Re: System Hangs on SMB Shares

Well, the workaround partly resolved the problem - so far as to get Nautilus to browse the share without hanging, but I then tried to empty the trash (which didn't contain any files taken from the share) and it hangs again.

To me this seems to be a rather serious bug - surely there must be a patch or fix to this somewhere?

My FC2 system allows me to mount SMB shares entered in /etc/fstab/ just fine. But whenever I try to access them in the Nautilus file manager, my entire file system hangs and becomes unreachable. I can still use apps such as terminal and Mozilla, but to get file management back I need to reboot my system.

Is this a known problem?

I believe this is a bug as I and others have had this problem. You can check your /var/log/messages file to see if you have a log entry similar to the following:

smb_lookup: find //.Trash-jos failed, error=-5

I found a work around from this bug report (http://bugme.osdl.org/show_bug.cgi?id=2642):

killall -STOP nautilus
smbmount //your/share  /mntpoint
killall -CONT nautilus

I can confirm that this procedure works for me as I have not had a hang since using it. You can read the bug report to get details on why this problem might be occurring. This procedure may not help you since you are using fstab to do the mounts, but as a temporary solution you could comment out the fstab entries and mount the shares manually using the procedure above.
