Hi, I have a really strange problem. smb server: 3.0.10-1.fc3 smb client: 3.0.23c-2 (fc6, same problem with fc5) fstab entry on client: //10.0.0.1/data /pinguin_data cifs credentials... some directories in /pinguin_data are accessible and some are not. all permissions on the serve side are the same. I get the following error message:> bash-3.1$ ls /pinguin_data/abc/ls: reading directory /pinguin_data/abc/: Invalid argument> bash-3.1$ ls /pinguin_data/def/...works fine I tried to remove all files in the abc directory. after this step, the directory was accessible again. I searched for strange characters but then I found out, that the problem depends on the number and size of files in the directory (limit is about 70 files and 500MB). logs don't tell me anything... a few weeks ago, everything works fine - perhaps a smb client update (yum) is responsible, but I am not sure. another interesting detail is, that accessing the directories from a windows machine doesn't show any errors, everything works fine there. anybody some clues? thanks Wolfgang
