[vdr] VDR reports wrong disk usage

Hi

My vdr recordings are stored on an openmediavault server. The vdr box (rpi 2) is given access to them by nfs.

# df -ah /mnt/mmcblk0p3/tv

Filesystem Size Used Available Use% Mounted on 192.168.0.40:/export/vdrrecords 3.6T 1.2T 2.5T 32% /mnt/mmcblk0p3/tv

VDR nevertheless wrongly reports : Total: 1:02h (1.6GB) | Free: 1:01h (1.5GB)

The problem appeared when I switched from MLD 5.1 to MLD 5.4 (VDR ver. 2.4.0) It seems like VDR kept disk usage of the SD card before mounting the nfs share in /etc/fstab.

How can I fix this ?

Thank you for helping
