luci and unfencing when delay set in fence method
Last modified: 2013-02-21 03:22:16 EST
Hi, I've added 'delay' option yesterday in my <fence><method><device> in /etc/cluster/cluster.conf and luci now thinks that I don't have unfence enabled for this device <clusternode name="server1" nodeid="1"> <fence> <method name="server1_san"> <device delay="10" name="san" port="4"/> <device delay="10" name="san" port="5"/> </method> <method name="server1_drac"> <device delay="10" name="fence_drac_server1"/> </method> </fence> <unfence> <device action="enable" name="san" option="enable" port="4"/> <device action="enable" name="san" option="enable" port="5"/> </unfence> </clusternode> <clusternode name="server2" nodeid="2"> <fence> <method name="server2_san"> <device name="san" port="6"/> <device name="san" port="7"/> </method> <method name="server2_drac"> <device name="fence_drac_server2"/> </method> </fence> <unfence> <device action="enable" name="san" option="enable" port="6"/> <device action="enable" name="san" option="enable" port="7"/> </unfence> </clusternode> </clusternodes> ... <fencedevice agent="fence_brocade" ipaddr="xx.xx.xx.xx" login="user" name="san" passwd="pass"/> For server1 it reports: Fence Devices Method server1_san Move Down Remove Name Type/Values san Brocade Switch delay : 10 port : 4 san Brocade Switch delay : 10 port : 5 If you click on "san" then unfencing is not enabled. However unfencing works. When cman starts unfencing is performed. For server2 it reports: Fence Devices Method server2_san Move Down Remove Name Type/Values san Brocade Switch port : 6 unfencing enabled san Brocade Switch port : 7 unfencing enabled regards, Giannis ps. luci-0.23.0-32.el6 cman-3.0.12.1-23

I am not completely sure such config with "delay" would successfully validate (ccs_config_validate, triggered also upon starting the cluster).
Re [comment 14]: Well, it would indeed validate because restrictions based on universal references (e.g., through a custom identifier) and perhaps even based on known attribute value (to be found out) cannot be enforced in RELAX NG schema and the respective validating test is like this: if the set of attributes w/o "name" is a subset of attributes sets defined for particular fence agents, then the result of this validation part is OK In the case in [comment 0], it will pass because this condition holds, for example for the set of attributes defined for "fence_apc" (which includes both "port" and "delay"). As a consequence, I filed a new bug in the current "semantic validation" wave: [bug 909133].
