Nextcloud Storing Data on NAS

Mounting the data dir as a SMB share from my Synology NAS.

Creating a Mountpoint to NAS/nextcloud-data

To ensure the data from the NAS is available to the container, we have to mount the nextcloud-data directory via SMB on my docker server.

cd ~/nextcloud
sudo mount -t cifs "//NAS/nextcloud-data/data" \
         -o username="admin" \
         -o uid=www-data,gid=www-data \
         -o file_mode=0640,dir_mode=0770 \
         data
 
# create symlink to mounted data
ln -s /media/nas/nextcloud-data/data data

Auto Mounting nextcloud-data on Startup

Place following line into /etc/fstab.

# nextcloud data directory on Synology NAS
//NAS/nextcloud-data /media/nas/nextcloud-data cifs rw,username=admin,password=*****,uid=33,forceuid,gid=33,forcegid,addr=NAS_IP,file_mode=0640,dir_mode=0770,x-systemd.automount 0 0

• Manually mount fstab mounts with sudo mount -a.
• The x-systemd.automount will wait until the network is available before trying to establish the mount

Remounting nextcloud-data on Restart

If the server restarts, the mount point is lost. Therefore you can

• add cronjob to remount fstab with crontab -e every hour

# At minute 0 past every 3rd hour, remount drives just in case of outage
0 */1 * * * mount -a
