It means that the special program that creates the unified user shares tries to read some directory entries that has been removed.

 

And since the files it complains about has file names ending with ".tmp", it sounds like files that has a very short life span.

So, is it something to worry about?!

@pwm is correct.  It means a user share directory listing was requested, which will look for that directory on all devices and "merge" their contents into a single listing.  The error occurs when a directory is opened on a particular device in order to scan it, and at time directory was opened those files existed, but when code got around to checking what kind of entry it was (file or another dir), the file has been deleted.  The message is informational and if you find your syslog fills up we can consider getting rid of it.

Hmm, i dont know, everytime i look into log, i find one of those. I guess its bc of radarr or sonarr which moves files around?!

Hmm i would suggest to rename it from ERROR to NOTICE.

 

Maybe also remove it, except u have enabled debug logging. Bc if its nothing bad, why display..

Everytime i look into my log, i get this.

 

It's tricky what is a severe issue and what should be seen as a notice.

 

If you use your unRAID in a way that a user share regularly sees short-lived entries, then you get lots of log entries. And they are more or less irrelevant - it's expected outcome.

If the same thing happens for long-living archival files, then it represents a severe error because archival files aren't expected to magically disappear.

Atleast if its .tmp, it should be notice, correct?

That is an important difference between computer logic and human logic - we tend to be able to understand context and make assumptions. Computer logic is quite cold and hard - it takes hard-coded rules to teach shfs all possible special patterns for what we humans considers short-lived files.

I've been having this exact same issue since RC15.

I also now after this seem to be having sata issues, but started off with these shfs_readdir errors.

I also guess its Sonarr or Radarr, or something like this.

 

Is there anything we can look into for this?

Like I say, it only started with RC15 for me, so guess its a kernal change, or some other update.

Or even the docker update, but I have no idea how to figure out where the change happened.

You think we're "chatty", ever look at windows log files?

Ehm, i dont know!

 

But yeah, i look at windows "ereignisanzeige"(dont know english) from time to time. Never saw a error about some random temp file
