Re: [Maria-discuss] Horrendeous InnoDB crash

No, honestly, that wasn't it. :) As per the Jira link Jan Lindström provided, the data becomes corrupted as a result of certain queries! (I didn't know why, but it was pretty repeatable: wipe the database, re-populate it again, run the scheduled script, and bam, the 'xovers' table immediately crashes). Without the fix provided in 10.1.14, I would have never been able to solve this (except maybe to revert to myisam). A big thanks again to Jan Lindström, for identifying the issue, and to everyone else willing to think along with me! :) -----Original Message----- From: Jan Steinman [mailto:Jan@EcoReality.org] Sent: Tuesday, June 7, 2016 01:05 To: Mark <asarian(a)xs4all.nl> Cc: chris(a)mariadb.com; maria-discuss(a)lists.launchpad.net Subject: Re: [Maria-discuss] Horrendeous InnoDB crash > So, with almost certainty, the scheduled task corrupts the database.

[Maria-discuss] Horrendeous InnoDB crash
by Mark 07 Jun '16

07 Jun '16

Got a huge crash today, right after initializing my first MariaDB database (see below). Got several more errors about tables having crashed later on, and MariaDB wouldn't even start up any more (I wound up wiping the entire database). So, my question is, what could cause MariaDB to fail so horrendeously?! I though InnoDB was supposed to be *better* than myisam!? Is is because maybe Windows 10 doesn't give MariaDB enough time to shut down gracefully? Could it be because a Windows scheduler job (potentially) aborts the fetcher script when it's still running? (Again, I though InnoDB was supposed to be transaction-safe). In its current state, MariaDB is completely unusable for me. And no, I don't have hard disk errors. :) Seriously, though, I could use some major insight!

The log starts just with: 2016-06-06 16:39:16 7716 [Note] Server socket created on IP: '::'. 2016-06-06 16:39:16 7716 [Note] C:\xampp\mysql\bin\mysqld.exe: ready for connections. Version: '10.1.13-MariaDB' socket: '' port: 3306 mariadb.org binary distribution No errors at startup (database prefilled with manually run retrieval script). Then, at 16:47, when the scheduled retrieve task starts for the first time, the log adds: InnoDB: Error: trying to access page number 250370 in space 69, InnoDB: space name news/commentsxover, InnoDB: which is outside the tablespace bounds. InnoDB: Byte offset 0, len 16384, i/o type 10. InnoDB: If you get this error at mysqld startup, please check that InnoDB: your my.cnf matches the ibdata files that you have in the InnoDB: MySQL server. 2016-06-06 16:47:38 a74 InnoDB: Assertion failure in thread 2676 in file fil0fil.cc line 5866 So, with almost certainty, the scheduled task corrupts the database. Especially since I was now (unfortunately) able to replicate the same conditions for the crash. But there's nothing in that php script that could normally do that. (Especially since it runs manually just fine, without corrupting anything). The scheduled task runs as me, but is 'hidden', though (i.e., doesn't open a console). -----Original Message----- From: Chris Calender [mailto:chris.calender@mariadb.com] Sent: Monday, June 6, 2016 17:44 To: Mark <asarian(a)xs4all.nl>; maria-discuss(a)lists.launchpad.net Subject: Re: [Maria-discuss] Horrendeous InnoDB crash Hello, No need for the config file, you have corruption in your tablespace, hence the crash.

Then, about 8 minutes later, you attempt to select from the same table that is corrupted ("spotweb.commentsxover"), hence the immediate assertion failure: > 2016-06-06 16:47:38 a74 InnoDB: Assertion failure in thread 2676 in > file fil0fil.cc line 5866 And the stack trace confirms the query: > Query (0x4b01740): SELECT messageid FROM commentsxover ORDER BY id DESC > LIMIT 5000 Since that is the only table referenced as being corrupted, you could probably get by with dropping it and then restoring it from a backup. If you do not have a current backup, then you will need to enable innodb_force_recovery (read below link for details), then dump from the table, dumping "around" the corruption using mysqldump with ORDER BY pk and LIMIT, and then once you have as much data as possible, then DROP the table, and import your dump. http://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html Hope this helps!

Re: [Maria-discuss] Horrendeous InnoDB crash

InnoDB is different from MyISAM. It crashed intentionally, as stated in the log you posted, to avoid data corruption propagation.

[Maria-discuss] Galera Cluster on FreeBSD
by Niklaas Baudet von Gersdorff 03 Jun '16

03 Jun '16

Hello, I'm trying to setup a galera cluster on FreeBSD. I followed the instructions on [1] but every time I issue SHOW STATUS LIKE 'wsrep_cluster_size'; I get +--------------------+-------+ | Variable_name | Value | +--------------------+-------+ | wsrep_cluster_size | 0 | +--------------------+-------+ 1 row in set (0.00 sec) So, the cluster is not working. This is the configuration of the node that I want to set as primary: -----------------------------------8<----------------------------------- [mysqld] datadir=/var/db/mysql socket=/tmp/mysql.sock user=mysql binlog_format=ROW bind-address=0.0.0.0 default_storage_engine=innodb innodb_autoinc_lock_mode=2 innodb_flush_log_at_trx_commit=0 innodb_buffer_pool_size=122M wsrep_provider=/usr/local/lib/libgalera_smm.so wsrep_provider_options="gcache.size=300M; gcache.page_size=300M" wsrep_cluster_name="klaas_cluster" wsrep_cluster_address="gcomm://" #wsrep_cluster_address="gcomm://10.1.7.1,10.1.7.2,10.3.7.1" wsrep_sst_method=rsync [mysql] wsrep_cluster_name=klaas_cluster wsrep_cluster_address="gcomm://10.1.7.1,10.1.7.2,10.3.7.1" wsrep_node_name=box-hlm-01 wsrep_node_address="10.1.7.1" [mysql_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid ----------------------------------->8----------------------------------- On the other two nodes the configuration is the same, except (1) only the second `wsrep_cluster_address` exists; (2) `wsrep_node_address` differs, obviously. Instead of using an "empty" `wsrep_cluster_address` I also tried setting mysql_args="--wsrep-new-cluster" in /etc/rc.conf without getting the desired result. The logs lack any relevant warnings or errors: -----------------------------------8<----------------------------------- 160602 07:59:44 mysqld_safe mysqld from pid file /var/db/mysql/mariadb1.box-hlm-01.klaas.pid ended 160602 08:00:34 mysqld_safe Starting mysqld daemon with databases from /var/db/mysql 2016-06-02 8:00:34 34426872832 [Note] /usr/local/libexec/mysqld (mysqld 10.1.13-MariaDB) starting as process 22580 ... 2016-06-02 8:00:34 34426872832 [Warning] You need to use --log-bin to make --binlog-format work. 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Using mutexes to ref count buffer pool pages 2016-06-02 8:00:34 34426872832 [Note] InnoDB: The InnoDB memory heap is disabled 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Mutexes and rw_locks use GCC atomic builtins 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Memory barrier is not used 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Compressed tables use zlib 1.2.8 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Using SSE crc32 instructions 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Initializing buffer pool, size = 122.0M 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Completed initialization of buffer pool 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Highest supported file format is Barracuda. 2016-06-02 8:00:34 34426872832 [Note] InnoDB: 128 rollback segment(s) are active. 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Waiting for purge to start 2016-06-02 8:00:34 34426872832 [Note] InnoDB: Percona XtraDB (http://www.percona.com) 5.6.28-76.1 started; log sequence number 1616955 2016-06-02 8:00:34 34426872832 [Note] Plugin 'FEEDBACK' is disabled. 2016-06-02 8:00:34 34426899456 [Note] InnoDB: Dumping buffer pool(s) not yet started 2016-06-02 8:00:34 34426872832 [Note] Server socket created on IP: '0.0.0.0'. 2016-06-02 8:00:34 34426872832 [Note] /usr/local/libexec/mysqld: ready for connections.
