Not sure about right ML (maybe fs@), feel free to forward to another
one if needed. And please Cc: me.
Background:
- I need to syncronize two dir hosted on win machines based on data
contained into an Oracle DB (direction of copy may change based on
owner of file as specified into the DB). I made an sh script that
generate a big Makefile with right direction of cp -p but it fail
copying a lot of identical file (identical means same md5 and with
date of past, already copied previous night (and previous and...).
(a lot of fuzzy word, problem is timestamping a remote smb file).
Environment:
- a freebsd machine (I tested on 4.9-STABLE and 4.10-STABLE)
- at least a real win machine with a NTFS exported share (my real
case has one w2k-server and one wnt4-server).
How to reproduce:
- create a mount point, mount_smb the win share, touch a file
// on the mount point (or at any level deep):
// (you can also change example time but please use even/odd seconds)
//
# foreach s ( `jot -w%02d 10` )
foreach? touch -t 200401020304.${s} sample${s}
foreach? end
# ls -lnT sample*

Any date&time will be rounded up to previous even second :-(
If you create a file from the win-side (with touch or notepad or
with your favourite tool) you can specify odd seconds, this means
that is not a NTFS struct limitations (maybe :-).
Who round my time? I need this for an exotic job: syncronize two
win machine using data from an Oracle DB. My approach was using
a Makefile but every night it copies hundreds of already copied
files and it use an expensive WAN link. Yes, I can switch to more
robust check, md5 signatures, extraction of time and manual check
with rounded values, but any other approach leave this problem...
