      Description

      While MDEV-28870 reduced the failure probability of test atomic.rename_table, the test still occasionally fails, especially on the kvm-ubsan builder. Here is the relevant part of one failure:

      10.6 0fa19fdebf0925be6ec5503938d541332f259cb5

      CURRENT_TEST: atomic.rename_table
      mysqltest: At line 155: query 'let $res=`select t1.a+t2.b+t3.c+t4.d from t1,t2,t3,t4`' failed: ER_UNKNOWN_STORAGE_ENGINE (1286): Unknown storage engine 'InnoDB'
      2022-06-22  8:00:48 0 [ERROR] InnoDB: Tablespace 5 was not found at ./test/t5.ibd.
      2022-06-22  8:00:48 0 [ERROR] InnoDB: Set innodb_force_recovery=1 to ignore this and to permanently lose all changes to the tablespace.
      2022-06-22  8:00:48 0 [ERROR] InnoDB: Plugin initialization aborted at srv0start.cc[1447] with error Tablespace not found
      

      I would need at least a copy of a data directory that failed to recover. Preferrably from 10.8 or a later branch, because the MDEV-14425 log file format is easier to read, thanks to the lack of any block framing. An rr record trace of the killed server could significantly ease the analysis.
