I'm trying to track a bug which corrupted some tables in mysql and I need to know, what happens if /tmp gets full at the same time some update query executes, will it fail? If does, where does this get logged? If doesn't is there a way to log that?

Thank you!

  • Your question was very difficult to decipher so I edited to make it more legible, is that still asking the same question? – Adam Sep 25 '14 at 21:31

I understand that you want to know what happens to an application attempting to write to a file if the disk is full.

The answer is that the write() call will return ENOSPC.

How a particular application responds to that error will vary, but for mysql it appears it will throw an error similar to the following: Error writing file '/var/log/mysql.log' (Errcode :28)

Where perror 28 shows : OS error code 28: No space left on device
