Did someone of you find a solution for our problerm ???
I send you the documented as you asked it but I always got the same
problems. I tried some possibilites for optimizing my system but I always
stay with my problem for writing files. Reading files from my shares is not
a problem but writing causes "buffers" problems with windows and windows
says he could not write all the blocks.
Since our last mail, I changed two things on my server. I upgraded it from
ext2 to reiserfs ( it seems it is better ??? ) and I worked with blocks of
2048 bytes in ext2 and I heard it was better to upgrade them to 4096.
I am surprised with such a problem because I am the only one using samba
here at the moment and my server is using U-160 SCSI interface so it should
not cause these strange problems.
Thanks for your help.
Vincent
