I'm not able to use neither the --attrs nor --timestamps otions with the following command: net rpc share migrate files public -U administrator -S src.example.com --destination=dst.example.com --acls --attrs --timestamps -v For --attrs, the command exits immediately with the following error: ------------ syncing [public] files and directories including ACLs, including DOS Attributes failed to set file-attrs: NT_STATUS_ACCESS_DENIED Could handle directory attributes for top level directory of share public. Error NT_STATUS_ACCESS_DENIED Could not handle the top level directory permissions for the share: public ------------ For --timestamps, the command exits immediately with the following error: ------------ syncing [public] files and directories including ACLs, without DOS Attributes (preserving timestamps) failed to set file-attrs (timestamps): NT_STATUS_ACCESS_DENIED Could handle directory attributes for top level directory of share public. Error NT_STATUS_ACCESS_DENIED Could not handle the top level directory permissions for the share: public ------------ But that command operates only on shares, so if it cannot set such attributes in the top level directory, how can i use those parameters at all? I suspect the problem is with the "net" program not samba server, because the same errors occurs even if i try to migrate one share to a Windows PC. If the fix would not too easy to implement, can't be added a new --ignore-toplevel parameters to skip the top level directory and continue with everything else? Searching on your technical mailing list and in your bug tracker, i've found: - this ignored message from 2008 (not really the same problem but seems related): http://lists.samba.org/archive/samba/2008-December/145290.html - this interesting migration guide, splitted in two message. The most interesting part is the second, where the author had to patch and recompile samba source in order to workaround the error mentioned here and complete his migration: http://lists.samba.org/archive/samba/2010-December/160073.html http://lists.samba.org/archive/samba/2010-October/160074.html If needed i can post smb.conf and other details at your request.
