Description
RAD team bot copy to z-stream
2020-04-23 09:45:04 UTC
Reproducing the issue :
========================
Register and subscribe the system
with virt-who /rhsmd running
Steps 1: Make virt-who /rhsmd running ;
============================
#service virt-who restart and
# /usr/libexec/rhsmd -k in terminal
Step 2 : execute some sub-man commands to create log entries
=============================================
[root@kvm-06-guest10 rhsm]# subscription-manager remove --all
1 local certificate has been deleted.
1 subscription removed at the server.
Step 3 : force logrotate to run
======================
[root@kvm-06-guest10 rhsm]# logrotate -f /etc/logrotate.conf
[root@kvm-06-guest10 rhsm]# ls
rhsmcertd.log rhsmcertd.log-20200422 rhsm.log rhsm.log-20200422
^^ notice "rhsm.log-20200422" is now created
Step 4: Grep for open files
===================
[root@kvm-06-guest10 rhsm]# sudo lsof | grep deleted | grep rhsm
rhsmd 21406 root 6u REG 253,0 4096 100709773 /tmp/ffib6dPFX (deleted)
[root@kvm-06-guest10 rhsm]# rm -rf rhsm.log-20200422
^^ Delete the file
[root@kvm-06-guest10 rhsm]# sudo lsof | grep deleted | grep rhsm
rhsmd 21406 root 4w REG 253,0 20908 34568341 /var/log/rhsm/rhsm.log-20200422 (deleted)
