Hi All,

I'm having problems with the scheduling of jobs. We have a setup with a tape robot with 2 drives and currently about 200 servers to backup. We make a backup of a server to disk. The next day it is copied to Tape with a copy job. To make optimal use of the tapedrives, we created 14 disk pools (2 for every day) and 28 schedules (4 for every day: 2 disk pools and 2 per disk pool to devide the full backups better).

The problem occurs when  there is a Full backup of a servers which has a lot of data. The job runs for more then an hour. The jobs in the same schedule are run concurrent (set to 12). But when the next schedule starts, those jobs wait on the large job to be finished with the message waiting on Storage.

When issueing the command 'echo "status stor" | bconsole' the next thing caught our attention:

Jobs waiting to reserve a drive:
   3608 JobId=166029 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166033 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166035 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166037 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166041 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166043 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166044 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166045 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166053 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166056 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).
   3608 JobId=166057 wants Pool="Disk_wed_2-Pool" but have Pool="" nreserve=0 on drive "diskbackup_wed_2" (/bacula/wednesday/diskbackup_wed_2).

The jobs have no pool.

Does anyone know how to solve this?
