Agreed, but none the less the use of ADS and the content size is outside of my control and 64kb has proven to be sufficient. Microsoft tends to support deprecated features for an extended period of time, so support is needed for the forseeable future. cache does not strip. Attempting to write a file with a larger extended attribute than is supported by the file system results in 'disk full' errors. Yes, files are fine without the ADS data. The ADS data is related to endpoint security running on the client. That can't be changed so there isn't any point to go into further details. I've seen that and attempted to modify the configuration on Unraid. For better or worse the Unraid configuration is not coming from a typical configuration file like smb-extra.conf. As far as I can tell it gets cobbled together from Unraid internals and values entered in the Unraid UI. Perhaps more details on this are out there somewhere. As a result, my attempts to edit the configuration are overwritten as seen by inspecting the configuration of the actual running server.

I have a situation where we have Windows client using NTFS and some endpoint software which is storing stuff in alternate data streams (ADS) on the files. These files can be copied to and from XFS backed shares on the Unraid system without issue, however they fail on Btrfs backed shares. This is a problem because we run an XFS array behind a Btrfs cache. The reason that it works on XFS but not Btrfs appears to be that XFS has a larger extended attribute size limit. So, a work around is to turn off the cache. Not ideal. What I would like to do is to turn of ADS support on the server for certain shares, the data in the stream is transient and we don't care about keeping it. We don't however have a feasible option to do anything on the client side to auto scrub the ADS before writing to Unraid. My understanding is that you would typically use "streams support = no" in smb-extra.conf to disable ADS support on a SMB server. I however can't find any examples of doing this on Unraid, and when I try to set it the share gets set to unavailable. smb-extra.conf [MyShare] streams support = no Any suggestions? Thanks
