Results will be written to an attribute with leading slashes removed, and other slashes replaced with underscore, and the word 'free' appended - e.g for /dev/sda1 it would be 'dev_sda1_free'. Note: The root filesystem '/' is always queried to an attribute named 'root_free' List of Filesytems/Paths to query for free disk space Unit to report disk free space in. Can be one of: B, K, M, G, T, P (case-insensitive) Unit to report disk free space in The amount of free space required in monitored disks. If any of the monitored disks has less than this amount of free space, , with the node attribute "#health_disk" changing to "red", all resources will move away from the node. Set the node-health-strategy property appropriately for this to take effect. If the unit is not specified, it defaults to disk_unit. minimum disk free space required END } ####################################################################### UpdateStat() { name="$1"; shift value="$*" printf "%s:\t%s\n" "$name" "$value" if [ "$__OCF_ACTION" = "start" ] ;
