[linux-cifs-client] write problem to NAS - cp is fine, rsync fails

[Michael Geiger]

Hello, I have a problem writing to a NAS and I hope someone can help me here:

I'm using OpenSUSE 11.1 64bit with a vanilla kernel 2.6.28.5 - the only patch
applied is this one to solve the mount problem I had with this NAS:
http://bugzilla.kernel.org/show_bug.cgi?id=10451

The NAS device is a Raidsonic ICY BOX IB-NAS900, latest firmware. The NAS is
mounted with this fstab entry:

//elenas/musik /mnt/ele cifs noauto,credentials=/etc/fstab.cred.ele,
   uid=share,gid=users,file_mode=0664,dir_mode=0775,noacl,nounix,nosfu,
   iocharset=iso8859-1 0 0


Reading files works perfect (except some "CIFS VFS: ignoring corrupt resume
name" showing up), I have mirrored 20 GB using rsync without a problem. But
whenever I'm writing files with rsync I get these errors after some seconds:

Feb 20 15:32:08 box2 kernel:  CIFS VFS: server not responding
Feb 20 15:32:08 box2 kernel:  CIFS VFS: No response for cmd 50 mid 158

Feb 20 15:51:38 box2 kernel:  CIFS VFS: Write2 ret -11, wrote 0


But when I copy files with unix cp the files are copied on the NAS, no errors!

Any ideas?
