Ronnie Sahlberg	c6bd23ee11	update to rhe recovery daemon ... ctdb_ctrl_ calls are timedout due to nodes arriving or leaving the cluster it crashes the recovery daemon afterwards with a SEGV but no useful stack backtrace (This used to be ctdb commit cd3abc7349e86555ccd87cd47a1dcc2adad2f46c)	2007-05-06 06:58:01 +10:00
Ronnie Sahlberg	7dfdab1b9d	recovery daemon ... this program is a client to the local ctdb daemon every second it pulls all vnnmap and nodemaps from all nodes that are available and checks if a recovery is required a recovery is required if : * all nodes do NOT have an identical vnnmap and generation * all nodes do NOT have an identical nodemap * there are active nodes that are NOT in the nodemap * there are nodes in the nodemap that are NOT active During recovery, the recovery tool will also make sure that all nodes know about and have created all databases.

Ronnie Sahlberg	b3c8d6ea7a	also verify that the generation id is the same on all the nodes and if ... not, trigger a recovery (This used to be ctdb commit 46b8a66ee70419c153acf45eeec88c1fc8f230ce)	2007-05-04 11:57:45 +10:00
Ronnie Sahlberg	2b1714a521	update getvnnmap control to take a timeout parameter ... dont explicitely free the vnnmap pointer in the getvnnmap control this is freed by the mem_ctx instead add code to the recoverd to detect when/if recovery is required veiry that the number of active nodes, the nodemap and the vnn map is consistent across the entire cluster and if not trigger a recovery (which right now just prints "we need to do recovery" to the screen.

Ronnie Sahlberg	ae73784c28	change the signature for ctdb_ctrl_getnodemap() so that a timeout ... parameter is added. change ctdb_get_connected_nodes in the same way (This used to be ctdb commit d85f23bcf4c1230225abb2f4a053c70b68d469aa)	2007-05-04 09:01:01 +10:00
Ronnie Sahlberg	ebc478749b	start working on a recovery daemon ... change ctdb_control so it takes a timeval pointer as argument. this is the timeout. if the node has not responded within hte timeout ctdb_control will return an error instead of hanging. if the timeval pointer is NULL then the call will block indefinitely if there is no response. this is used for now in the createdb control but all the helpers ctdb_ctrl_* should probably be updated to take a timeout parameter as well.
