Changes in v1.6.1

Maintenance Release: July 4th, 2018

  • Build:
    • clustercontrol-1.6.1-4896
  • UI:
    • Identical host charts fix for SQL and Data Nodes with MySQL Cluster (NDB).
    • ‘DB User Management’ fix with MySQL Cluster (NDB). Create and edit DB users works again.

Maintenance Release: June 28th, 2018

  • Build:
    • clustercontrol-controller-1.6.1-2621
  • Controller:
    • MariaDB: Deployment fix caused by a mix up of authentication_string and password in the mysql.user table.
    • Restore slaves/Rebuild nodes (MySQL, PostgreSQL) – Making the directory of the datadir backup configurable. Specify datadir_backup_path in /etc/cmon.d/cmon_X.cnf. By default, the datadir will be copied (after the server has been shut down, but before restoring/rebuilding) using a filesystem copy to {datadir}_bak.
    • Error reporting: A fix to also include the include files of a database node configuration file.
    • Alarms: Fixed an issue when the measured value was a NaN or INF.
      MySQL: Add Node could fail due to a bug in version detection.
    • General: A fix allowing other jobs to run in parallel with remove cluster jobs.

Maintenance Release: June 26th, 2018

    • Fix missing validation for the xtrabackup --use-memory option.
    • Add ‘Lock DDL per table’ option for xtrabackup.
    • Fixes to cmon-events to handle filtering correctly.

    • PostgreSQL: show error log when node failed to start.

    • Galera: Fixed a crashing bug in case of missing wsrep_sst_auth.
    • Maxscale: Fixed so that the software will not be installed if it is already installed on the node.

Feature Details

  • Backup:
    • Support for MariaDB Backup for MariaDB based clusters. MariaDB Server 10.1 introduced MariaDB Compression and Data-at-Rest Encryption which is supported by MariaDB Backup (a fork of Percona XtraBackup).
    • Support for Schema(--no-data) or Data(--no-create-info) only backups and skipping extended insert(--skip-extended-insert) with mysqldump.
    • Support for --use-memory with xtrabackup.
    • Support for custom backup subdirectory names:

Set the name of the backup subdirectory. This string may hold standard %X field separators, the %06I for example will be replaced by the numerical ID of the backup in 6 field-wide format that uses ‘0’ as leading fill characters. Default value: BACKUP-%I.

Variable Description
B The date and time when the backup creation was beginning.
H The name of the backup host, the host that created the backup.
i The numerical ID of the cluster.
I The numerical ID of the backup.
J The numerical ID of the job that created the backup.
M The backup method (e.g. mysqldump).
O The name of the user who initiated the backup job.
S The name of the storage host, the host that stores the backup files.
% The percent sign itself. Use two percent signs, <span class="pre">%%</span> the same way the standard <span class="pre">printf()</span> function interprets it as one percent sign.
  •  PostgreSQL:
    • Synchronous Replication Slaves.
    • Multiple NICs support:

Deploy DB nodes using management/public IPs for monitoring connections and data/private IPs for replication traffic.
Deploy HAProxy using management/public IPs and private IPs for configurations.

  • Misc:
    • ServiceNow has been added as a new notifications integration.
    • Support for MaxScale 2.2.
    • Database User Management (MySQL) can now search/filter accounts on username, hostname, schema or table.
    • Node page graphs are now showing accurate time ranges and datapoint gaps.
    • Query Monitoring is using the CMON RPC API.
    • Database Growth is using the CMON RPC API.
