Dump the databases and recreate them with --data-checksums and Btrfs No_COW attribute. You can add this to /etc/postgresql-common/createcluster.conf in Debian/Ubuntu if you use pg_createcluster: initdb_options = '--data-checksums' -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
