NT_STATUS_NOT_SUPPORTED - proceeding with normal close

[mdub77]

Hi,

I'm running a network windows application on a samba share with truenas and I'm getting the following errors in the logs :

Failed to disconnect durable handle for file CDWPRG/COMMUN/C_GRPERS.mdb: NT_STATUS_NOT_SUPPORTED - proceeding with normal close
[2022/04/21 20:25:16.675488, 1] ../../source3/smbd/close.c:758(close_normal_file)

And

[2022/04/22 04:01:35.053590, 1] ../../source3/smbd/scavenger.c:486(scavenger_timer)
scavenger_timer: Failed to cleanup share modes and byte range locks for file 14836696510888345722:257919:0 open 703080349

It's an old app based on Access 97 databases (MDB format) in which I notice more errors than usual ever since I migrated it to truenas from a Windows server share.

The following options are selected for this share :
- Enable ACL
- Browseable to Network Clients
- Enable Shadow Copies
- Enable Alternate Data Streams
- Enable SMB2/3 Durable Handles

Is there anything I can do to prevent these errors ?

Forgot to add the truenas server is joined to Active Directory.

You can turn off durable handles for the share.
