Thanks for catching that. Typo on my end. Now I am getting this. Performing Consistency Checks on Old Live Server ------------------------------------------------ Checking cluster versions ok old and new pg_controldata WAL segment sizes are invalid or do not match Failure, exiting I found the setting in the current version of the instance via "show all" as "wal_segment_size | 16MB". I guess my new instance should be "16MB" as well when running this "initdb --wal-segsize=16 -D /hostname/pg/NewInstance/data"?
Well the default is 16MB so you should not have to set it. What does: pg_controldata -D <11.5 data dir> pg_controldata -D <12.1 data dir> show for the setting Bytes per WAL segment: ? -- Adrian Klaver adrian.klaver@xxxxxxxxxxx
