Script para exclusão de volumes em massa

Muitas vezes ocorre que por algum erro, o Bacula gera centenas de volumes com erros, e para excluí-los é necessário executar manualmente no bconsole um comando para excluir volume por volume.

Para facilitar e automatizar esta tarefa é possível utilizar um shell script:

Download do script

wget -c https://raw.githubusercontent.com/wanderleihuttel/bacula-utils/master/conf/scripts/_delete_multiples_volumes.sh -O /usr/local/bin/_delete_multiples_volumes.sh
chmod a+x /usr/local/bin/_delete_multiples_volumes.sh

O script

#!/bin/bash

echo ""
for volname in $(echo "list media pool=${pool}" | ${bconsole}  | grep "|" | grep -v "MediaId" | grep "${volstatus}" | cut -d "|" -f3 | sed 's/ //g'); do
    echo " ${volname}" ;
done
echo ""

if [ ${arraycount} == "0" ]; then
    echo -e "No volumes found with status '${volstatus}'n"
    echo -e "Operation aborted!n"
    exit
else
    echo -e "${arraycount} volumes was found with status '${volstatus}'n"
fi

read -p "Are you sure you want to delete all ${arraycount} volumes? This operation is irreversible! (Y-Yes / N-No) " confirm
if [ "${confirm}" == "y" ] || [ "${confirm}" == "Y" ]; then
    for volname in $(echo "list media pool=${pool}" | ${bconsole}  | grep "|" | grep -v "MediaId" | grep "${volstatus}" | cut -d "|" -f3 | sed 's/ //g'); do
        echo "delete volume=${volname} pool=${pool} yes" ;
        # Uncomment the line below to exclude the volumes in the catalog
        #echo "delete volume=${volname} pool=${pool} yes" | ${bconsole} ;

        # Uncomment the line below and change the path of storage to remove volume from the disk also
        # rm -f /path/to/storage/${volname}
    done
    echo -e "Operation finished with success!n"
else
    echo -e "Operation aborted!n"
fi

Antes de executar o script

Existem duas linhas no arquivo que por medidas de segurança estão comentadas. Então é possível executar o script sem nenhuma modificação. Então execute uma primeira vez e certifique-se que de os volumes que serão excluídos são os corretos e só depois descomente as linhas do script.
Substitua o caminho “/path/to/storage” pelo diretório físico onde estão os volumes caso para excluir os volumes do disco também (só em caso de backup em disco)

Descomentar as linhas abaixo no script
# echo "delete volume=${volname} pool=${pool} yes" | ${bconsole} ;
# rm -f /path/to/storage/${volname}
