[Samba] shadow_copy2 prob? FSCTL..GET..DATA: max_data_count(114) too small (118) bytes needed!

[Linda Walsh]

I have "/home" as a logical volume.  I have snapshots:

 LV                  VG   Attr   LSize  Origin Snap%  Move Log Copy%  Convert
  2010.02.05-01.26.19 Home swi-ao 10.00G lvol0   39.81                        
  2010.02.06-02.37.52 Home swi-ao  5.00G lvol0    0.25                        
  lvol0               Home owi-ao  1.00T                   

and they are mounted:

/dev/mapper/Home-2010.02.05--01.26.19 on /home/snapdir/@GMT-2010.02.05-01.26.19 type xfs (ro,nouuid)
/dev/mapper/Home-2010.02.06--02.37.52 on /home/snapdir/@GMT-2010.02.06-02.37.52 type xfs (ro,nouuid)

My 'home's definitions (I have 3 shares that all resided on /home partition':

'ServHome'	(home of user on the server)
'home'		(share of the root of the share) and
'/homes'	(the per-user in Domain share) where their profiles go

Each has:
        vfs objects = recycle readahead shadow_copy2
        recycle: keeptree=true
        shadow:snapdir = /home/snapdir
        shadow:basedir = /home
01234567890123456789012345678901234567890123456789012345678901234567890123456789
Yet when I go look at files that that have been modified on the 6th, I see no
previous versions.

In /var/log/samba/clientname.log, I see:

  linw opened file mail/bind read=Yes write=No (numopen=3)
[2010/02/06 03:23:41,  0] smbd/nttrans.c:1970(call_nt_transact_ioctl)
  FSCTL_GET_SHADOW_COPY_DATA: max_data_count(114) too small (118) bytes needed!
[2010/02/06 03:23:57,  2] smbd/close.c:612(close_normal_file)
  linw closed file mail/bind (numopen=2) NT_STATUS_OK

Is the max data count too small the problem?  Is there a bug in this
version of samba?  Is this relevant?

Or is there something else wrong I don't see?

linux 2.6.27.29 on suse 11.1 
samba 3.4.3-12.1


Any insight appreciated....

Thanks,
Linda
