Frigate NFS mount point trouble

I had frigate writing to an NFS share on my network, and today a power failure knocked everything offline. When the system came back up, frigate will no longer write to the NFS share, and instead re-creates a new set of files in the mount point folder on the HA host. I’m using Home Assistant 2023.6.2
I can see the NFS share advertised via another host on the network via showmount.

Is there no way to delete the frigate folder from the media folder? I couldn’t see a way to do it in the UI. I used the samba add-on to remove all the files from the mount point folder before trying to re-mount the NFS share from my storage machine. The NFS share seems to mount using the Storage function/feature of HA, but frigate chooses to write the files locally.

Has anyone got a solution for this?

a little more information… I have a raspberry pi 4 as my cam storage machine. it has a USB3 attached md raid5 disk. I made an NFS share at /store1/frigate. Everything was working before the power failure.

root@camstore:~# showmount -e

… and just like that. Last night brought another storm with a power outage. When I brought HA up this time it mounted the NFS share from 11 days ago. I tried rebooting several times earlier in the past couple of weeks trying to get frigate to use the share.

There have been a couple of updates since the original problem, but I didn’t recall seeing anything related to my situation. I’m glad it’s back, but I worry for how long?
