About PiHome and Its Evolution

@twa127 updated my dev. system and database migrated all good.

[pihome-shc]

@twa127 when i setup new database it still requires migrate_controller.php, can these changes added to database for new setup so user don't need to run migrate_controller.php

[twa127]

I left the database changes out because it caused problems when we did the sensor split migration. I thought leave it for a couple of days for most people to implement, then put in the database and view changes,

Hi, Upgraded from 1.75 and had the following errors:

Applying Updates to Database.
MySQL Database Error with Query ALTER TABLE zone DROP sensor_id;
:Cannot drop index 'FK_zone_nodes': needed in a foreign key constraint
MySQL Database Error with Query ALTER TABLE zone MODIFY CONSTRAINT FK_zone_type_id FOREIGN KEY (type_id) REFERENCES zone_type (id);
:You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'CONSTRAINT FK_zone_type_id FOREIGN KEY (type_id) REFERENCES zone_type (...' at line 1
MySQL Database Error with Query ALTER TABLE zone DROP INDEX FK_zone_nodes;
:Cannot drop index 'FK_zone_nodes': needed in a foreign key constraint

Additionally seem to have lost all my nodes and previous config.

[twa127]

Hi,

I guess you probably had the same issue as @scottagecheeseandcrackers, I would suggest going back to a copy of the database before the update, then -

1. run migrate_db.php
2. run migrate_controller.php

DO NOT run update_db.php at any point

[baseline-s]

Thanks, that solved the zone issues. load average is exceptionally high now with mysql taking most of the cpu. I'll have to dig deeper to understand why this is so. Running this on an old ModelB.

[twa127]

yeah the load has crept up over the last few releases
