See the example I posted on 10/14/21 12:45 PM, If the output is too noisy, use the zfs list -t filesystem option. As for path differences, use Perl, etc., to neutralize the expected -- e.g. data/home on the source and data/backup/home on the destination: # zfs get -r all data | perl -pe 's/data\/home/FOO/' > src.out # ssh remote.system zfs get -r all data | perl -pe 's/data\/backup\/home/FOO/' > dst.out Use use diff --ignore-all-blanks to ignore whitespace changes. Look at the output for more expected changes and/or things you do not care about. Keep adding stages until all expected changes are eliminated. Either you will end up with nothing or with unexpected changes -- which might the cause of the warning. >> Same as above for the pool properties. >> >> Have you tried replicating from the receiver? > > not been able to do these two yet due to time constraints > >> Have you tried reproducing the issue with a 13.0-RELEASE sender and/or >> receiver? > > not with 13.0-RELEASE.
