* ctdb-recoverd: Move ctdb_ctrl_modflags() to ctdb_recoverd.cMartin Schwenke2020-08-271-5/+0

* ctdb-daemon: Add extra logging of hot keysMartin Schwenke2020-05-221-0/+1
| | | | | | | | | | | ctdbd currently only logs when a new hot key is added. If a key gets hotter then nothing new is logged. Log hot key updates when the number of migrations has doubled since the last time that key was logged. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>
* ctdb-daemon: Add separate hot keys array for database statisticsMartin Schwenke2020-05-221-0/+6
| | | | | | | | | | There are 2 reasons for this. Sorting of hot keys is broken and will be changed to an implementation that needs a named (i.e. not anonymous) structure. Also, at least one non-protocol field will be added to facilitate more useful logging. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>

* ctdb-daemon: Replace function ctdb_ip_to_nodeid() with ctdb_ip_to_pnn()Martin Schwenke2019-07-051-1/+2
| | | | | | | | | | | Node ID is a poorly defined concept, indicating the slot in the node map where the IP address was found. This signed value also ends up compared to num_nodes, which is unsigned, producing unwanted warnings. Just return the PNN because this what both callers really want.

| | | | | | | | | | | | | | | | The comment immediately above this code says "don't allow local clients to attach" and then looks up the client ID regardless of whether the request is local or remote. This means that an intentional remote attach from a client will not work correctly. No real client should ever do that since clients attach so they an access databases locally. Perhaps some sanity checks should be added. BUG: https://bugzilla.samba.org/show_bug.cgi?id=13500 Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>

* ctdb-locking: Reduce logging in case of contentionAmitay Isaacs2017-06-191-0/+3
| | | | | | | | | | | | | | | Currently, every lock helper will log a message if it cannot get a lock. This can spam the logs and overwhelm syslog if there are hundreds of lock helpers waiting for contended record. Instead keep track of the record for which we have already logged once with specific timeout interval. If we get timeout interval larger than the previously logged interval, then log again once. This will reduce the amount of logs for contended records to a single log entry per 10 seconds per record.
