DSM-G600, DNS-3xx and NSA-220 Hack Forum

I have a DNS 323 NAS at home and two clients talk to it: a linux (opensuse 11.1 x86_64) box and an OS X leopard box.

linux client cifs: I mount the NAS volume using

root@linux:~# mount -t cifs -o username=anand,password=xxxxxxx  //192.168.0.6/anand /mnt/nasraid/anand/

When I try to copy files onto the device using

anand@linux:~> cp -pRv <dirname> /mnt/nasraid/anand/

the files copy over but the date/timestamps are lost. I get errors/warnings such as "cp: preserving times for `/mnt/nasraid/anand/<filename>': Invalid argument"

Additional info:

OS X client cifs: I mount the NAS volume using Finder in leopard's gui. (It explicitly says cifs and not smbfs or somesuch.)

When I try to copy files onto the device using

Macintosh-2: cp -pRv <dirname> /Volumes/anand     :this is the mount point that OS X assigns

the files copy over AND the date/timestamps are preserved. I don't get any errors/warnings.

Question: How do I get the linux client to behave more like OS X? I'd like to get date/timestamps working. Is there an option in mount.cifs that needs to be explicitly turned on? (I tried sfu but it didn't work)

I apologize if this is well known and resolved. I couldn't easily find the answer by digging around the forum archives.
