Hi,
I'm having problems copying from a local partition (vfat) to an NFS
mount, preserving timestamps.
"cp --preserve=timestamps" will *not* preserve the timestamp, with no
error given.
"rsync -t" *will* preserve the timestamp as expected. Here's what I've done:
Looking at the original file:
[EMAIL PROTECTED]:/tmp$ stat /media/flash/dcim/100canon/img_0300.jpg
File: `/media/flash/dcim/100canon/img_0300.jpg'
Size: 1807152 Blocks: 3552 IO Block: 16384 regular file
Device: 831h/2097d Inode: 1458 Links: 1
Access: (0755/-rwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)
Access: 2006-06-18 20:03:50.000000000 +0100
Modify: 2006-04-17 15:07:24.000000000 +0100
Change: 2006-05-01 23:06:24.000000000 +0100
Copying the file to /tmp using "cp --preserve=timestamps":
[EMAIL PROTECTED]:/tmp$ cp --preserve=timestamps
/media/flash/dcim/100canon/img_0300.jpg ./img_0300.jpg.cp
All looks OK:
[EMAIL PROTECTED]:/tmp$ stat img_0300.jpg.cp
File: `img_0300.jpg.cp'
Size: 1807152 Blocks: 3544 IO Block: 4096 regular file
Device: 801h/2049d Inode: 7143470 Links: 1

Change: 2006-06-18 20:10:19.000000000 +0100
Change to my home directory:
[EMAIL PROTECTED]:/tmp$ cd
I'm on an NFS mount now:
[EMAIL PROTECTED]:~$ pwd -P
/mnt/nfs/kronos/u1/home/alex
[EMAIL PROTECTED]:~$ mount
/dev/sda1 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
tmpfs on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev type tmpfs (rw,size=10M,mode=0755)
kronos:/u1 on /mnt/nfs/kronos/u1 type nfs (rw,addr=192.168.0.2)
kronos:/u2 on /mnt/nfs/kronos/u2 type nfs (rw,addr=192.168.0.2)
/dev/sdd1 on /media/flash type vfat (rw)
Now copy the file here using "cp --preserve=timestamps":
[EMAIL PROTECTED]:~$ cp --preserve=timestamps
/media/flash/dcim/100canon/img_0300.jpg ./img_0300.jpg.cp
"Modify" date has become the current time:
[EMAIL PROTECTED]:~$ stat ./img_0300.jpg.cp
File: `./img_0300.jpg.cp'
Size: 1807152 Blocks: 3544 IO Block: 32768 regular file

Modify: 2006-06-18 20:19:31.799681001 +0100
Change: 2006-06-18 20:19:31.800680835 +0100
[EMAIL PROTECTED]:~$ date
Sun Jun 18 20:19:51 BST 2006
Now use "rsync -t" to copy the file instead:
[EMAIL PROTECTED]:~$ rsync -t /media/flash/dcim/100canon/img_0300.jpg
./img_0300.jpg.rsync
"Modify" date has been preserved:
[EMAIL PROTECTED]:~$ stat ./img_0300.jpg.rsync
File: `./img_0300.jpg.rsync'

Any ideas please?
Thanks in advance,
