NVR not deleting files via NFS

I have a Hikvision NVR that mounts an NFS share from my Ultra 4 running 4.2.30. The NVR is set up to delete camera video files that are more than 7 days old. When I look at the NVR admin page that ...

Hello atebit,

Have you tried refreshing the connection between the NVR and ReadyNAS? Like rebooting both and see if there is any difference.

I do not have idea what could be causing it, to be honest. It is like it is not really communicating well with the NAS. Maybe you can also try checking if you will be able to access the share through SMB or CIFS and see if the video files were really deleted or not using a computer.

Hi Jenn,

I've rebooted the NVR several times, I guess I could try rebooting the NAS as well.

As I mentioned in my original post, when I browse to that share on my Mac, the files are still in fact there.

I'm pretty sure this is a NVR issue, but I told the NVR support folks that I'd post a question here just in case there was some wacky known issue.

Complete wild guess, but I've seen similar problems due to it: There may be a problem with case sensitivity in the NVR software. NFS is case sensitive (at least in the normal case) and inattention to case in the client can cause problems such as you are experiencing. Similar inattention with a Windows server would not be an issue.

Windows servers running NFS have the capability to turn off case sensitivity. If there is a way to do so on the ReadyNAS, or Linux in general, I don't know it.
