Comment by Marko Mäkelä [ 2020-07-23 ]

I think that the fatal error message is worth mentioning. Quoting the buildbot log:

10.2 6898eae7f8ef3f0b773687c0308520f072da0bc9

 
2020-07-22  6:20:40 140227487697216 [ERROR] [FATAL] InnoDB: Trying to read page number 4278108161 in space 0, space name innodb_system, which is outside the tablespace bounds. Byte offset 0, len 16384Please check that the configuration matches the InnoDB system tablespace location (ibdata files)

The value 4278108161 is 0xFEFEC001.

thiru reported that when he repeated this failure locally by repeatedly running something like

./mtr --parallel=auto --mysqld=--debug=d,ib_log_checkpoint_avoid --repeat=100 encryption.innodb-encryption-alter,cbc,innodb{,,,}

he found a request for the invalid page number 4278124286 (0xFEFEFEFE) which prompted a read request for the corresponding change buffer bitmap page 0xFEFEC001.

The value 0xfe is being written to buf_block_t::frame in the function buf_LRU_block_free_non_file_page(), but ít is not established yet whether there is any connection to that.

Comment by Matthias Leich [ 2020-07-24 ] 

MDEV-23260B.test   is a simplified version of the original test.
 
 
 
I made several hundred attempts to replay the problem when the tool "rr" is invoked.
 
while ./mtr --parallel=`nproc` --vardir=/dev/shm/omo --rr --rr-arg="-h" --mysqld="--debug_dbug=d,ib_log_checkpoint_avoid" --mysqld=--innodb_log_files_in_group=1 --mysqld=--innodb_log_buffer_size=1048576 --mysqld=--innodb_log_file_size=2097152 encryption.MDEV-23260B{,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,}; do :; done
 
None of these tests replayed the problem.
 
 
 
When omitting "rr"
 
while ./mtr --parallel=`nproc` --vardir=/dev/shm/omo  --mysqld="--debug_dbug=d,ib_log_checkpoint_avoid" --mysqld=--innodb_log_files_in_group=1 --mysqld=--innodb_log_buffer_size=1048576 --mysqld=--innodb_log_file_size=2097152 encryption.MDEV-23260B{,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,}; do :; done
 
a replay comes quite fast.
 
 
 
I am giving up with replay attempts using "rr".

I got this failure again on 10.2 with some cleanup and a fix of MDEV-16115:

2020-08-10 14:44:46 140695089317824 [ERROR] [FATAL] InnoDB: Trying to read page number 4278108161 in space 0, space name innodb_system, which is outside the tablespace bounds. Byte offset 0, len 16384Please check that the configuration matches the InnoDB system tablespace location (ibdata files)

mleich, could you try the following variation of the test:

  1. Kill the server just like we used to do it.
  2. Before the attempt to restart the server, back up the data directory.
  3. Start up the server.
  4. If the recovery failed in this way, attach the backed-up data directory.

Once we have a copy of a data directory where the recovery may fail, I believe that it should be possible to repeat the recovery failure under rr replay. I think that the error is something that happens during recovery, and does not necessarily depend on any error that occurred before the server was killed.

Comment by Thirunarayanan Balathandayuthapani [ 2020-08-31 ]

I added the assert in mtr_t::finish_write to check whether page no > 10000 to crash. (I put 10000 as kind of big number)
