Failing process: Install mariadb from ppa using apt (happens through salt, fwiw) Download last night's backup from a 10.6.4 server, which is a replica from a galera cluster. run the script attached restore_mariabackup.sh Once this is done the database itself works, for our application, but any client trying to access anything that requires mysql.proc gets an error similar to: *Sep 30 19:29:07 devmaria /etc/mysql/debian-start[24656]: error : CorruptSep 30 19:29:07 devmaria /etc/mysql/debian-start[24656]: sys.x$schema_table_statistics* *Sep 30 19:29:07 devmaria /etc/mysql/debian-start[24656]: Error : Cannot load from mysql.proc. The table is probably corrupted * I just built two new servers, one that builds mariadb and then overwrites the data from a backup and one that just installs mariadb. The two different files base_install.proc.sql and backupedup.proc.sql. The error output from sudo mysql_upgrade on the server that received the backup is in mysql_upgrade.out There are more differences in the proc table if i dump the data as well, but i think much of it is driven by the utf8_mb4 rather than 3. Tried to keep this sucient and use attachments. This process has worked for me for until i upgraded to 10.6.4. Please ask anything you need. I think i've been using this similar process to build dev machines since about 10.4 Thanks Jeff
