Description

Customer is running backup on very large dataset (18TB). Backup completes successfully, but fails during prepare step.
Here is the planned backup process as the customer has detailed:

1. On Source:
  mariabackup --user=root --backup --target-dir=/opt/database/backup --stream=xbstream --parallel=12 | pigz -c | socat - TCP-LISTEN:4444,reuseaddr
2. On Target
  rm -rf /var/lib/mysql/*
  rm -rf /var/log/mysql/*
  cd /var/lib/mysql
  socat -u TCP:192.168.111.184:4444 STDOUT | pigz -dc | mbstream -x
  mariabackup --user=root --use-memory=100G --prepare --target-dir=/var/lib/mysql/
  rm -rf ib_logfile*
  chown -R mysql:mysql /var/lib/mysql/
  systemctl start mariadb

The prepare fails as such:
2020-11-03 15:08:46 0 [Note] InnoDB: To recover: 2407553 pages from log
2020-11-03 15:08:54 0 [ERROR] InnoDB: Not applying INSERT_REUSE_REDUNDANT due to corruption on [page id: space=0, page number=120831]

I am also having a similar issue.

I have two servers in an active-active replication configuration running 5.6. They had been online for about 45 days. Replication hung and I was unable to stop replication or shutdown the server. I ended up killing the process and on restart, the recovery failed with these same errors. This was not critical data for us so I decided I would re-sync from the master. I removed the dataset and prepared a backup with MariaDB Backup. To my surprise, when I tried to prepare the backup, I ran into the same issues after the crash. There seems to be something 5.6+ feels is corrupted with these datasets. I also upgraded to 5.8 on the restoration server, however the backup server is still 5.6.

My dataset is small compared to the OP, only 377GB.

This issue relates to TODO-2645 [ TODO-2645 ]

Vladislav Lesin added a comment - 2020-11-18 13:15 - edited

The error itself is issued from page_apply_insert_redundant(), which is called after page corruption check. So the page is not corrupted as it passed the check, that is why backup was finished successfully. According to the page_apply_insert_redundant() there can be several reasons of the error, so I modified this function to determine what exactly reason caused the error message, and created custom build request: TODO-2645. Please ask the customer to run "mariabackup --prepare" with "--dbug=d,ib_log" option, and then send mariabackup log to us.

This issue relates to ~~MDEV-18976~~ [ ~~MDEV-18976~~ ]

Marko Mäkelä added a comment - 2020-11-19 05:45

I believe that the cause of this is that the write-ahead logging constraints were broken at some point of the chain. In ~~MDEV-17289~~ we had something very similar to this. The way how inserts of records into index pages are logged and applied was rewritten in ~~MDEV-21724~~. It is possible that the more thorough consistency checks that were implemented in ~~MDEV-21724~~ allow to catch such corruption in a few more cases. Before that rewrite, we might allow recovery to proceed and might hit a hard-to-reproduce problem later.

I believe that implementing ~~MDEV-18976~~ would make recovery more robust, by allowing even better consistency checks. If that measure is implemented, recovery should be able to notice that a page image is not in sync with the log record, or that some log record was missed during recovery.

Note: The move to more physical redo log format in ~~MDEV-12353~~ removed some opportunity to perform consistency checks. But, even with the old implementation, I think that by far, the best chances to notice such inconsistency was when trying to apply an insert operation. The inconsistency typically led to the server crashing (repeatedly). With the new ~~MDEV-12353~~/~~MDEV-21724~~ log format, we are reporting an error and avoiding a crash. (OK, until ~~MDEV-13542~~ is fixed, we may crash when the corrupted table is accessed.)

Marko Mäkelä added a comment - 2020-11-19 05:45 I believe that the cause of this is that the write-ahead logging constraints were broken at some point of the chain. In MDEV-17289 we had something very similar to this. The way how inserts of records into index pages are logged and applied was rewritten in MDEV-21724 . It is possible that the more thorough consistency checks that were implemented in MDEV-21724 allow to catch such corruption in a few more cases. Before that rewrite, we might allow recovery to proceed and might hit a hard-to-reproduce problem later. I believe that implementing MDEV-18976 would make recovery more robust, by allowing even better consistency checks. If that measure is implemented, recovery should be able to notice that a page image is not in sync with the log record, or that some log record was missed during recovery. Note: The move to more physical redo log format in MDEV-12353 removed some opportunity to perform consistency checks. But, even with the old implementation, I think that by far, the best chances to notice such inconsistency was when trying to apply an insert operation. The inconsistency typically led to the server crashing (repeatedly). With the new MDEV-12353 / MDEV-21724 log format, we are reporting an error and avoiding a crash. (OK, until MDEV-13542 is fixed, we may crash when the corrupted table is accessed.)

The customer's consultant has tried preparing again using the debug build. Output is attached to case CS0154009. There's a bit more information about the generic error.

I have hit the same error on 10.5.8

The option "Set innodb_force_recovery=1 to ignore corruption." sounds risky.

Can anyone suggest a workaround?

Thanks

For 10.5, this could have been fixed by ~~MDEV-25031~~, which fixed a regression that was introduced in 10.5.
For 10.2.27, I have no idea of the cause.

Pull request #1772 would implement innodb_force_recovery=1 for mariabackup --prepare, and I think solve this issue.

The contributed fix is basically only a work-around: it allows the option --innodb-force-recovery=1 to be specified when applying logs (preparing a backup).

The root cause of the failure is always something else (such as ~~MDEV-25031~~ for the case that is in the Description). This work-around allows an attempt to restore a backup even if some corruption is present.

marko will the backup still be consistent when restoring with force-recovery=1? especially regarding the position resp. the master (in case we want to make this server a replica)?

The purpose of innodb_force_recovery=1 is to ignore some errors (corrupted pages or missing data files). Depending on where the errors occur, it may or may not be safe. In the general case, I would not recommend to continue using a server where recovery errors had been ignored in the past.

When it comes to MariaDB Server (not Mariabackup), it would be nice if there was a way to set innodb_force_recovery to the values 2 or 3 in such a way that the recovery will run in strict mode. If no crash recovery is involved, those values of the parameter are not expected to cause further corruption. The main purpose of innodb_force_recovery is to allow data to be extracted from a corrupted database.
