smb_panic and core dump...

Post by anicesteak »

I set up a new Geom Raid5 and the file transfer keeps failing because of a network error (that's what Windoze says on the file copy).

So I look up the log on Nas4Free, and I see panic/reboot. Is this a config issue or a bug? I would hope that a config issue could not cause a panic...

Check your samba settings: if you are using smb2, make sure AIO (asyncronous I/O) option is disabled.

Also, can you give us more info about your setup? version?

Yes, using smb2, AIO was enabled so I disabled it.

That was the crux of the problem, if you search these forums there are many topics about it.
Its a samba limitation, not NAS4Free
Hope you don't have any more problems!
