This failure was caused because of several bugs: - Someone had removed s3-slave-ignore-updates=1 from slave.cnf, which caused the slave to remove files that the master was working on. - Bug in ha_partition::change_partitions() that didn't reset m_new_file in case of errors. This caused crashes in ha_maria::extra() as the maria handler was called on files that was already closed. - In ma_pagecache there was a bug that when one got a read error one a big block (s3 block), it left the flag PCBLOCK_BIG_READ on for the page which cased an assert when the page where flushed. - Flush all cached tables in case of ignored ALTER TABLE Note that when merging code from 10.3, that fixes the partition bug, use the code from this patch instead.
