Not an answer, but curiosity: As sbd needs very little space (like just 1MB), did anybody ever try to use a small computer like a raspberry pi to privide shared storage for SBD via iSCSI for example? The disk could be a partition of the flash card (it's written quite rarely). ... > After some long timeout, it looks like the watchdog timer expires and server > boots, but the failure indication remains on the front panel of the server. Dell PowerEdge? ;-) In SLES I have these (among others) settings: SBD_WATCHDOG_DEV=/dev/watchdog SBD_WATCHDOG_TIMEOUT=30 SBD_TIMEOUT_ACTION=flush,reboot I did: h16:~ # echo iTCO_wdt > /etc/modules-load.d/watchdog.conf h16:~ # systemctl restart systemd-modules-load h16:~ # lsmod | egrep "(wd|dog)" iTCO_wdt 16384 0 iTCO_vendor_support 16384 1 iTCO_wdt Later I changed it to: h16:~ # echo ipmi_watchdog > /etc/modules-load.d/watchdog.conf h16:~ # systemctl restart systemd-modules-load After reboot there was a conflict: Dec 04 12:07:22 h16 kernel: watchdog: wdat_wdt: cannot register miscdev on minor=130 (err=-16). Dec 04 12:07:22 h16 kernel: watchdog: wdat_wdt: a legacy watchdog module is probably present. h16:~ # lsmod | grep wd wdat_wdt 20480 0 h16:~ # modprobe -r wdat_wdt h16:~ # modprobe ipmi_watchdog h16:~ # lsmod | grep wat ipmi_watchdog 32768 1 ipmi_msghandler 114688 4 ipmi_devintf,ipmi_si,ipmi_watchdog,ipmi_ssif h16:/etc/modprobe.d # cat 99-local.conf # # please add local extensions to this file # h16:/etc/modprobe.d # echo 'blacklist wdat_wdt' >> 99-local.conf Maybe also check whether „echo V >/dev/watchdog“ will stop the watchdig properly. SUSE (and upstream meanwhile Iguess) had to fix it. Hope this helps a bit.
