I am trying to setup a 2nd, identical, db server (M2) for development
and I've run into a problem with starting up the 2nd Postgres installation.
Here's what I've done:
1) did a 'clone' of 1st (production) machine M1 (so both machines on
Cent OS 7.2)
2) setup an rsync operation, did a complete 'rsync' from M1 to M2
3) did a final 'CHECKPOINT' command on M1 postgres
4) shutdown postgres on M1 with 'pg_ctl stop'
5) did final 'rsync' operation (then restarted postgres on M1 with
'pg_ctl start')
6) tried to startup postgres on M2
It won't start, & in the log file gives the error message:
...
< 2016-05-31 09:02:52.337 PDT >LOG: invalid primary checkpoint record
< 2016-05-31 09:02:52.337 PDT >LOG: invalid secondary checkpoint record
< 2016-05-31 09:02:52.337 PDT >PANIC: could not locate a valid
checkpoint record
< 2016-05-31 09:02:53.184 PDT >LOG: startup process (PID 26680) was
terminated by signal 6: Aborted
< 2016-05-31 09:02:53.184 PDT >LOG: aborting startup due to startup
process failure
I've tried several times to do this but always get this result. So, do
I need to do a new 'initdb..' operation on machine M2 + restore from M1
backups? Or is there another way to fix this?
