Subject Re: lost+found files prevent DataNode formatting
Date Tue, 29 Sep 2009 03:43:52 GMT
Those are created by fsck and will come back.  They belong to the
filesystem and you shouldn't delete them.

Instead, create subdirectories on those mount points and use them as
DFS directories.  E.g. create and use /mnt/dfs instead of /mnt

Cheers,
Anthony
