The Magento server I am working on was set up by another person to use database storage.
Without knowing this, I have been running an image import script which has failed now with the error
PHP Fatal error: Uncaught exception 'Mage_Eav_Model_Entity_Attribute_Exception' with message 'SQLSTATE[HY000]: General error: 1114 The table 'core_file_storage' is full'
What are my options if I cannot synchronize to file system storage?
Is it safe to truncate
core_file_storage? Does it contain anything other than images/media?
