| | * | IP allocation simulation - add -H/-S options for hard/soft imbalance limit.Martin Schwenke2011-07-291-10/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An imbalance exceeding the hard limit, as specified by -H (and defaulting to 1), now causes termination when -x is specified. Imbalances exceeding the soft limit, as specified by -S (and defaulting to 1), are counted and printed in the statistics summary. A side-effect is that imbalances less than 2 are no longer rounded down to 0, since we want to see them in the stats.

| * | Eventscripts - 10.interfaces should not check orphaned interfaces.Martin Schwenke2011-08-021-8/+5
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the last IP address on an interfaces is removed then that interfaces should no longer be checked by 10.interfaces. However, "ctdb ifaces" still lists such interfaces so they are currently checked. The problem really needs to be addressed in ctdbd but a neat quick eventscript fix will be minimally invasive... This changes the code to use "ctdb -Y ip -v" instead of "ctdb -Y ifaces". The former includes details of all public addresses and associated interfaces, so when an address is removed there is no output for it. This avoids orphaned interfaces from being listed. The logic is also slightly improved so that $IFACES includes just a (non-uniquified) list of interfaces, allowing an existing loop to be removed.

| | * IP allocation - add LCP2 algorithm.Martin Schwenke2011-07-293-106/+537
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current non-deterministic IP allocation algorithm balances IPs across the whole cluster. It does not consider different interfaces/VLANs/subnets, so these different groups of IPs aren't generally well balanced. This adds the LCP2 algorithm for IP allocation and allows it to be enabled by setting the "LCP2PublicIPs" tunable to 1. The LCP2 algorithm calculates the imbalance of a node by totalling the squares of the distances between each IP on the node. The IP distance is defined as the length longest common prefix (LCP) of bits that is found when comparing 2 IPs. The imbalance of a cluster is the maximum imbalance for any node. At each step the algorithm selects an allocation to the IP/node combination that results in the choosing the allocation that best reduces the imbalance of the cluster. The implementation splits out the IP allocation part of ctdb_takeover_run() into new function ctdb_takeover_run_core(), and then extracts out the basic IP assignment code into new functions basic_allocate_unassigned() and basic_failback(). 3 new functions lcp2_init(), lcp2_allocate_unassigned() and lcp2_failback() implement the LCP2 algorithm, and are hooked into ctdb_takeover_run_core().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ctdb_event_script_callback() takes a mem_ctx arg which it doesn't use, but the implication is pretty clear, that when that mem_ctx is freed, the callback shouldn't happen. Indeed, Ronnie reproduced a case where that callback refers to freed memory, in the ip reallocation code under stress. So attach the callback to the mem_ctx they give us, and remove it from the script state structure when that's freed. It's a bit weird, but it works.
