如何使用 Intel 6300esb 设置 Linux 看门狗守护进程

如何使用 Intel 6300esb 设置 Linux 看门狗守护进程

我已经在 Google 上搜索了这个问题一段时间了,但还没有找到关于如何将我的 6300esb 看门狗定时器的内核驱动程序连接到 /dev/watchdog 并确保看门狗守护进程保持其处于活动状态的正确文档。

顺便说一下,我在 KVM 虚拟机中使用与 RHEL 兼容的 Scientific Linux 6.3

以下是我迄今为止尝试过的一切:

dmesg|grep 6300
i6300ESB timer: Intel 6300ESB WatchDog Timer Driver v0.04
i6300ESB timer: initialized (0xffffc900008b8000). heartbeat=30 sec (nowayout=0)

ll /dev/watchdog
crw-rw----. 1 root root 10, 130 Sep 22 22:25 /dev/watchdog

|

/etc/watchdog.conf

#ping           = 172.31.14.1
#ping           = 172.26.1.255
#interface      = eth0
file            = /var/log/messages
#change         = 1407

# Uncomment to enable test. Setting one of these values to '0' disables it.
# These values will hopefully never reboot your machine during normal use
# (if your machine is really hung, the loadavg will go much higher than 25)
max-load-1      = 24
max-load-5      = 18
max-load-15     = 12

# Note that this is the number of pages!
# To get the real size, check how large the pagesize is on your machine.
#min-memory     = 1

#repair-binary      = /usr/sbin/repair
#test-binary        = 
#test-timeout       = 

watchdog-device = /dev/watchdog

# Defaults compiled into the binary
#temperature-device =
#max-temperature    = 120

# Defaults compiled into the binary
#admin          = root
interval        = 10
#logtick                = 1

# This greatly decreases the chance that watchdog won't be scheduled before
# your machine is really loaded
realtime        = yes
priority        = 1

# Check if syslogd is still running by enabling the following line
#pidfile        = /var/run/syslogd.pid   

现在也许我没有正确地测试它,但我预计停止看门狗服务会导致 /dev/watchdog 在 30 秒后超时,并且我应该看到主机重新启动,但这并没有发生。

另外,这是我的 KVM 虚拟机配置

任何帮助都将不胜感激,因为我发现最多的是 kvm 补丁和通用 softdog 文档或 IPMI 看门狗答案。
