Cover art not displaying. Unable to create thumbnail.

[samoshit]

Subsonic accesses my music through a read-only fileshare. I'd prefer it if I can store thumbnails in /var/subsonic/thumbnails, rather than the directory of the track being played. Can this be done?

[sindre_mehus]

The thumbnails (scaled-down version of the cover art images) are indeed stored in /var/subsonic/thumbs. The cover art images themselves, however, are stored together with the music. There is no way around this, I'm afraid.

[samoshit]

tomcat has full write access to the thumbs dir

Code: Select all

sean@santo:/var/subsonic$ ls -ld thumbs
drwxr-xr-x 3 tomcat tomcat 4096 2007-07-13 09:34 thumbs/

the cover art is already within the album directory. they are all named windows style - folder.jpg. i have cover art in this form with about 90% of my albums.

why does tomcat need to write to the album dir?

[sindre_mehus]

Hm, I see. No, Subsonic shouldn't need write access to the album directory. Can you pls give some more details about the error you get?

Can you also double-check that Tomcat is running as user tomcat?

[samoshit]

Whats a line of code that will prove Tomcat is running as tomcat? I use Tomcat5.sh as a startup script, and I told it to user tomcat as the user when running.

Code: Select all

JAVA_HOME=/usr/lib/jre1.6.0_01/
CATALINA_HOME=/usr/share/tomcat/
DAEMON_HOME=/usr/share/tomcat/
TOMCAT_USER=tomcat

here is a tail of subsonic.log. It seems more detailed than the "Help" button shows.

oh, and i should also inform you of how the music is accessed.

My music is stored in a locked directory, accessible only by FTP program and FTP users. I don't trust my shell users to enter this area. If I could, I'd host on 2 boxes, but this is more simple.

The FTP directory is then mounted read-only using --bind to a directory subsonic can access.

Code: Select all

sean@santo:/var/subsonic/music$ mount | grep subsonic
/jail/glftpd/site/mp3 on /var/subsonic/music type none (ro,bind)
/jail/glftpd/site/mvid on /var/subsonic/music/videos type none (ro,bind)

Even though it is mounted read-only, the attributes show something different. Perhaps this is causing errors.

Apparently the tomcat user is missing write access to the temp directory. This is most likely /tmp or /var/tmp.

not sure why. i found two temp dirs matching *tomcat* and tomcat user has write access to both.

I'm not on Linux, so I'm not sure how Tomcat is installed there, but is there a directory called "temp" or "tmp" somewhere in the TOMCAT_HOME directory? (Where subsonic.war is deployed)

[samoshit]

Yes there is but it is a symlink back to /var/tmp/tomcat. As you can see it is chmod 777 so it has full read/write.

Code: Select all

sean@santo:/usr/share/tomcat$ ls -l temp
lrwxrwxrwx 1 root root 23 2007-07-12 20:16 temp -> ../../../var/tmp/tomcat/
