Re: Table is marked as crashed and should be repaired after Aria recovery

Re: Table is marked as crashed and should be repaired after Aria recovery
This bug is still repeatable after the following fix:

message:
Fix for LP#634943 "marked as crashed", "zerofilling" and "wrong data in bitmap" when recovering Aria tables
This was an interaction of several bugs:

• Tables marked as opened was not properly unmarked on recovery if there was not changes since checkpoint
• zerofill of tables put wrong data in bitmap if directory for page was full
• Tables was thought as 'moved' during recovery if they had a create_lsn bigger than the lsn in the control file.

The .sql and the .yy file are available at hasky.askmonty.org:/home/philips/bug625739

A better RQG command line:

perl runall.pl \
--queries=1M \
--engine=Maria \
-mysqld=-safe-mode \
-mysqld=-sync-sys=0 \
-mysqld=-log-output=file \
-mysqld=-maria_log_purge_type=at_flush \

Re: Table is marked as crashed and should be repaired after Aria recovery
The reason for the auto-recovery is that you created the test tables as Myisam tables.
Fix: Add -mysqld=-default-storage-engine=maria as an option to RQG.

I tried running the test this way and verified that the problem didn't exits with Aria.
I did however notice two other problems while doing this.

• RQG didn't create the smf2 database before running maria_read_log, which causes maria_read_log to abort because it couldn't create the table files.
• Fixed by adding creation of missing databases to maria_read_log
• When reopening tables (can happen if table is reopened during checkpoint) file sizes was wrongly set from disk instead of from memory, which caused recovery to fail.

This is now fixed in 5.1 tree.

Re: [Bug 625739] Re: Table is marked as crashed and should be repairedafter Aria recovery
Yes, you are right, sorry about that. I have fixed the framework to always
add -mysqld=-default-storage-engine=Maria, which was the case before, but
was turned off for some reason.

The reason for the auto-recovery is that you created the test tables as
Myisam tables.
Fix: Add -mysqld=-default-storage-engine=maria as an option to RQG.

I tried running the test this way and verified that the problem didn't exits
with Aria.

Bug description:
When recovering from a DML scenario, the server reported the following:

1. 2010-08-28T12:13:14 100828 12:13:14 [ERROR] mysqld: Table
   './smf2/smf_log_online' is marked as crashed and should be repaired
2. 2010-08-28T12:13:14 100828 12:13:14 [Warning] Checking table:
   './smf2/smf_log_online'

Such automatic repair is only permissible when recovering from an ALTER
TABLE, which is not the case in this scenario.
