After the latest update to OS build 227 on ROCK, my ROCK has a slight issue. Everytime I restart/reboot the ROCK server, I keep missing one or two albums. I noticed the number of albums is 1 or 2 less than what I had and if I checked on Clean Up Library on Library Maintenance there was some “Clean Up xxx deleted files” and the xxx number is always diffefent everytime I restart.
What I did first is try to restore the database. But, I tried several times but failed with an error message (The error message has a typo as well, “databses” instead of “databases” see attached photo, sorry did not do a screenshot at the time).
I did not know what happened, at one time I did manage to initiate the restore progress but the database did not restore because it happened so fast and no progress percentage was shown and the edit to the database that I did after my last backup was still intact.
I finally reinstall the OS using the latest build 227 and after that I could restore the database succesfully. But even then with every reboot, there is 1 or two album is missing. The only way to regain the missing albums is by manually forcing a rescan on the NAS folder.
I do not know which albums are missing. But I think they are different albums because when I look at the “Clean up xx deleted files” in Library Maintenance, the xx numbers vary from each restart and it also vary from each folder.
I use Synology DS-418j NAS. It has 4 drives (3x 8TB and 1x 4TB), 3 of the drives are used for music files and each drive is allocated 2 shared folders. I have tried to force rescan each folder one by one and see which folders and/or which drive creates the problems by looking at the number of “Clean up xx deleted files” change after each force rescan. But, apparently no one specific folder is the cause so I am quite for certain it does not come from any certain drive or folder.
Can you please share a screenshot of your Roon Settings -> Storage folder?
Also, please share a screenshot of your Overview tab before and after a reboot and note the exact local time + date that you reboot your ROCK at. I can then enable diagnostics mode and see if logs have any further clues.
Yesterday (24th August 2020, 17:30pm my local time) I restarted the Roon OS. After a few minutes, I force rescan all the folders to make sure all the files are accounted for. And then I do a screen capture of the overview.
While we’re at it, everytime I do a restart there is always 6 files that are reanalyzed. I narrowed it down to folder \Music-NAS\Music_5 but do not know which ones. This has happened long way back. No big deal, just curious if you also track them down.
I did one fresh reinstall using USB with the latest version of ROCK just for the heck of it, restore the database. And afterward, I tried to reset the database, but I failed again although I could do a restore from a backup. But, I could not reset the database. When I first installed ROCK last year, I played with it to get acquainted with the system; I did a backup, and I did a restore just to make sure that the backup works before I invest more time into editing my database. With last year version, I could do a database reset. Not this year (with the latest update at least).
