Hi All,
We were trying to move a big database from one machine to the other using PITR mechanism. We hit the following LOG message in during the recovery (WAL replay) process"
LOG: incorrect resource manager data checksum in record at 111/A7738C8
I had used this procedure to do such migrations in the past, and never had any problem. This particular DB is pretty huge, and under load, so I would like to consider other options before even trying to redo the whole process.
Here's the whole scanario:
The DB is about 420 GB in size. We want to move it to another box with more storage. I have set up WAL archival, executed pg_start_backup(), started $DATA/ copy (took just over 24 hours), executed pg_stop_backup(), and while the WAL archival is still enabled I started recovery on the second machine, using the $DATA/ copied earlier....
I have the compressed WAL file, so if someone wishes to take a peek at it it will be available...
Considering this is a weekend, any help/suggestion at all would be great.
Thanks and best regards,
