Tom White commented on HDFS-860:
--------------------------------
Brian,
Another solution would be to return 0 if the size to truncate to is the same as
the file's size. This would cover the scp case, without breaking error codes,
no?
BTW what OS are you using? I haven't been able to reproduce this on Centos or
Ubuntu, as scp doesn't seem to be calling truncate.

> For whatever reason, scp issues a "truncate" once it's written a file to
> truncate the file to the # of bytes it has written (i.e., if a file is X
> bytes, it calls truncate(X)).
> This fails on the current fuse-dfs.
