Copy from FreeNAS via CIFS fails

[eltoro]

Hi,

I have starting to experience some problems with my FreeNAS 8.0.4 Release. When copying files to my client computer running Windows 7 via CIFS I pretty often get "File descriptor" errors or "File not available". Restart of the NAS-box did not help and restart of the client did not work either. I have one auxillirary parameter saying smb max protokol is smb2..

But when transferring via AFP to my Mac works. So it seems to have something to do with CIFS.

Has anyone experianced this?

I see the following message in the log:

Apr 27 07:19:35 eltoro-storage kernel: pid 2857 (smbd), uid 0: exited on signal 6
Apr 27 07:19:37 eltoro-storage kernel: pid 2858 (smbd), uid 0: exited on signal 6
Apr 27 07:20:16 eltoro-storage kernel: pid 2859 (smbd), uid 0: exited on signal 6

And this is from log.smbd

Hi Eltoro,

I think you might have found a bug. I've used the max protocol=smb2 also and haven't seen this problem.

[sjieke]

I've also seen smbd crash on my server when using 'max protocol=smb2', but only when using a Windows7 client.
Using a linux client doesn't crash the server. I think it is because only the Win7 clients are effectively using the SMB2 protocol, other clients still use the default protocol. Removing the auxiliary parameter solved the issue for me, so I'm pretty sure that that parameter causes the issue. I will try enabling SMB2 again when FreeNAS 8.2 is released and I have upgraded.

[eltoro]

Ok, it probably has something to do with SMB2 since my Linux-box with XBMC never showed any errors reading the files either...I´ll disable SMB2 support instead :-(

Actually, I think I posted my question in the wrong category. My intention was to post it in the Sharing category. Sorry for that...

[ProtoSD]

You did post it in sharing, I moved it because it's more likely a bug. I also have Windows 7 and didn't have this happen. I just checked and I have it disabled at the moment because I was experimenting with some settings.
