Hello,
I have a script which utilizes smbclient to transfer files across to a CIFS
shares from my Red Hat Linux 7.x servers on a daily basis.
Mounting of CIFS shares work fine to transfer but this is for some reason
not to be implemented.
I have the following version of samba-client
Loaded plugins: langpacks, product-id, rhnplugin, search-disabled-repos,
subscription-manager
This system is receiving updates from RHN Classic or Red Hat Satellite.
Installed Packages
Name : samba-client
Arch : x86_64
Version : 4.4.4
Release : 9.el7
Size : 1.7 M
Repo : installed
>From repo : ramesh-clone-v7
Summary : Samba client programs
URL : http://www.samba.org/
License : GPLv3+ and LGPLv3+
Description : The samba-client package provides some SMB/CIFS clients to
complement ……
Unfortunately this was working fine to a 7Mode NetApp CIFS share and still
works but does not work with any of the NetApp CDOT CIFS share .
To test it manually it connect fine to the CIFS share
However if I transfer files it transfers successfully any files below 64
kbytes but comes up with "cli_push returned NT_STATUS_INVALID_PARAMETER"
when the files are bigger than this.
When this error occurs it creates an empty/Null file with the same name at
the CIFS share.
Anyone come across this problem and if so what is the solution.
You don't need a complete samba install just the smbclient install should
be enough to test this.
You can connect to the CIFS share from the Linux box using the following
command
#smbclient //CIFS_SERVER_NAME/CIFS_SHARE_NAME -U AD_Domain\\Username
This will prompt for password
smb: \>
smb: \> put SMALL
putting file SMALL as \SMALL (10128.9 kb/s) (average 10129.1 kb/s)
smb: \> put BIG
cli_push returned NT_STATUS_INVALID_PARAMETER
putting file BIG as \BIG (86067.4 kb/s) (average 64973.9 kb/s)
smb: \>
File sizes
52K SMALL
1.1M BIG
SMALL file is transferred successfully to the destination CIFS share
BIG file just creates a null or empty file with the name BIG at the
destination CIFS share location
If you connect to a 7Mode NetApp FAS controller providing the CIFS share
this works fine for any file sizes as shown below.
smb: \> put SMALL
putting file SMALL as \SMALL (405.2 kb/s) (average 405.2 kb/s)
smb: \> put BIG
putting file BIG as \BIG (6216.0 kb/s) (average 3834.5 kb/s)
smb: \>
Any help would be appreciated.
Cheers,
Ramesh
