This is dedupe phase II which was introduced in 5.6.47 Now windows is aware of deduped (compressed) files and explorer is displaying them in blue. In Phase II, if you use windows explorer compressing a single file on a deduped enabled FS, it will be compressed using the DART dedupe functionality ...  If you set -cifs_compression_enabled no all files in the FS will be decompressed. This is why the color is changing. Then you can no longer apply the compression for files of this FS in Windows explorer, the error message is:  An error occurred applying attributes to this file:  Pathname  Compression is disabled for this volume.

I just upgraded from 5.6.45 to 5.6.49 and noticed that compressed and/or deduped files are now displayed in blue color.  If dedupe was introduced in 5.6.43 why did we not see this color coding before ?  if i run this command, do i disable color coding or do i actually disable compression functionality (and dedupe is still enabled ? )   fs_dedupe -default -set server_2 -cifs_compression_enabled no   Thanks
Deduped files and blue color
