NCP: cannot move datadir

I have a fresh install of NCP on Raspberry Pi, updated to latest versions. I have an external SSD attached, and was able to move database and swap to the SSD. But not the datadir. I did create the ncdata directory, so it exists.

Running nc-datadir
Nextcloud is in maintenance mode - no apps have been loaded

INFO: /media/MX500/ncdata is not empty. Creating backup /media/MX500/ncdata-09-11-19

cp: cannot create directory ‘’: No such file or directory
Done. Press any key…

What should I do?

the same here

I finally managed to move the datadir to the USB disk. I found instructions on how to do it manually here: https://pimylifeup.com/raspberry-pi-nextcloud-server/ “Moving Nextcloud’s data folder”.
I also needed to run nc-fix-permissions.

Thanks for reporting your issue is fixed.

same problem here
brand new pi 4,
nothing else installed
fixed ip adress
apt-get update and upgrade and used this nextcloudpi config:
wget https://raw.githubusercontent.com/nextcloud/nextcloudpi/master/install.sh
sudo bash install.sh

error the same after setup and wizzard for nc-datadir.
no such file or directory .

OK,
i started from scratch, with

  1. buster lite,

  2. apt-get update/upgrade

  3. password change of pi user

  4. sudo bash

  5. raspberrypi installation script ```
    curl -sSL https://raw.githubusercontent.com/nextcloud/nextcloudpi/master/install.sh | bash

  6. after setup, wizard start for change of data directory to usb storage:
    [ nc-automount ]
    Created symlink /etc/systemd/system/multi-user.target.wants/nc-automount.service → /usr/lib/systemd/system/nc-automount.service.

ls -l /media gives me

drwxr-xr-x 1 root root 0 Sep 13 12:29 myCloudDrive
lrwxrwxrwx 1 root root 19 Sep 13 12:29 USBdrive -> /media/myCloudDrive

so Link is /media/USBdrive
to Device /media/myCloudDrive
as it was formated to btrfs from [ nc-format-USB ]

the chmod looks good right? read write access for root

if found that discussion on githup from 2017 (quite old I know):

there someone has the same strange behaviour
I’ve tried almost everything from nachoparker with removed media symlinks,
changed devicenames
and especially wayneouttheres description of his fix: https://github.com/nextcloud/nextcloudpi/issues/305#issuecomment-377697798

but when I switch to ncp control panel to use nc-datadir with the Data directory:
/media/myCloudDrive/ncdata

it gives:
[ nc-datadir ]
Nextcloud is in maintenance mode - no apps have been loaded

so after some more investigation.
the nc-datadir.sh fails at line 74 or below when the btrfs subvolumes should be used.

  mkdir -p "$DATADIR"
  DATADIR=$(cd "$DATADIR" && pwd -P)

what is wrong with my automount? or btfrs subvolumes?
what I’m doing wrong in this easy setup?
I’m running a nextcloud instance on an vps server since two years without a flaw, but I fail to scan this raspberrypi-nextcloud .sh scripts … I’m lost… any help is highly welcome…

Hi,

Your last issue seems like a mistake with the fail2ban fix. Can you try sudo ncp-update devel and let me know if it works for you after that?

Hi nachoparker,
first of all, thanks for your fast reply.
tried the development branche and that solved the problem.
datadir and database could be moved without a problem.

just for the sake of learning: can you point me to the problem in the actual ncp version? what script fails, why is it the fail2ban fix? that is not even close to what i thought about the btrfs subvolume mounting point or the nc-datadir.sh lines i’ve highlighted above.

greetings

I moved the point where the directory is created, but didn’t realize that in the BTRFS case it assumes that it doesn’t exist, so the btrfs command fails
