USB Hard Drive reported size problem

bnilsson

I have a HiFiBerry RP3 running RuneAudio 20160313beta.

There seems to be a long time problem that the smb guest connection to "MusicStore" share reports the remaining size of the SD card as the available size, and not the actual size of any USB connected Hard Drive.
This means if I have a few hundred MB left on the SD, and I connect a 1TB USB HD I cannot use the smb share connection to copy files to the USB HD. "No available space on drive".
Files can be copied one by one if each is less than the SD space, but if the track is really big, it is impossible.

I think the RuneAudio built-in smb share "MusicStore" would be the perfect way to maintain the music library, if it was not for this issue.

Any news on a built-in RuneAudio solution to this problem?

Hi bnilsson,

Yes, you have to change the samba configuration files on your Pi.
- get access to your Pi
- modify /etc/samba/smb.conf

#======================= Global Settings =======================

[global]

   workgroup = WORKGROUP
   server string = RuneAudio Player
   dns proxy = no
   log level = 0
   syslog = 0
   guest account = root
   map to guest = bad user
   load printers = no
   printing = bsd
   printcap name = /dev/null
   disable spoolss = yes
   domain master = no
   local master = no
   preferred master = no

#======================= Share Definitions =======================

   directory mask = 0775
   create mask = 0775

[MusicStoreNAS]
   comment = MPD MusicStore (/mnt/MPD/NAS)
   path = /mnt/MPD/NAS
   read only = no
   public = yes
   follow symlinks = yes
   wide links = yes
[MusicStoreUSB]
   comment = MPD MusicStore (/mnt/MPD/USB)
   path = /mnt/MPD/USB
   read only = no
   public = yes
   follow symlinks = yes
   wide links = yes
[MusicStoreLocalStorage]
   comment = MPD MusicStore (/mnt/MPD/LocalStorage)
   path = /mnt/MPD/LocalStorage
   read only = no
   public = yes
   follow symlinks = yes
   wide links = yes

- reboot
- check your network connections on your PC

You have to connect directly to your USB storage device not to the music store!

- Get access to the console:
Use SSH from your PC

If you are not familiar with SSH read this for Windows or this for Linux/MacOS
The default login for RuneAudio is "root" with the password "rune" (without quotes).

Or use WinSCP to acces the filesystem on your device. It is highly recommended to use Notepad++ for editing files.

Looks promising.

Strangely enough, my USB disk gets mounted RO. Normal?
Before the smb.conf change I somehow got it mounted RO first, then it became RW for unknown reasons.
That's how I could test the file size behavior.
I don't feel I am in complete control here.
Any advice?

Sorry I diffuse out of topic...

Hi bnilsson,

please check the mount options in /etc/udevil/udevil.conf.
Depending on the filesystem used on your thumb drive it may be set to RO.

# default_options specifies what options are always included when performing
# a mount, in addition to any options the user may specify.
# Note:  When a device is present in /etc/fstab, and the user does not specify
# a mount point, the device is mounted with normal user permissions using
# the fstab entry, without these options.
# default_options_FSTYPE, if present, is used to override default_options
# when mounting a specific fstype (eg ext2, nfs).
# The variables $USER, $UID, and $GID are changed to the user's username, UID,
# and GID.
# FOR GOOD SECURITY, default_options SHOULD ALWAYS INCLUDE: nosuid,noexec,nodev
# WARNING:  OPTIONS PRESENT OR MISSING CAN CAUSE SERIOUS SECURITY PROBLEMS.
default_options           = nosuid, noexec, nodev, noatime
default_options_file      = nosuid, noexec, nodev, noatime, uid=$UID, gid=$GID, rw
# mount iso9660 with 'ro' to prevent mount read-only warning
default_options_iso9660   = nosuid, noexec, nodev, noatime, uid=$UID, gid=$GID, rw, utf8
default_options_udf       = nosuid, noexec, nodev, noatime, uid=$UID, gid=$GID
default_options_vfat      = rw, iocharset=utf8, noatime, uid=$UID, gid=$GID
default_options_exfat     = rw, nonempty, uid=$UID, gid=$GID
default_options_hfsplus   = rw, uid=$UID, gid=$GID
default_options_msdos     = nosuid, noexec, nodev, noatime, fmask=0133, dmask=0022, uid=$UID, gid=$GID
default_options_umsdos    = nosuid, noexec, nodev, noatime, fmask=0133, dmask=0022, uid=$UID, gid=$GID
default_options_ntfs      = nosuid, noexec, nodev, noatime, fmask=0133, uid=$UID, gid=$GID, utf8
default_options_cifs      = nosuid, noexec, nodev, uid=$UID, gid=$GID
default_options_smbfs     = nosuid, noexec, nodev, uid=$UID, gid=$GID
default_options_sshfs     = nosuid, noexec, nodev, noatime, uid=$UID, gid=$GID, nonempty, allow_other
default_options_curlftpfs = nosuid, noexec, nodev, noatime, uid=$UID, gid=$GID, nonempty, allow_other
default_options_ftpfs     = nosuid, noexec, nodev, noatime, uid=$UID, gid=$GID
default_options_davfs     = nosuid, noexec, nodev, uid=$UID, gid=$GID
default_options_tmpfs     = nosuid, noexec, nodev, noatime, uid=$UID, gid=$GID
default_options_ramfs     = nosuid, noexec, nodev, noatime, uid=$UID, gid=$GID

The next version will have all these changes by default.

I replaced /etc/udevil/udevil.conf with the content you supplied and rebooted.

Now it gets really strange.

My 160GB USB disk is labelled "MUSIC".
In RuneUI the disk is reported mounted on /dev/disk2 USB/MUSIC.
RuneUI/Library shows "USB storage(3)", opening this entry shows nothing.
In the ssh terminal, the command "mount" does not report any /dev/disk2 mounted.
The smb share MusicStoreUSB still reports the small SD remaining space.
If I copy a small music file into MusicStoreUSB/MUSIC, the USB disk activity light remains inactive.
Dismounting the USB disk and connecting it to my Mac reveals an empty disk!
And /mnt/MPD/USB/MUSIC still contains the file I copied.

Apparently, the disk mount is "a fake", the disk is not mounted at all.
/mnt/MPD/USB/MISIC is using the DS memory space?

bnilsson

Sorry, I realize now that your udevil.conf was not intended to be the complete file.
I applied your changes to the existing udevilconf and now the disk gets mounted rw, and the behavior is normal.
However, in the smb share "MusicStoreUSB" the MUSIC folder is marked no access.
I have formatted the disk Fat32.

bnilsson

I formatted the disk as HFS+ and now looks accessible in the MusicStoreUSB share,
But it is still mounted ro...

However, the available space in the smb share is still that of the SD card, 175MB.

If I change the share path from

[MusicStoreUSB]
path = /mnt/MPD/USB
to
[MusicStoreUSB]
path = /mnt/MPD/USB/MUSIC

I get the correct size, 160GB.

So this issue is sort of "partially solved", but this is not a flexible solution in this form.
The smb share path MUST be set to the device mount point itself(mnt/MPD/USB/MUSIC), not to the folder above it (mnt/MPD/USB):

[root@runeaudio samba]# mount:
/dev/sda2 on /mnt/MPD/USB/MUSIC type hfsplus (ro,nosuid,nodev,noexec,noatime,umask=22,uid=1000,gid=92,nls=utf8)

My remaining problem is now how to mount the USB drive RW mode.

bnilsson

Reformatted the disk to FAT32 again on my Mac, connected it to the Hifiberry, now all works.
Size reported for the USB smb share is 160GB as it should.
I can copy files of any size.

The only issue is the "fixed" configuration regarding the disk path name.
The smb share path must be directed to the disk mount point itself, not to the parent USB folder.
The parent USB folder belongs to the SD file system, hence the small size limit.

So the issue is partially SOLVED.

(But why is a hfsplus formatted disk still mounted RO?)

Thanks for the support, the solution is now workable.

Finally, I decided to use this /etc/samba/smb.conf:

#======================= Global Settings =======================

[global]

   workgroup = WORKGROUP
   server string = RuneAudio Player
   dns proxy = no
   log level = 0
   syslog = 0
   guest account = root
   map to guest = bad user
   load printers = no
   printing = bsd
   printcap name = /dev/null
   disable spoolss = yes
   domain master = no
   local master = no
   preferred master = no

#======================= Share Definitions =======================

   directory mask = 0775
   create mask = 0775

[MusicStore]
   comment = MPD MusicStore (/mnt/MPD/LocalStorage)
   path = /mnt/MPD
   read only = no
   public = yes
   follow symlinks = yes
   wide links = yes

[MusicStore DISK]
   comment = MPD MusicStore (/mnt/MPD/USB/DISK)
   path = /mnt/MPD/USB/DISK
   read only = no
   public = yes
   follow symlinks = yes
   wide links = yes

This gives me the same functionality as the default setup, plus direct access to the external disk file system.
The only drawback is that the mount point path in the smb.conf must correspond to the name of the disk.
For this smb.conf, my external USB disk must be formatted with the name label "DISK" to be visible as a mountable smb share.
Unless disks are changed often, this is not a big problem.
