Hi,
Using corosync 1.4.2 (debian backports) and have noticed that if one
messes up corosync.conf in the logging section it still works, but not
as expected.
For example I had
logging {
fileline: off
to_stderr: yes
to_logfile: yes
to_syslog: /var/log/corosync/corosync.log
to_syslog: no
syslog_facility: daemon
debug: off
timestamp: on
logger_subsys {
subsys: AMF
debug: off
tags: enter|leave|trace1|trace2|trace3|trace4|trace6
}
}
Used to_syslog twice instead of logfile and to_syslog. Corosync
started without any errors, and without any logs.
to_syslog accepts only yes|no. The first entry would set to default (no
IIRC) and the second one would override the first entry and set it to
"no" (for sure). Default log file is set to
/var/log/cluster/corosync.log. If /var/log/cluster doesn't exists, it
would fail to open the log file (aka no logs again).
Probably should bail early, maybe do some syntax checking.
Just saying.
Patch? ;)
The idea is nice, there is no doubt about it, but it's almost "mission
impossible" given the complexity (and not just for logging). Not sure
maybe Jan has an idea how to fix it easily.
Have augeas run the parser over it in the init script?
So I just ran this on my config I had.
augtool ls /files/etc/corosync/
augtool ls /augeas/files/etc/corosync/corosync.conf/error
I get:
pos = 46
line = 2
char = 0
lens = /usr/share/augeas/lenses/corosync.aug:179.10-.81:
message = Iterated lens matched less than it should
So looking at line 2: I had compatibility in my config
I removed that.
augtool ls /files/etc/corosync/corosync.conf/
#comment = Please read the corosync.conf.5 manual page
totem/ = (none)
logging/ = (none)
quorum/ = (none)
Then changed to your logging config:
to_logfile = <filename>
to_logfile = no
augtool ls /files/etc/corosync/corosync.conf/
augtool ls /augeas/files/etc/corosync/corosync.conf/error
pos = 1872
line = 51
char = 0
lens = /usr/share/augeas/lenses/corosync.aug:179.10-.81:
message = Iterated lens matched less than it should
line 51 points to the top of the logging section.
I have to say the output is not particularly user friendly.
But it does check the syntax, and it can be figured out.
