Description Cedric Buissart 2015-09-13 16:44:06 UTC

Description of problem:

In RHEL7 / systemd, the /etc/sysconfig/glusterd file is not being read. As a consequence, we can not override options.
In particular, LOG_LEVEL would be handy.

Version-Release number of selected component (if applicable): RHGS 3.1 on RHEL7


How reproducible: 100%


Steps to Reproduce:
1. Install RHGS 3.1 on RHEL7
2. edit /etc/sysconfig/glusterd : LOG_LEVEL=TRACE
3. systemctl start glusterd.service

Actual results:
We are still in default logging level


Expected results:
debug level


Additional info:
systemd has a 'EnvironmentFile' entry that can be used to read /etc/sysconfig/glusterd.

Comment 2 Anand Nekkunti 2015-09-14 10:14:15 UTC

We need to set environment variable in service file (/usr/lib/systemd/system/glusterd.service file) 

1).Set environment variable
EnvironmentFile=/etc/sysconfig/glusterd    

2). Pass LOG_LEVEL to ExecStart
ExecStart=/usr/sbin/glusterd -p /var/run/glusterd.pid $LOG_LEVEL

This Bug verified with the rhgs ver: 3.1.2 ( glusterfs-3.7.5 ).

Found that Fix is working correctly and it's reading the /etc/sysconfig/glusterd file for log_level.

Step done before moving to verified state:
==========================================
1. Have one node with 3.1.2 build (glusterfs-3.7.5)
2. Edited the /etc/sysconfig/glusterd file.
 

[root@ ~]# cat /etc/sysconfig/glusterd 
## Set custom log file and log level (bellow are defaults)
LOG_FILE='/var/log/glusterfs/glusterd.log'
LOG_LEVEL='TRACE'

## Set custom options for glusterd
# GLUSTERD_OPTIONS=''
[root@ ~]# 

3. restarted the glusterd (systemctl restart glusterd.service)
4. Created one plane distributed volume
5. Checked the glusterd log, below is log details after above steps.
