GALLIANO Nicolas

Hi,

 

I’m trying to backup a remote DB (9.6.6) using barman 2.3 but backup failed start.

In barman.log i’ve such errors :

RE: Barman 2.3 errors

In reply to this post by GALLIANO Nicolas

 

Hi Nicolas,

 

I would like to take stab at this one, as i had recently worked on a demo of barman. But like Michael Paquier said, it is better to check the information i provide and the situation you are facing with the maintainers of the project. Here is what i found.

 

The first thing is to check if you can see the replication slot named "barman" created on the target database using the below command. It should return a slot named "barman" with the slot_type as "physical". The "replication slot: OK" line of the check command shows the slot is available, however, please double check if it is true with the below query.

 

 

select * from pg_replication_slots;

 

 

Now let us target the line "WAL archive: FAILED", I faced this issue when i had killed the "receive-wal" process and restarted it.  First look for the receive-wal process with the ps command

 

ps -ef|grep receive-wal

 

if it is not running then start it up in the background using the command

 

$ barman receive-wal tcgepg96ddm &

 

If the receive-wal process is running but you still face that error in the check command, then I suggest you switch the xlog using the below command.

 

$ barman switch-xlog tcgepg96ddm

 

if the above command fails to switch the xlog, then try to force it with the below command.

 

$ barman switch-xlog --force tcgepg96ddm

 

if you still cannot get it to work, then try to reset the status of the receive-wal process using the --reset option as below.

 

$ barman receive-wal --reset tcgepg96ddm

 

 

If you can successfully run the above reset command, then try to switch the log file  and run the check command again to see if everything looks fine.

 

$ barman switch-xlog tcgepg96ddm

 

 

Hope that helps, again, these are the steps i had taken to resolve a similar issue. You might still want to get in touch with the project maintainers about the validity of the above commands.

 

 

Best Regards,

RE: Barman 2.3 errors

GALLIANO Nicolas

Hi

 

1/ thanks for your answer

2/ it’ right … the barman support list is better … sorry

3/ i’ve verified the pg replication slot :

 

postgres@postgres# SELECT slot_name, active, restart_lsn FROM pg_replication_slots WHERE slot_type = 'physical' AND slot_name = 'barman';

slot_name | active | restart_lsn

-----------+--------+-------------

barman    | t      | 1/7B000840

 

 

4/ i’ve tried this :

 

-          Receive-wal process not running :

barman@tcgipocgresql:/var/log/barman [2018/02/13-09:23:53]

$ps -ef |grep receive-wal

barman   48067  4398  0 09:58 pts/0    00:00:00 grep --color=auto receive-wal

 

-          Receive-wal process failed start :

$barman receive-wal tcgepg96ddm

Starting receive-wal for server tcgepg96ddm

ERROR: ArchiverFailure:replication slot 'barman' is already in use

 

-          Receive-wal reset :

$barman receive-wal --reset tcgepg96ddm

Starting receive-wal for server tcgepg96ddm

Resetting receive-wal directory status

Removing status file /var/lib/barman/tcgepg96ddm/streaming/00000001000000010000007B.partial

 

-          Switch-xlog :

$barman switch-xlog tcgepg96ddm

The WAL file 00000001000000010000007B has been closed on server 'tcgepg96ddm'

 

Then if i try when the replication slot is not active the receive-wal crash and i have this error :

 

$barman receive-wal tcgepg96ddm

Starting receive-wal for server tcgepg96ddm

EXCEPTION: 'utf8' codec can't decode byte 0xe0 in position 47: invalid continuation byte

See log file for more details.

 

And in the log i still have the UnicodeDecodeError …

 

On a post (https://sourceforge.net/p/pgbarman/tickets/88/)  i’ve found that it’s a barman bug with a workaround … but the solution don’t work for me ...

I’m still looking for a solution L

 

Thanks for your help

Have a good day

nicolas

$barman switch-xlog tcgepg96ddm

The WAL file 00000001000000010000007B has been closed on server 'tcgepg96ddm'

 

Then if i try when the replication slot is not active the receive-wal crash and i have this error :

 

$barman receive-wal tcgepg96ddm

Starting receive-wal for server tcgepg96ddm

EXCEPTION: 'utf8' codec can't decode byte 0xe0 in position 47: invalid continuation byte

See log file for more details.

 

And in the log i still have the UnicodeDecodeError …

 

On a post (https://sourceforge.net/p/pgbarman/tickets/88/)  i’ve found that it’s a barman bug with a workaround … but the solution don’t work for me ...

I’m still looking for a solution L

 

Thanks for your help

Have a good day

Hi Nicolas,

 

I would like to take stab at this one, as i had recently worked on a demo of barman. But like Michael Paquier said, it is better to check the information i provide and the situation you are facing with the maintainers of the project. Here is what i found.

 

The first thing is to check if you can see the replication slot named "barman" created on the target database using the below command. It should return a slot named "barman" with the slot_type as "physical". The "replication slot: OK" line of the check command shows the slot is available, however, please double check if it is true with the below query.

 

 

select * from pg_replication_slots;

 

 

Now let us target the line "WAL archive: FAILED", I faced this issue when i had killed the "receive-wal" process and restarted it.  First look for the receive-wal process with the ps command

 

ps -ef|grep receive-wal

 

if it is not running then start it up in the background using the command

 

$ barman receive-wal tcgepg96ddm &

 

If the receive-wal process is running but you still face that error in the check command, then I suggest you switch the xlog using the below command.

 

$ barman switch-xlog tcgepg96ddm

 

if the above command fails to switch the xlog, then try to force it with the below command.

 

$ barman switch-xlog --force tcgepg96ddm

 

if you still cannot get it to work, then try to reset the status of the receive-wal process using the --reset option as below.

 

$ barman receive-wal --reset tcgepg96ddm

 

 

If you can successfully run the above reset command, then try to switch the log file  and run the check command again to see if everything looks fine.

 

$ barman switch-xlog tcgepg96ddm

 

 

Hope that helps, again, these are the steps i had taken to resolve a similar issue. You might still want to get in touch with the project maintainers about the validity of the above commands.

 

 

Best Regards,
