What does this mean in SVN? - Error writing to '.'

svn up
svn: Error writing to '.'
svn: Can't write to file '.svn/开发者_StackOverflow中文版tmp/entries': No space left on device

If my box is out of hard drive space, that is impossible, because it has 620GB of HD.

You probably don't have space on the disk where is the svn tree. What is output of df . in that directory?

Maybe your hard disk is partitioned. Check the partition that svn is trying to write on for the amount of available space.

If you are 100% sure you have space left, try quota to see whether you have exceeded the quota for your user account.

That may be, but how is your drive partitioned and what folders mount where on your paratitions. Do a "df -h" at the command line to see... and then decide.
