External USB Drive Configuration

WROLPi expects a single USB drive to be mounted at /media/wrolpi. However, multiple drives are supported. WROLPi uses special directories to know where to place downloaded files. The config special directories cannot be changed and WROLPi will always look for it at /media/wrolpi/config

The default special directories are the following (the inputs are disabled because the "Edit Directories" toggle is not checked):

Special Directories Settings

2+ drives

As of the writing of this article, WROLPi partially supports multiple drives. The primary drive must be mounted to /media/wrolpi, the configs will be written to this drive. The other drive must be mounted within /media/wrolpi.

If you wanted your secondary drive named "secondary", you could mount it at /media/wrolpi/secondary. Linux will ensure the files are placed in the correct drives.

Migrating from one to two drives

Assuming that you have a WROLPi with a single external hard drive, and would like to add a second drive, follow these steps.

  1. Mount the secondary drive to some path in /media/wrolpi. We will assume you use /media/wrolpi/secondary for this example. Follow this pattern for all new drives.

    1. mkdir /media/wrolpi/secondary
    2. mount /dev/sdb1 /media/wrolpi/secondary

  2. Decide where WROLPi will download files.

    1. WROLPi will download videos to /media/wrolpi/videos by default. If you want WROLPi to save new videos to the secondary drive, edit the "Videos Directory" in Admin > Settings > Special Directories to something like secondary/videos.
    2. Do this for all special directories.
    3. You can keep all special directories in the primary drive, WROLPi will still search the secondary drive for any new files.

  3. Make the drive mounts permanent by modifying /etc/fstab:

    /dev/sda1 /media/wrolpi auto defaults,nofail 0 0           # primary
/dev/sdb /media/wrolpi/secondary auto defaults,nofail 0 0  # secondary

  4. Verify that the mounts are correct by rebooting.

    • sudo reboot

  5. Refresh your files

Default fstab

This is an example default fstab on a Raspberry Pi:

proc            /proc           proc    defaults          0       0
PARTUUID=4f724c6e-01  /boot/firmware  vfat    defaults          0       2
PARTUUID=4f724c6e-02  /               ext4    defaults,noatime  0       1
/dev/sda1 /media/wrolpi auto defaults,nofail 0 0
# a swapfile is not a swap partition, no line here
#   use  dphys-swapfile swap[on|off]  for that
