ReadyNAS Pro - file/folder access permissions
Hi everyone, I've contacted Netgear support about this issue but they are too slow so I thought I'd try my luck here. I work for an IT management company and I manage the ReadyNAS Pro for one of...
@Klayson - you've identified what I expect to be the OP's issue, but rather than assume I asked for the full overview.
Re the Ownership changes you see: There are a number of applications that, when editing a file, make a temporary copy of the original file, apply edits to the temporary copy, and then when the file is saved the original file is deleted and the temporary file being worked on renamed with the original file name. (MS Office apps seem to work this way)
This is a "safety" feature to prevent file corruption as the original file is never edited directly, but it has the side effect that in reality the editing user creates a new file and so the rights and ownership are assigned according to the editing user.
With that in mind, the other issue that the OP may then be experiencing is if users with different primary groups are creating & editing files which, if the above method is used, would result in a group change after the file is edited, and irrespective of the "Automatically set permissions on new files and folders" settings for groups may make the file inaccessible. The only practical solution here is to also ensure everyone permissions are set to read/write.
Hope that makes sense
