Hello,
First of all thank you for this awesome tool. I am trying to use it correctly
since 2 days and I am taking a lot of fun :)
I am on debian 7, bucardo 4.99.7 get from source, postgresql 9.1.9 from a
official stable package.
So after few hundreds tabs, here I am :)
After the install and the setup, I have tried to play a little bit with this
tool before using it for my company in production across the atlantic. And at a
time, from "Good" state it switched to "Bad" State. And i really don't know
what to do with it.
FYI Bucardo is installed on the same host than FR_BDD.
My configuration :
~ % bucardo list dbs
~
Database: LA_BDD Status: active Conn: psql -p -U bucardo -d mybdd -h IP_LA
Database: FR_BDD Status: active Conn: psql -p -U bucardo -d mybdd -h IP_FR
~ % bucardo list dbgroup
Database group: BDD_GROUP Members: LA_BDD:source FR_BDD:source
~ % bucardo list tables | head
630. Table: public.admin_right DB: LA_BDD PK: id_admin_right
(int4) Syncs: BDD_SYNC
639. Table: public.admin_user DB: LA_BDD PK: id_admin_user
(int4) Syncs:BDD_SYNC
631. Table: public.alias DB: LA_BDD PK: alias_id (int4)
Syncs: BDD_SYNC
[...]
~ % bucardo list sequences | head
Sequence: public.admin_right_id_admin_right_seq DB: LA_BDD
Sequence: public.admin_user_id_admin_user_seq DB: LA_BDD
Sequence: public.alias_alias_id_seq DB: LA_BDD
[…]
~ % bucardo list herds
Relgroup: BDD_HERD1 DB: LA_BDD Members: public.admin_right,
public.admin_user, […]
Used in syncs: BDD_SYNC
~ % bucardo list syncs
Sync: BDD_SYNC Relgroup: BDD_HERD1 [Active]
DB group BDD_GROUP: LA_BDD (source) FR_BDD (source)
I have few questions :
1/ So i have now a "Bad" State and i really don't know what to do with it.
I have tried a :
bucardo reload sync MY_BDD_SYNC ( what are the exact meaning of this command
by the way ? )
bucardo validate ( what are the exact meaning of this command by the way ? )
bucartdo stop / start
Without knowing what i was really doing… and this didn't change anything to my
problem. I have looked for some informations a little bit everywhere on the
internet but without success.
FYI all the tables have just fews columns, without data. I played with just few
INSERT.
~ % bucardo status
Name State Last good Time Last I/D Last
bad Time
========================+========+============+============+===========+===========+============
BDD_SYNC | Bad | 02:27:38 | 7h 58m 46s | 0/1 | 02:51:12 | 7h 35m
13s
What can I do in such situations ?
Maybe there is a http link somewhere that I missed ?
2 / When i added my tables:
~ % bucardo add all tables herd=BDD_HERD1 db=LA_BDD
I choose to add the tables which are on the distant host (THERE). Why not
choosing the tables which are on the same host (HERE, the one which have
bucardo installed on ) ?
I do have to choose only tables from one pgsql server right ? not from both
like : bucardo add all tables herd=BDD_HERD1 db=LA_BDD && bucardo add all
tables herd=BDD_HERD1 db=FR_BDD ?
3/ I launch the process bucardo with a bucardo system user, which is not root.
I have changed the rights of /var/run/bucardo and /var/log/bucardo. Is that ok
for you ? I do not see any errors in normal logging mode.
4/ Is there a way to remove all tables from a database without destroying the
database ?
If I want to remove all tables I currently do :
~ % bucardo remove database LA_BDD --force
5 / When i add a sync :
bucardo add sync BDD_SYNC herd=BDD_HERD1 dbs=BDD_GROUP ping=false autokick=1
Why choosing ping=false ?
6 / When i try to update a config :
For exemple :
~ % bucardo update sync BDD_SYNC autokick=0
Then i do a :
~ % bucardo reload config ~
Forcing Bucardo to reload the bucardo_config table
and I have this warning/error message :
Waited, but Bucardo never confirmed the configuration reload!
zsh: exit 11 bucardo reload config
7/ Wnen i try a "bucardo show all", i have got an exit 1 at the end. Is it ok?
~ % bucardo show all
