CAM drive showing but no MUSIC?

[nickjupp]

Hi, I have a new clean install I can see and access the CAM drive from my macbook, but there is no MUSIC drive

running diagnostics I get

no music disk image found

it reports no music disk image found

snip from config - I have tried without quotes (6G rather than "6G") as well as percentage

#   * MUSIC_SIZE should be large enough to hold your music library, obviously.
#   * If no music size is specified, no music drive will be created.
export CAM_SIZE="30G"
export MUSIC_SIZE="6G"

from the logs I see Fri 26 Feb 11:14:33 GMT 2021 : create-backingfiles: cam: 30G, music: 0, mountpoint: /backingfiles

and there is no music mountpoint or music_disk.bin

root@teslausb:~# cd /mnt
root@teslausb:/mnt# ls
cam
root@teslausb:/mnt# cd /backingfiles/
root@teslausb:/backingfiles# ls
cam_disk.bin  snapshots

so not sure why it's not picking up the 6G from the MUSIC_SIZE variable?

any advice please?

thanks Nick

Did you initially not specify a music size and then add one later and rerun setup?

[marcone]

Per discussion in the Discord, this happened because no music size was specified initially, and when rerunning setup teslausb doesn't update the image(s). I will either put a note to that effect in the config file, or make setup more robust.

[nickjupp]

Thanks for your help. can confirm music_disk.bin is there now after deleting cam_disk.bin and re-running setup

Thanks for this. I was wondering how to resize the music_disk.bin after I initially sized it as 4G and now would like to expand it to 16G.

To piggyback off this thread, I'm experiencing a similar issue. Music drive just won't be created (missing music_disk.bin). I've even deleted the cam_disk.bin and reran the setup, but I get the same results. Setup logs show it sees the music size but won't create:

Here is my config file (all commented out lines have been removed):

export ARCHIVE_SYSTEM=cifs
export ARCHIVE_SERVER=192.168.1.x
export SHARE_NAME=NAS2/Cam/Tesla
export SHARE_USER=redacted
export SHARE_PASSWORD=redacted
export CIFS_VERSION="3.0"
export CAM_SIZE=52G
export MUSIC_SIZE=4G
export MUSIC_SHARE_NAME=Backup/CarMP3/Tesla
export SSID="redacted"
export WIFIPASS="redacted"
export TIME_ZONE="America/Los_Angeles"
export TESLAUSB_HOSTNAME=teslausb-ModelY

Any idea where to start? It's a 64Gig SD card, so there should be plenty of space for both partitions. The Cam drive otherwise works great in the car. I simply noticed shortly after installing my music wasn't there. Took me by surprise as I've been running another Pi Zero W with this system for over 4 years now in my Model 3 with no issues.

[marcone]

@chrisalmy 64 GB is the bare minimum that will work. I highly recommend using a 128 or 256 GB sd card instead. I suspect the problem in your case is that you specified CAM_SIZE=52G, and after accounting for OS overhead that doesn't leave enough space for the 4GB music drive. Try reducing CAM_SIZE to 40G or so (you will need to reflash the sd card and start over, or delete the existing /backingfiles/cam_disk.bin and rerun setup)

[chrisalmy]

@marcone Yep, that appears to be the issue. I would have thought 8Gigs of space would be more then enough for the OS, but I was wrong. I thought my existing 4+ year old TeslaUSB setup with 64Gig SD card also had about 52Gig of CAM partition, but I just pulled it up and sure enough, it was 42Gig. I reduced the CAM size and I now have a music folder!

Now on to the next issue. While on a short road trip a few days ago, the drive stopped working a few times and needed a reboot. The car also said the drive was too slow (a message I haven't seen in years). This could be because my new Model Y is a AP4 system which saves about 180MB of data per minute versus my AP3 which does about 105MB per minute. I'll keep monitoring the setup, as for all I know the poor Zero W may not be able to keep up. If I continue to have issues, I have a spare Pi 4 I can try instead.

I tried to define export MUSIC_SHARE_NAME with "Music", "backup:Music" etc. without success. cam is working fine, how to define music using rclone? (I assume its a syntax issue...) thanks a lot!

Music syncing is only supported for CIFS, not for rsync and rclone. You can still have a music drive, you'll just have to copy to it manually.
