OperationalError: disk I/O error

[Emmanuel Blot]

You'd better run stop all your network services right now, and start a check filesystem session on your hard drive as well as a SMART test, it looks like you have a hardware issue…

You may also want to look at your system log files to see if you can find other information about this issue that could look like a harddrive failure.

Just for the record, it might also be a simple "disk full" issue.

disk I/O error ?

Please have a look at the possible reasons for this message (assuming you're using SQLite): from ​http://www.sqlite.org/c_interface.html:

SQLITE_IOERR

    This value is returned if the operating system informs SQLite
    that it is unable to perform some disk I/O operation. 
    This could mean that there is no more space left on the disk.

Replying to cboos:

Just for the record, it might also be a simple "disk full" issue. disk I/O error ?

It would be less alarming ;-)

I thought the SQLite error was, in this case

DatabaseError: database or disk is full

[pmocek-edgewall-tracwiki@…]

The file system on which the Trac environment resides was full. Definitely not a Trac defect.

I encountered this issue because the SQLite Database is located on a network share. Once the network share becomes unavailable for a short period of time for whatever reason, this error occurs.
