Can't create or write into the data directory stored on nfs share

Hello! Sorry for the delay, I had no time before. I managed to have everything working with NextcloudAIO, but the procedure should be almost the same for you. Here are the steps I used:

First install Docker and docker-compose

Then:
Create a Nextcloud shared folder in your Synology NAS, and give the access to your Nextcloud machine using the following parameters (sorry in French):

2022-11-17_10-25-53

Go back on the Nextcloud machine and install the required packages for nfs
$ apt install nfs-common -y

Create a mount point
$ mkdir -p /mnt/nextcloud

Mount the remote NFS drive to the mount point
$ mount X.X.X.X:/NASVolumeNumber/Nextcloud /mnt/nextcloud #X.X.X.X is the IP of your NAS

Check the NFS version that is used for mounting the drive
$ mount -v | grep /mnt/nextcloud

Check that everything is correctly mounted
$ df -h

Make the mounting process activated at boot
$ nano /etc/fstab

Add:

X.X.X.X:/NASVolumeNumber/Nextcloud /mnt/nextcloud nfs x-systemd.automount 0 0 #x-systemd.automount is used to automount via systemd

Save the file

Mount all
$ mount -a

Create nextcloud data and backup directories

$ mkdir /mnt/nextcloud/ncdata
$ mkdir /mnt/nextcloud/ncbackup

Change owner for mount point in client
$ chown -R www-data:www-data /mnt/nextcloud

Change permission rules on the mount point in the client
$ chmod 755 -R /mnt/nextcloud

Optional if the permissions on the Synology where not changed with the previous commands
Connect to the Synology Server and change user and group to the mounted folder according to client’s user ID

$ sudo chgrp -R +33 /NASVolumeNumber/Nextcloud
$ sudo chown -R +33 /NASVolumeNumber/Nextcloud

Install Nextcloud AIO using docker-compose
As Root!

$ mkdir -p /home/user/Nextcloud
$ cd /home/user/Nextcloud/
$ nano docker-compose.yml

Paste

Save

Then run the docker-compose command
$ docker compose up -d

You should be good to go :smiley:
