I am sharing a folder from OpenMediaVault 3.0 to Ubuntu using NFS.It mounts, and I can see the files in it.  I can create folders and copy to the mount through the Ubuntu GUI file browser.However, if I try to mkdir, cp, or rsync to it, I get Permission Denied whether I use sudo or not.I ensured that the server and client both have the same username, UID and GID.Do you know why this may be the case?  And how I can mount with full permissions?media@media-vm:~$ df -hFilesystem                     Size  Used Avail Use% Mounted onudev                           7.9G     0  7.9G   0% /devtmpfs                          1.6G   10M  1.6G   1% /run/dev/sda1                       16G  6.8G  8.2G  46% /tmpfs                          7.9G   16K  7.9G   1% /dev/shmtmpfs                          5.0M     0  5.0M   0% /run/locktmpfs                          7.9G     0  7.9G   0% /sys/fs/cgroup/dev/sdb1                      7.0T  3.1T  3.6T  47% /7TBtmpfs                          1.6G  144K  1.6G   1% /run/user/100010.0.1.73:/export/MediaBackup  5.5T  217G  5.2T   4% /mnt/MediaBackupCommand to mount:media@media-vm:~$ sudo mount -t nfs 10.0.1.73:/MergerFS/ /mnt/nfs/MergerFS/From nano /etc/exports on OMV3:/export/MediaBackup (fsid=3,rw,subtree_check,secure)Mount information:media@media-vm:~$ ls -ld /mnt/MediaBackup/drwxrwsr-x 3 root users 4096 May  3 15:42 /mnt/MediaBackup/Copy attempt sudo:media@media-vm:/7TB$ sudo cp -r Movies/ /mnt/MediaBackup cp: cannot create directory 'mnt/MediaBackup/Movies': Permission denied
Mounted NFS share. Can create folders in file browser, but mkdir doesn't work through terminal
