[TiDB Version] V5.4.0\V6.1.0
[Encountered Issue]
The TiFlash disk information displayed in the Dashboard shows a non-data directory. Initially, it was normal, but after mounting a relatively large backup disk, it started displaying that backup disk. It seems to display the larger disk. The TiKV nodes also have backup disks mounted, but their display is normal.

V5.4.0:

There is indeed this problem, showing an error. I mounted an NFS.
