Volume: Bit Rot heeft een fout gedetecteerd in /data/Klanten/..../... en kan de fout niet verhelpen
Hello I have a ready nas 102 that produced errors some weeks ago: " Toename geconstateerd van aantal ATA-fouten: [708] op schijf 1 (Internal) [TOSHIBA DT01ACA100, 43R5ULENS] 12 maal in de afgelopen...

Thank you for your reply.
What I did is:
- I took a backup (weekly/daily)
- I added a new disk. So there was an old one and a new one. Made sure it was replicated (Raid1)
- I removed the old one and replaced it also with a new one. Made sure it was replicated (Raid1)
Everything looked ok.
Now I have the Bit Rot problem. Strange is that I have it only for files created or changed the last year. (Or maybe it is checked by date, going back).
Currently I am restoring my last backup (That one of yesterday evening). I just kopie the files manually back (overwrite) and it looks like the system accepts the files. (We can open the files again).
I will restore all affected directories and try like that. If some files are lost, it is not really a problem. If that does not work, I will buy another NAS and restore. Something I had to do before. The NAS is heavily used (growing company) and is working fine now for more than 2 years. It is "to-be-replaced". (Also because I have performance issues). Might go to an online solution (the cloud in). The reason why I have the NAS is because I run (already for 9 years) an MS Access database on it (10 simultanous users). I made the DB 9 years ago, thinking it will be good for 1 year, and it is still running and working like I want it. So I might go to a more <server>-based architecture and use the cloud for file storage only (lots of pictures, plans, pdf-documents). Building company.
I am only scared that some process or program is creating the Bit Rot problem. If this is not the case, it is solvable.
Thanks again for the reply.
I will do an update of this topic if the problem is solved (or if not).
Regards

I still have a question: Is there a possibility to check data-integrity or errors? Some tool or option I can use?
Thanks

If you are using RAID with redundancy, you can to a scrub, which has some level of checking.
I don't know an option to verify the BTRFS checksums - that would be useful thing to add to the maintenance tests. Perhaps suggest that in the Idea Exchange in the forum.
