Can't delete or copy NFS Share from Coreelec

I have a NAS with OMV and a TV Box with Coreelec. In NFS share the options are rw,subtree_check,insecure. If i try to reach the NFS share from Coreelec I can play videos. But if i want to delete something I got this message on LOG:

2021-01-12 18:53:08.691 T:3546985344 ERROR: Delete - Error( unlink call failed with “NFS: REMOVE of //windows10.cmd failed with NFS3ERR_ACCES(-13)” )

2021-01-12 18:53:08.691 T:3546985344 ERROR: Delete - Error deleting file nfs://

If i try to copy something I got this:
2021-01-12 19:21:23.544 T:3678061440 ERROR: CNFSFile::Open: Unable to open file : ‘//docker/windows10.cmd’ error : ‘open call failed with “NFS: Lookup of /docker/windows10.cmd failed with NFS3ERR_NOENT(-2)”’

I got chmod 777 on the file.The problem it with OMV, or with Coreelec, and how can I resolve it?

For Coreelec need to use “no_root_squash” option on NFS share. After that everythings work fine.

The obvious danger then being, potentially, anyone using your device can delete items from your NFS share :thinking:
