[NextCloudPi] moving data directory

donutlover · October 18, 2017, 9:40am

Will NCP’s “data directory” command actually MOVE an existing data directory, or will it simply change the original default location to a new place (i.e., a “one time only” operation)? My storage location is on an external USB flash drive, which is beginning to show signs of failure, so I need to move everything to a new drive ASAP.

Answer: Yes. Yes, it does move the datadir from wherever it is to a new place.

In the absence of any responses, I held my breath and did the deed. Happy to report success. Now to contact Lexar and see if they will honor their warranty…

Good for you.

I have been away for several days…

Actually the feature copies the data, as you can see here

github.com

nextcloud/nextcloudpi/blob/master/etc/nextcloudpi-config.d/nc-datadir.sh#L63


}


local BASEDIR=$( dirname "$DATADIR_" )


[ -d "$BASEDIR" ] || { echo "$BASEDIR does not exist"; return 1; }


grep -q -e ext -e btrfs <( stat -fc%T "$BASEDIR" ) || { echo -e "Only ext/btrfs filesystems can hold the data directory"; return 1; }


sudo -u www-data test -x "$BASEDIR" || { echo -e "ERROR: the user www-data does not have access permissions over $BASEDIR"; return 1; }


[[ $( stat -fc%d / ) == $( stat -fc%d "$BASEDIR" ) ]] && {
  echo "Refusing to move to the SD card. Abort"
  return 1
}


## COPY
cd /var/www/nextcloud
sudo -u www-data php occ maintenance:mode --on


echo "moving data dir from $SRCDIR to $DATADIR_..."

Is NC-Datadir still a thing? Can’t find it in the menu…

You will find nc-datadir in ncp-config or ncp-web under CONFIG

Thank you! I noticed that the config it’s a bit limited in the docker-container - in which I operate right now. Any way to change it within the docker container? I imported a backup where it was at /media/USBdrive/ncdata previously.
I mean I could direct the /media/USBdrive/ncdata to my physical drive when I start the docker image, but it just looks weird when I see it in the web-interface…

Sorry, had not realized you’re using docker.
Still, you can mount it with the -v volume option, when creating the container, as in wiki example and use:

-v /media/USBdrive/ncdata:/data

When creating and then: Either import the db or re-create the same users and run nc-scan to rebuild db.
