Ian Barwick	c907b7b33d	repmgr: minor fix to "repmgr standby --help" output	2017-11-15 14:04:01 +09:00
Ian Barwick	31b856dd9f	Add "witness register" functionality	2017-11-15 14:03:54 +09:00
Ian Barwick	d459b92186	Add configuration file "passfile" ... This will enable a custom .pgpass to be included in "primary_conninfo" (provided it's supported by the libpq version on the standby).	2017-11-15 14:03:37 +09:00
Ian Barwick	11d856a1ec	"standby follow": get upstream record before server restart, if required ... The standby may not always be available for connections right after it's restarted, so attempting to connect and get the node's upstream record after the restart may fail. Record is now retrieved before the restart. Addresses GitHub #333.	2017-10-27 16:30:25 +09:00

Ian Barwick	30b11c08e6	Disable any configuration settings not compatible with PostgreSQL 9.3 ... And emit a warning while we're at it.	2017-09-18 13:12:38 +09:00
Ian Barwick	ea2693bc75	Move create_recovery_file() et al to repmgr-action-standby.c ... As they're only ever called from there.	2017-09-18 09:53:08 +09:00

Ian Barwick	e040f95aaa	"standby clone": fix replication slot generation ... Slot on source node was being deleted even if source node is the intended upstream node.	2017-09-14 08:47:56 +09:00

Ian Barwick	b6a27b975d	"standby clone": improve handling when designated upstream doesn't yet exist ... This situation can occur in provisioning environments, where a node's upstream may not exist at the point it's cloned. If replication slots are in use, we'll need to make sure no attempt is made to create the replication slot on the designated upstream, as that will end in tears. We assume the user will be prepared to complete this step manually.	2017-09-07 12:35:27 +09:00
Ian Barwick	3787dd3795	"standby switchover": better handling of remote execution failure	2017-09-07 11:50:56 +09:00
Ian Barwick	edee80cc37	Rename option "node check --is-shutdown" to "--is-shutdown-cleanly" ... As that's what we really want to know. Also return "UNCLEAN_SHUTDOWN" if that's the case, rather than "RUNNING" which is confusing, even though it's a command for internal use.	2017-09-07 11:15:27 +09:00
Ian Barwick	79531ae9da	"standby switchover": fix check for remote repmgr binary ... Also add a useful hint about setting "pg_bindir".	2017-09-07 10:26:46 +09:00

Ian Barwick	a28bbd68eb	"standby clone": improve replication slots handling ... Ensure replication slot is created on the upstream node and deleted from the source node, if upstream node and source nodes differ.	2017-09-06 12:16:02 +09:00
Ian Barwick	bd07a34472	"standby clone": improve log messages ... Make it clearer which nodes are being connected to, and why.	2017-09-06 10:15:52 +09:00
Ian Barwick	5b5b456ecb	"standby switchover": improve logging ... Also no need to disconnect/reconnect from/to local node while it promotes.	2017-09-05 10:26:27 +09:00
Ian Barwick	d82e936556	"standby promote": improve logging ... Specifically state which server is being promoted; this is particularly important when the promotion occurs as part of a series of other operations, e.g. "standby switchover". Also no need to disconnect/reconnect while the server is promoted.	2017-09-05 09:43:16 +09:00
Ian Barwick	78e6bdeebe	Have repmgrd parse "standby follow --upstream-node-id=%n"	2017-09-04 13:42:50 +09:00
Ian Barwick	47a4b49890	Add "repmgr standby follow --upstream-node-id" ... In an automatic failover situation, after a standby has been promoted there's a risk the original primary may become available again before "standby follow" is issued on another standby node, in which case "standby follow" will reconnect to the original primary. As the standby's repmgrd will have received a notification from the new primary, it will know the primary's ID and can therefore explicitly direct "standby follow" to follow that primary.	2017-09-04 09:11:59 +09:00
Ian Barwick	3aeceab081	"standby follow": add missing sleep() call when --wait specified	2017-09-02 13:11:03 +09:00

Ian Barwick	0e0b221507	Add configuration file setting "use_primary_conninfo_password" ... If, for whatever reason, the upstream server password needs to be set in "primary_conninfo", enable it to be extracted from $PGPASSWORD.	2017-08-31 14:57:07 +09:00
Ian Barwick	ae634100a3	"standby switchover": sanity-check remote "repmgr" binary before proceeding	2017-08-31 11:00:14 +09:00
Ian Barwick	8e35a415a9	Refactor extraction of value to use for "primary_conninfo" ... Also add improved error detection. Basically in the worst case we want to enable the user to clone a standby from Barman even if the upstream node is not running/reachable, as long as the user explicitly provides a string to use for "primary_conninfo".	2017-08-31 09:59:30 +09:00
Ian Barwick	13f2d46e92	"standby clone": exit with 0 after successful --dry-run	2017-08-30 10:00:48 +09:00
Ian Barwick	8b03859dbe	"standby clone": add early sanity check for external configuration files ... This still requires an SSH connection, so we need to check early before the cloning starts, and also emit useful information for --dry-run.	2017-08-29 22:11:16 +09:00
Ian Barwick	b900f9996f	"repmgr standby clone": add --dry-run option	2017-08-28 15:04:50 +09:00

Ian Barwick	dc172cae20	When performing a follow operation, start/restart server as appropriate ... Before this we were always forcing a restart, which is technically not a problem but produces some potentially confusing log entries along the lines: pg_ctl: PID file "/path/to/postmaster.pid" does not exist Is server running? starting server anyway	2017-08-25 16:50:30 +09:00
Ian Barwick	a449e8512e	repmgr: improve "repmgr standby switchover" log output ... Particularly in --dry-run mode it's useful to get a confirmation that various prerequisites are met.	2017-08-25 16:01:11 +09:00
