Обсуждение: [GENERAL] Cannot recover from backup on barman
Hello everyone,
I need to recover some partial data from a old backup.
The recover went smoothly up until the time to start the server, I cannot start the server.
LOG: invalid primary checkpoint record
LOG: invalid secondary checkpoint record
PANIC: could not locate a valid checkpoint record
LOG: startup process (PID 30975) was terminated by signal 6: Aborted
Well after some research, I was suggested to use the pg_resetxlog tool from postgres-xc, but people also advise against it.
Can anyone show me how to properly identify the problem with my backup? I am also worried that my backups are not being properly made.
Regards,
Alfredo Palhares

Hello Michael,
I don't understand why Postgres-XC is part of this discussion as
pg_resetxlog is part of PostgreSQL.
Well I did an apt-file search pg_resetxlog and this is what I found:
manpages-zh: /usr/share/man/zh_CN/man1/pg_
manpages-zh: /usr/share/man/zh_TW/man1/pg_
postgres-xc: /usr/bin/pg_resetxlog

postgresql-9.3: /usr/share/postgresql/9.3/man/
postgresql-9.3-dbg: /usr/lib/debug/usr/lib/
I did use barman recover to recover the directory.
The backup_label file is there, and these are the contents:
START WAL LOCATION: 1BE/7B0000A0 (file 00000001000001BE0000007B)
CHECKPOINT LOCATION: 1BE/7B6CB130
BACKUP METHOD: pg_start_backup
BACKUP FROM: master
START TIME: 2016-10-26 08:01:46 UTC
LABEL: Barman backup thingie 20161026T080002
Where should I look for said file to check if its there,

You may want to see that with the maintainers of barman, they are
likely looking at this list. But here is a guess: the backup_label
file has been removed.
