Upgrade from 1.8.2 to 2.0.3 stalled

Hi,

I've been trying to upgrade Airtime manually from 1.8.2 to 2.0.x for a few months and have had various problems. We recently bought a new hard drive to backup and perform the upgrade on the 350GB archive and I copied all the data across with rsync. Then I imported the database following the instructions here.

Then I copied across the config files in /etc/airtime as the api_key was different.

Then I followed the instructions here to upgrade to Airtime 2.0.x

The upgrade process starts but stalls at the point of reorganising the archive:

* Inserting stor directory location /srv/airtime/stor/ into music_dirs table
Creating media-monitor log file
Reorganizing files in stor directory

If I run ls -l /srv/airtime/stor | tail, I get:

drwxr-sr-x 2 www-data 4096 2012-03-21 18:00 fe9
drwxr-sr-x 2 www-data 4096 2011-08-30 20:38 fea
drwxr-sr-x 2 www-data 4096 2011-10-05 00:00 fec
drwxr-sr-x 2 www-data 4096 2011-09-01 02:00 fef
drwxr-sr-x 2 www-data 4096 2011-12-16 18:00 ff0
drwxr-sr-x 2 www-data 4096 2011-09-28 21:00 ff3
drwxr-sr-x 2 www-data 4096 2011-11-04 02:00 ff5
drwxr-sr-x 2 www-data 4096 2012-04-05 13:00 ffd
drwxr-sr-x 2 www-data 4096 2011-11-19 00:00 ffe
drwxrwsrwx 2 www-data www-data 4096 2012-04-26 01:30 organize

So the upgrade process has created the 'organize' directory, but in previous attempts there were also 'imported' and 'recorded' directories. There are no files in the 'organize' directory and the upgrade process has been running for 8 hours!!

The first time I attempted the upgrade, the /srv/airtime directory was a symlink and it stalled. In the current upgrade situation, airtime is running in a VM with a 450GB hard drive so I can eliminate the symlink issue but the result is the same. The VM's hard drive is at 84% with 54GB free - this should be enough space to reorganise the archive right?

How can I get airtime to complete the upgrade?

thanks

James
