Hi,

I'm running 4.8-STABLE (sources from April 7). I was dumping my =
filesystems
to files on an smbfs share (a Win2k box), and I found that dumping more =
than
4Gb in 1 file resulted in a corrupted dumpfile. So as a quick test, I =
dd'd
/dev/zero to a test file on the smbfs share to see what happened at the =
4Gb
boundary.=20

[root@britersen:/mnt/dump]# ll -h test && ll test
-rwxr-xr-x  1 root  wheel          3G May 19 20:28 test*
-rwxr-xr-x  1 root  wheel  4292345856 May 19 20:28 test*
[root@britersen:/mnt/dump]# ll -h test && ll test

-rwxr-xr-x  1 root  wheel  4295884800 May 19 20:28 test*
[root@britersen:/mnt/dump]# ll -h test && ll test

-rwxr-xr-x  1 root  wheel  4307271680 May 19 20:28 test*

Note how the humanised output suddenly wraps back to 0, and then somehow
fixes itself.

Is this a known problem with smbfs?
