We've had a few instances where x86 and CHR instances have locked up...
The following are steps on how to set up IPMI watchdog capabilities on relatively old RHEL6 (also CentOS 6) systems. Hopefully Mikrotik could relatively easily incorporate this:
Code: Select all
yum -y install watchdog;
pico /etc/watchdog.conf;
watchdog-device = /dev/watchdog
interval = 25
realtime = yes
priority = 1
chkconfig --level 3 watchdog off; # Yes, off
yum -y install ipmitool;
#deps: OpenIPMI OpenIPMI-libs
modinfo ipmi_watchdog;
# Details available options
pico /etc/sysconfig/ipmi;
IPMI_WATCHDOG=yes
IPMI_WATCHDOG_OPTIONS="timeout=60 start_now=1 preop=preop_give_data actio
n=power_cycle pretimeout=1"
chkconfig --level 3 ipmi off; # Yes, off
pico /etc/rc.d/rc.local;
# Start the IPMI reset timer and watchdog
service ipmi start;
service watchdog start;
