9 Troubleshooting #
Booth uses the same logging mechanism as the CRM. Thus, changing the log level will also take effect on booth logging. The booth log messages also contain information about any tickets.
Both the booth log messages and the booth configuration file are included in
the crm report.
In case of unexpected booth behavior or any problems, check the logging data
with sudo journalctl -n or create a detailed cluster
report with crm report.
In case you can access the cluster nodes on all sites (plus the arbitrators)
from one single host via SSH, it is possible to collect log files from all of
them within the same crm report. When calling crm
report with the -n option, it gets the log files
from all hosts that you specify with -n. (Without
-n, it would try to obtain the list of nodes from the
respective cluster). For example, to create a single crm
report that includes the log files from two two-node clusters
(192.168.201.111|192.168.201.112 and
192.168.202.111|192.168.202.112) plus
an arbitrator (147.2.207.14), use the following command:
# crm report -n "147.2.207.14 192.168.201.111 192.168.201.112 \
192.168.202.111 192.168.202.112" -f 10:00 -t 11:00 db-incidentIf the issue is about booth only and you know on which cluster nodes (within a site) booth is running, then specify only those two nodes plus the arbitrator.
If there is no way to access all sites from one host, run crm
report individually on the arbitrator, and on the cluster nodes of
the individual sites, specifying the same period of time. To collect the log
files on an arbitrator, you must use the -S option for
single node operation:
amsterdam # crm report -f 10:00 -t 11:00 db-incident-amsterdam berlin # crm report -f 10:00 -t 11:00 db-incident-berlin arbitrator # crm report -S -f 10:00 -t 11:00 db-incident-arbitrator
However, it is preferable to produce one single crm report
for all machines that you need log files from.
