+#	OCF_RESKEY_devs

+
+#.  This resource agent manages SCSI PERSISTENT RESERVATIONS.
+#.  "sg_persist" from sg3_utils is used, please read its documentation.
+#.  Should be used as multistate (Master/Slave) resource
+#.  Slave registers its node id ("crm_node -i") as reservation key ( --param-rk ) on each device in the "devs" list.
+#.  Master reservs all devices from "devs" list with reservation "--prout-type" value from "reservation_type" parameter.
+#.
+#.	OCF_RESKEY_sg_persist_resource
+#.       ------------------------------
+#.  The name of the sg_persist resource. This parameter is required.
+#.  
+#.	OCF_RESKEY_config_file
+#.      ----------------------	
+#.  Full path to the sg_persist resource configuration file. Default /etc/sg_persist.conf
+#.  Configuration file should be owned by "root" and can only be writable by owner.
+#.  The config file is sourced as shell script with ". \$config_file".
+#.  It should provide a function with a name "sg_persist_resource_\$sg_persist_resource_name"
+#.  which is then called (with no parameters).
+#.  Resorce init functions for several sg_persist resources can be put in one configuration file.
+#.  
+#.  Config file example for sg_persist_resource=MDRAID1:
+#.  ...............................
+#.  sg_persist_resource_MDRAID1() {
+#.      devs="/dev/sdd /dev/sde"
+#.      required_devs_nof=2
+#.  }
+#.  ...............................
+#.
+#.  Configuration file can be used for any resource parameter other then sg_persist_resource and config_file.If some parameter is specified in config file and also as crm resource parameter - the value from crm is used.   
+#.  
+#.
+#.	OCF_RESKEY_devs
+#.      ---------------
+#.  Device list - required, couldn't be empty 
+#.  "echo \$devs" is actually used, so shell wildcars are allowed.
+#.  
+#.	OCF_RESKEY_required_devs_nof
+#.      ----------------------------
+#.  Minimum number of "working" devices from device list "devs": 
+#.      1) existing 
+#.      2) "sg_persist --read-keys \$device" works (Return code 0)
+#.  resorce actions "start","monitor","promote" and "validate-all" return "\$OCF_ERR_INSTALLED" if the actual number of "working" devices is less then "required_devs_nof".
+#.  resorce actions "stop" and "demote" tries to remove reservations and registration keys from all working devices, but always return "\$OCF_SUCCESS"
+#.  Default 1
+#.  
+#.	OCF_RESKEY_reservation_type
+#.      ---------------------------
+#.  reservation type, used for --prout-type option of "sg_persist" command   
+#.  Default 1 - "write exclusive"
+#.  
+#.      OCF_RESKEY_master_score_base
+#.      ----------------------------
+#.  "master_score_base" value is used in "master_score" calculation:
+#.  master_score = \$master_score_base + \$master_score_dev_factor * \$working_devs  
+#.  if set to bigger value in sg_persist resource configuration file on some node, this node will be "preferred" for master role. 
+#.  Default 0
+#.  
+#.	OCF_RESKEY_master_score_dev_factor
+#.      ----------------------------------
+#.  Working device factor in master_score calculation - each "working" device provides additional value to "master_score", so the node that sees more devices will be preferred for the "Master"-role
+#.  Setting it to 0 will disable this behavior. 
+#.  Default 100
+#.
+#.	OCF_RESKEY_master_score_delay
+#.      ----------------------------------
+#.  master decreases its master_score after delay of \$master_score_delay seconds
+#.  slave increases ist master_score after delay of \$master_score_delay seconds
+#.  so if some device gets inaccessible, the slave decreases its master_score first and the resource will no be sweatched
+#.  and after this device reappears again the master increases its master_score first
+#.  this can work only if the master_score_delay is bigger then monitor interval on both master and slave
+#.  Setting it to 0 will disable this behavior.
+#.  Default 30
+
+# TODO
+# 
+# 1) PROBLEM: devices which were not accessible during 'start' action, will be never registered/reserved 
+#    TODO:    'Master' and 'Salve' registers new devs in 'monitor' action
+#    TODO:    'Master' reserves new devs in 'monitor' action
