Issue :

Dependent row(s) ‘smb_roles.id = 1’ isn’t found for ‘smb_users.roleId = 1’
Masalahnya terjadi karena tabel smb_roles kosong

Resolution :

Dump the Plesk database and smb_roles table:
[root@Node03 ~]# MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -uadmin psa > /root/psa.`date +%Y%m%d.%H%M%S`.sql
[root@Node03 ~]# MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -uadmin psa smb_roles > /root/psa.smb_roles.`date +%Y%m%d

Add the default Plesk smb roles:
[root@Node03 ~]# MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin

MariaDB [(none)]> use psa
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
