mariadb: fix cluster recovery
sometimes cluster recovery didn't work because we only look for the sequence number in the last 200 lines of the log file. fix this by ingesting the complete file and only register the last sequence number we find. Closes-Bug: 1821173 Change-Id: Iea2661c9d5d262cf99edd5f5b567f252607a0003 Signed-off-by: Sven Kieske <kieske@osism.tech>

fixes:

|
||||
Fixed an issue where the MariaDB Cluster recovery process would fail if the
|
||||
sequence number was not found in the logs. The recovery process now checks
|
||||
the complete log file for the sequence number and recovers the cluster.
