Marko Mäkelä added a comment - 2017-09-15 11:31 Why Mariabackup 10.2 is not affected The 10.2 version of Mariabackup never processed any transactions, that is, the --apply-log-only is the default parameter. MDEV-13466 for Mariabackup 10.2.9 introduced the --export option, which will start up and shut down the normal server, and will perform the rollback. The bug and fix in Mariabackup 10.1 Percona Xtrabackup 2.3 uses the variable srv_apply_log_only. But, the Mariabackup 10.1 implementation in MDEV-9566 is missing necessary references to this variable in the files srv0start.cc, log0recv.cc, trx0rseg.cc. There are references in srv0srv.h, srv0srv.cc, trx0sys.cc. All these references must correspond to what xtrabackup is doing. To ensure that further bugs in this class will not go undetected, I think that the following additional code is needed in srv0start.cc, in the appropriate place of innobase_start_or_create_for_mysql(): ut_d(recv_no_log_write = srv_apply_log_only); Last but not least, MDEV-11985 introduced an assertion to trx_free_prepared() that would fail on mariabackup --prepare if any recovered transactions exist. I fixed this in 10.2.9 after seeing the failure on buildbot. This assertion relaxation must be backported to 10.1. The assertion would not fail in the 10.1 mariabackup --prepare because because of this bug, it would always roll back all recovered transactions.

OK   To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system   PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER ! To do so, start the server, then issue the following commands:   '/home/a/mariadb-environs/m3-10.1.26/../_depot/m-tar/10.1.26/bin/mysqladmin' -u root password 'new-password' '/home/a/mariadb-environs/m3-10.1.26/../_depot/m-tar/10.1.26/bin/mysqladmin' -u root -h UBINTI password 'new-password'   Alternatively you can run: '/home/a/mariadb-environs/m3-10.1.26/../_depot/m-tar/10.1.26/bin/mysql_secure_installation'   which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers.   See the MariaDB Knowledgebase at http://mariadb.com/kb or the MySQL manual for more instructions.   You can start the MariaDB daemon with: cd '/home/a/mariadb-environs/m3-10.1.26/../_depot/m-tar/10.1.26' ; /home/a/mariadb-environs/m3-10.1.26/../_depot/m-tar/10.1.26/bin/mysqld_safe --datadir='/dev/shm/__var0/var1/data'   You can test the MariaDB daemon with mysql-test-run.pl cd '/home/a/mariadb-environs/m3-10.1.26/../_depot/m-tar/10.1.26/mysql-test' ; perl mysql-test-run.pl   Please report any problems at http://mariadb.org/jira   The latest information about MariaDB is available at http://mariadb.org/.
