Degraded dump in amanda 3.5.2

Hi, I'm setting up a new backup server with amanda 3.5.2 on CentOS 7 
with vtapes. I've setup the vtapes directories, created the job and 
added the dlc, checked permissions, then run amcheck and it shows no 
errors. However when I run amdump, only one of the dlc gets backed up, 
the other ones give a "can't do degraded dump without holding disk" 
error. The config is:

amanda.conf

reports
dumpuser "amandabackup" # the user to run dumps under
mailto "yyyyy@xxxxx"        # space separated list of operators at your 
site

Only one of the dlc gets backed up (/usr/local/bin) even though they are 
all on the same host (the amanda server). I've tried running jobs with 
dlc on other servers and the result is the same, only one of the dlc 
gets backed up

Any idea what could be causing this?

Yours
