Re: Spontaneous development of supremely large files on different ext3 filesystems



One simple point:
bash-3.2$bc -ql
obase=16
35184386120704; 14032896
200000D61C00
D62000
18014398562775391; 53297152
400000032D315F
32D4000

The filesize is basically the same, except for the addition of a stray
bit, way off in left field.   (( Note that  both of the 'old' file
sizes are multiples of 8K ))
