"Lost" data, but array doesnt decreased

Not sure what messages you are referring to?

 

Your diagnostics show that you have filesystem level corruption on disk 4 so you should run a check filesystem on that drive.   It might also be a good idea to run memtest as RAM issues can cause corruption.

starting receive messages that some series and movies is being removed.

Do you have an example? This is not something that Unraid does so it must be some application.

Looks like you already had a thread about this several months ago.

And which of those is giving you the message?

 

Can you tell us the exact contents of the message?

 

Maybe it's telling you it is removing them from its database because the files aren't accessible. And they aren't accessible due to corruption.

 

I noticed you have a .cfg file for a lost+found share, probably disk4 already had  some there from your earlier repair.

Its the same HDD from the last time.

I have a new spare HDD, when an HDD die, permanently.

Corruption doesn't necessarily mean a disk is bad. 

 

Did you know you had lost+found from your earlier repair? 

 

Check filesystem on disk4 from the webUI and post the output.

Everything is working now, thanks

Probably you have even more from this latest repair. Have you examined its contents? How much data does it contain?

 

Post new diagnostics with the array started in normal (not maintenance) mode.

If you decide not to, then you can consider it lost data.

 

Maybe we could give more advice

So 24.5GB on disk4 and only 236MB on disk5.

 

SMART for disk4 looks OK. Emulated disk4 is mounted now. Should be OK to rebuild to the same disk after you fix what caused it to disconnect.

 

How is disk4 connected?

  • Author

slowly rebuild, sometimes is faster

That's very slow, post current diags.

Start the array in normal (not maintenance) mode and post new diagnostics.

Install Fix Common Problems and let it scan. I have mine configured for daily scans.

 

Then we can talk about what it finds.

As you can see, Media has files on cache that will not be moved. Set it to Primary:cache; Secondary:array; Mover Action:cache->array. If you want to set it to not use cache after you get those files moved off cache that's up to you.

 

Unraid v7 will move between pools. But nothing can move open files, so to get appdata and domains moved you have to go to Settings - Docker and disable, and Settings - VM Manager and disable.

 

Set those shares appropriately so they will be moved to whichever pool you want.

 

I'll let you decide if you want to update those dockers.

 

As already seen, not much in lost+found, if you can identify any of it you can rename and move it back to where it belongs. Linux 'file' command can help figure out what kind of data is in a file so you can try to open it in an appropriate application.
