.el7.x86_64) scriptlet failed, exit status 1


I briefly checked rpm scriptelts of mcelog-120-2.e7e0ac1.el7.x86_64.rpm (not the same version!) this piece of code might cause it:

# Handle upgrading mcelog
if [ "$1" -ge 1 ]; then
        systemctl try-restart mcelog.service &> /dev/null
fi


This does not seem to be a big issue. Anyway it could be good to have this covered. Simple modification might do the job:

# Handle upgrading mcelog
if [ "$1" -ge 1 ]; then
        systemctl try-restart mcelog.service &> /dev/null || :
fi

Version-Release number of selected component (if applicable):
mcelog-3:101-3.9de4924.el7.x86_64

How reproducible:
upgrade of package (I did yum update)

Actual results:
rpm reports warning from postun

Expected results:
real issue fixed, harmless hidden

I just did

yum -y install mcelog (to get the latest released mcelog in 7.1) and followed that by a "manual" rpm -Uvh of the mcelog package from 7.2

I do *not* see this error.  Is there some magic to force this error?

The mcelog.service has to be started, systemctl start mcelog.service after yum install is necessary.

Anyway I found that it does not seem to be possible to stop mcelog.service gracefully at all. Whenever I do systemctl stop mcelog.service it enters failed state due to returned exit-code:

● mcelog.service - Machine Check Exception Logging Daemon
   Loaded: loaded (/usr/lib/systemd/system/mcelog.service; enabled; vendor preset: enabled)

So systemctl stop mcelog.service might be real cause of this issue.

Comment 4 Martin Poole 2016-07-17 11:12:05 UTC

Would appear to need the '|| :' on all the systemctl entries (install & uninstall).

Tried that and it didn't work.  I think the issue is that the mcelog utility can return 15 as "SUCCESS" on shutdown, and that systemd expects to see 0.

mganisin, can you modify /usr/lib/systemd/system/mcelog.service

to include the SuccessExitStatus line below

[Service]
Type=forking
ExecStartPre=/etc/mcelog/mcelog.setup
ExecStart=/usr/sbin/mcelog --ignorenodev --daemon --syslog
SuccessExitStatus=0 15
StandardOutput=syslog

and try your test again?

Thanks,

P.
