Solving one type of access denied errors during duplication

[Pafegori]

Hi!

I don't have a question, but a solution to a problem I encounted.

I encounted the following issue for a few files (10s out of a million files)

 

11:11:11.1: Warning: 0 : [FileDuplication] Error checking file for duplication consistency or duplicating file \\?\GLOBALROOT\Device\HarddiskVolumeXX\<...>. Zugriff verweigert

"Zugriff verweigert" is "access denied" localized.

It took me a while to figure out what caused it. In my case there are three conditions to trigger it:

• have 2 duplicated files with a different file modification time
• the difference in file mod time has to be greater than 60 seconds
• the file must be read-only (not by ACL, just the normal file system flag)

To solve it I just temporarily removed the read-only flag.

My suggestion for the drivepool software:

• Either improve the error message to include the real reason for the duplication error (in the UI and the log)
• Or ignore the read-only flag and temporarily remove it before aligning the modification dates

Could you open a ticket at https://stablebit.com/contact ? 

There are some additional logs to collect (just in case it's a system specific issue), and that is the best place/way to do so.
