Recent releases of hdparm also support sending down TRIM commands and have a script that maps the unused blocks of the fs to trim them. Someone even posted a gui on the ocz forums that monitors the amount of data written to the fs since the last trim and reminds you to run another pass. The script can trim the fs while it is online by creating a large temporary file to occupy the remaining free space, mapping the blocks it is allocated, and trimming those. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
