okay, figure out what was the problem... My partition table was
invalid :/
this maybe be a real problem as the script start by checking the disk
structure.
here are the steps:
Starting setup-storage 1.1.1+exp
Using config file: /mnt/disk_config/BACKUP
Executing: parted -s /dev/sda unit TiB print
Command parted -s /dev/sda unit TiB print had exit code 1
Executing: parted -s /dev/sda unit B print free
Command parted -s /dev/sda unit B print free had exit code 1
Executing: parted -s /dev/sda unit chs print free
Command parted -s /dev/sda unit chs print free had exit code 1
Use of uninitialized value in numeric eq (==)
at /usr/share/fai/setup-storage//Volumes.pm line 282.
Use of uninitialized value in numeric gt (>)
at /usr/share/fai/setup-storage//Volumes.pm line 284.
Invalid end byte
Error in task partition. Traceback: task_error task_partition task
task_install task task_action task main
FATAL ERROR. Installation stopped.
