Subject:
smbd errors, log is flooded
Description:
I have a Win2K8R2 machine that is accessing this server via CIFS (backup
software) and the log is just getting spammed with the following error, multiple

times a second.
My SMB config is Anonymous access on NT1, not master browser, enabled Large
Read/Write, enabled Store DOS Attributes, enabled AIO (default values)

Anyone know the meaning of this error, or how it can be corrected? its just
impossible to get anything useful out of the logs when thats all i can see.

Code: Select all

not much info available. seems that other ppl are having the similar problem with win 2k8 server

did you try the smb2 protocol?
Nas4Free 11.1.0.4.4517. Supermicro X10SLL-F, 16gb ECC, i3 4130, IBM M1015 with IT firmware. 4x 3tb WD Red, 4x 2TB Samsung F4, both GEOM AES 256 encrypted.

I have not tried SMB2 protocol yet (i really don't want to reconfigure the entire backup infrastructure adding users and authentication...)
I have another N4F server (same release) that is accessed by a Win2K8R2 box but those errors do not show up in the log. I have verified all the settings are identical. It also didn't happen with this server when running .636.

To give an update on this situation:
I hadn't really looked into the SMB2 capabilities, and didn't realize i could use "map to guest" to effectively create an anonymous share. Having done that, it seems the error has gone away, i just hope it stays away.
