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.

Ian Barwick 5b5b456ecb "standby switchover": improve logging
Also no need to disconnect/reconnect from/to local node while it promotes.

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.

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.

Ian Barwick 72e037d55b SCRIPTS_built also required for 9.4 2017-09-02 12:03:17 +09:00
Ian Barwick 4ba3e67e11 Hacky workaround for hacky workaround in 9.4
For some reason 9.4 doesn't install the repmgr/repmgrd binaries
with "SCRIPTS_built". "SCRIPTS" seems to work for both 9.4 and
later versions.

Ian Barwick 705b52fde4 Use actual program name rather than "repmgr" when executing remote commands
It's possible some distribution packages may assign a different name to the
"repmgr" binary (typically appending a version number), so we shouldn't hard-code
into the command string.

However it's reasonable to assume the "repmgr" binary will have the same name
across a replication cluster so we won't engage in any contortions to account
for possible variations.

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".

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.
