If you did not allocate a large partition to
/home before installing YunoHost, and that your apps require a lot of spaces, you can still add an external driver after setting up your system.
Even though these steps are relatively simple, they may appear technical. In any case, they require you to take your time.
You should be connected as root on your server, for instance via SSH. (Note: being logged as
admin, you can upgrade to
root with the command
It can be useful to create a backup of your install before starting.
You should also have your external drive (plugged via USB or SATA).
Start by connecting your drive to the system. You shall then identify which name is used by the system to refer to the disk.
You can do this with this command :
It may yield something like this :
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 931.5G 0 disk └─sda1 8:1 0 931.5G 0 part mmcblk0 179:0 0 14.9G 0 disk ├─mmcblk0p1 179:1 0 47.7M 0 part /boot └─mmcblk0p2 179:2 0 14.8G 0 part /
mmcblk0 corresponds to an SD card of 16Go (the partitions
mmcblk0p2 are used as the boot partition
/boot and the system partition
/). The external drive is
sda which is about 1TB and has only one partition
sda1 which is not mounted (no "MOUNTPOINT").
On a different setup, your system partition might be
sda and so your external drive might be
sdb for instance.
This operation is optional if your disk has already been formatted.
First let's create a new partition on the disk :
then sucessfully type
w to create the new partition.
lsblk that your disk really does contain a single partition.
Before you can use your disk it has to be formatted.
You should be aware that formating a drive implies to erasing every data on it! If your disk is already "clean", you may ignore this step.
To format the partition :
mkfs.ext4 /dev/YOUR_DISK1 # then 'y' to validate
YOUR_DISK1 by the name of the first partition on the disk. Be careful not to do any mistake here, as it can mean erasing data on your main system if you are using the wrong name ! In the previous example, the name of our disk was
"Mounting" a disk corresponds to making it effectively accessible in the filesystem tree. Here, we choose the arbitrary name
/media/storage but you can choose a different name (for instance,
/media/my_disk ... ).
Let's start by creating the directory :
Then we can manually mount the disk with :
mount /dev/YOUR_DISK1 /media/storage
/dev/YOUR_DISK1 corresponds to the first partition on the disk)
Next, you should be able to create files in
/media/storage, and, for instance, add
/media/storage as an external drive in Nextcloud.
So far, we only mounted the disk manually. But it can be nice and useful to have it being mounted automatically at each boot.
Let's start by finding the UUID (universal identifier) of the disk with :
blkid | grep "/dev/YOUR_DISK1:" # Should return something like # /dev/sda1:UUID="cea0b7ae-2fbc-4f01-8884-3cb5884c8bb7" TYPE="ext4" PARTUUID="34e4b02c-02"
Let's add a line in the file
/etc/fstab which manages which disks are mounted at boot. We open this file with
And add this line :
UUID="cea0b7ae-2fbc-4f01-8884-3cb5884c8bb7" /media/storage ext4 defaults,nofail 0 0
(this line should be adapated according to previous info and choices)
Use Ctrl+X then
y to save.
You can then reboot the system to test if the disk is mounted automatically.
