One of the best database engines for most low to medium traffic websites is SQLite. Many popular applications like Horde webmail, CakePHP, etc. make use of it.
However, the SQLite database users often face various errors leading to corruption. One such error is,
SQLSTATE[HY000]: General error: 11 database disk image is malformed.
Today, this write-up describes how our Support Engineers fix SQLite database corruption errors.
What causes corruption in SQLite?
We’ll begin by checking on the major reasons that can corrupt the SQLite database.
SQLite allows simultaneous access from different applications. And, when there is heavy use of the SQLite database, then there are hefty chances for database corruption. Usually, this corruption occurs due to database bugs or even hardware failure.
Similarly, regular use of the SQLite database leads to a large amount of data. And, when the size increase over the well-defined limit, it ends up in error SQLite Database Disk Image Is Malformed.
How we fixed “General error: 11 database disk image is malformed“
Now, let’s see the topmost reason for these SQLite database corruption errors and how our Support Team solved these errors.
Recently, one of our customers had an error while trying to access their emails via webmail.
The error said,
A fatal error has occurred SQLSTATE[HY000]: General error: 11 database disk image is malformed Details have been logged for the administrator.
Here, the customer was using the Horde webmail panel.
On checking our Support Engineers found that horde.sqlite database was corrupt. And, this resulted in the error.
[19:52:46 cp01 root@xxx]# /usr/local/cpanel/3rdparty/bin/sqlite3 horde.sqlite SQLite version 3.27.1 2019-02-08 13:17:39 Enter ".help" for usage hints. sqlite> .table Error: database disk image is malformed sqlite> .quit
As the database was already corrupt, the easiest fix was to recreate it.
Therefore, we solved the error by removing the corrupted database file and recreated a new database using:
sqlite> .mode insert sqlite> .output mydb_dump.sql sqlite> .dumpsqlite> .exit
This will export the database in SQL format.
Further, we add a new database, import the schema and data.
sqlite3 mydb.db < mydb_dump.sql
Finally, we update the statistics for the indexes in the databases.
That’s it. We now have a working SQLite database.
