That is most likely the partition that you are attempting to save the blockchain to... it is only 230GB total size... and currently only has 15GB free...tmpfs 1,2G 9,7M 1,2G 1% /run

You can double check by switching to the /media/genericusername folder and doing: df -h .
(don't forget the .)
If that is the case, then I don't think you have enough spare room to download the whole blockchain anyway... you've only got 15GB free... but there is a chance that your blk00299.dat is either corrupted or there is a physical problem with your drive (ie. bad sectors etc)
Make a copy of the blk00299.dat file to another directory, then delete it from the blocks directory and try syncing again.
