Apps Not Recognizing Merged Disk Space in CasaOS

There appears to be an issue with the disks merging feature in CasaOS. While the merging of disks seems to work correctly, applications only recognize the disk space of the main storage disk and do not account for the total merged disk space. This results in inaccurate disk space reporting within apps.

To Reproduce

Steps to reproduce the behavior:

1. Merge multiple disks using CasaOS's disk merging feature.
2. Open any application that displays or utilizes disk space information (In my case its sonarr)
3. Observe that the application only recognizes the disk space of the main storage disk, not the total of the merged disks.
4. This results in a discrepancy in disk space reporting.

Expected behavior

The expected behavior is that after merging disks in CasaOS, all applications should recognize and utilize the total combined disk space of the merged disks, not just the main storage disk.

The merge disk feature of CasaOS was designed to be merged into the /DATA directory. So the space you see on the system disk is still the original size.

I think after merged the storages it should using the external storages instead of still target to the main storage.

I have the same issue, the difference is it used to work until recent restart of the server. Disks still show as merged, but when I open any app it can't see the data. I can see the data in Files explorer but only on the merged disk, not as a whole.

I fixed this by manually moving all the movies and whatnot to /DATA from the secondary disk and /var/lib/casaos/files, truncating tables o_merge and o_merge_disk in /var/lib/casaos/db/local-storage.db, restarting the server, formatting the secondary disk and re-merging it back to the system disk. I was lucky that all of the data could temporarily fit on the main disk. If it can't you will have to backup elsewhere first.

The reason I had to fiddle with local-storage.db was because I could not re-merge in the UI.
