SQLSTATE[HY000]: General error: 11 database disk image is malformed [Solved]

by Jilu Joseph | Aug 25, 2019

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.

At Bobcares, we often get requests from our customers to fix SQLite database corruption errors as part of our Server Management Services.

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

From our experience in managing servers, we’ve seen that the reasons for database corruption may vary depending on the system settings. It relies much on the applications and OS used in the server.

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.

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.

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:

When the same error occurs on a server without a control panel, the fix differs. We export the schema and data of the SQLite database. Further, we a new database, import the schema and data.

This will export the database in SQL format.
Further, we add a new database, import the schema and data.

Sqlite error 11 malformed database schema

Post by Thomas Lohrum » Thu Oct 22, 2015 11:47 am

this is the first crash corrupting my database for a long time. However, it is a bad one. Directly importing from the corrupted database will fail. Nor can it be opened to export it as XML.

Trying sqlite3 to rebuild (.dump & .read) it caused the following behaviour:

The notebook file «C. » was created by an older version of CintaNotes.
Do you want to upgrade it?

After upgrading i get the following error:

The notebook file «C. » was created by a older version of CintaNotes and cannot be upgraded.
Error message: SQLite error 1:
there is already another table or index with this name: NoteCache

I think this is a bug.

Any ideas how to fix the database (other than restoring a backup)?

With 3010 i get the error: «Notebook format version 3010 not yet supported».

With 2950 it runs fine.

Will you change something, so this manual handling can be avoided in the future?

Next i did an export of my restored and the re-created database. I wanted to diff, so i can track, whether data got lost or not. However, the export result is unordered, thus diffing is not possible.

Can you add an order by, so this will be possible?

Thanks for your help.

Yes, the last database schema version is actually less than 3010, so it’s good that you tried 2950 as well.

Yes, the change is trivial. CN will treat user version 0 as equal to the last one.

I am experiencing a similar issue. Unfortunately it won’t fix by now !

It started yesterday with a «database malformed . 11» error everytime I tried to save a new note or a modified one (reading was ok, as well as editing a note, as long as I don’t save it). I couldn’t export anything either (error message).

Today I tried to repair it with sqlite3 (to which I am a beginner).
The first integrity check reported 2 pages never used, «on tree .. page . cell 0 : a bad ptr map entry key. » and a «wrong # of entries in index ix_Notes_Tags_tagid».
So I used sqlite3 to dump the whole database, and rebuilt it with the command line.

Just like Thomas, I had then to change the user_version to 2950 to overcome the «older version» error message.
But now that I can acess the database. new or modifed notes still won’t save ! I get the same original message «database malformed. 11».
Which is strange is that now an integrity_check on the rebuilt database returns «ok» though.
Any idea how to avoid restoring back to last week?
