The daemon "communicates" with the LDAP to let other processes know its current state. The important attributes therefore are sstProvisioningMode and sstProvisioningState in the given Backup-Account entry. The sequence is defined for adding, modifying or deleting an entry. The preconditions for all three modi are:

• sstProvisioningMode is set to add, modify or delete
• sstProvisioningState is set to 0
• sstProvisioningDate is set to 0 or the current date (format: YYYYMMDD)

Add

Precondition

...
sstProvisioningMode: add
sstProvisioningState: 0
sstProvisioningDate: 0
...

Step 1

...
sstProvisioningMode: adding
sstProvisioningState: 0
sstProvisioningDate: 0
...

Now the prov-backup-rsnapshot daemon works on the given entry.

Step 2

As soon as the prov-backup-rsnapshot daemon finished working on the given entry:

...
sstProvisioningMode: added
sstProvisioningState: YYYYMMDDThhmmssZ
sstProvisioningDate: 0
...

Modify

Precondition

...
sstProvisioningMode: modify
sstProvisioningState: 0
sstProvisioningDate: 0
...

Step 1

...
sstProvisioningMode: modifying
sstProvisioningState: 0
sstProvisioningDate: 0
...

Now the prov-backup-rsnapshot daemon works on the given entry.

Step 2

As soon as the prov-backup-rsnapshot daemon has finished working on the given entry:

...
sstProvisioningMode: modified
sstProvisioningState: YYYYMMDDThhmmssZ
sstProvisioningDate: 0
...

Delete

Precondition

...
sstIsActive: FALSE
sstProvisioningMode: delete
sstProvisioningState: 0
sstProvisioningDate: 0
...

Step 1

...
sstProvisioningMode: deleting
sstProvisioningState: 0
sstProvisioningDate: 0
...

Now the prov-backup-rsnapshot daemon works on the given entry.

Step 2

As soon as the prov-backup-rsnapshot daemon finished working on the given entry:

...
sstProvisioningMode: deleted
sstProvisioningState: YYYYMMDDThhmmssZ
sstProvisioningDate: 0
...

Exit Codes

The following list defines the return codes and their meaning for the ...:

use constant

    UNDEFINED_ERROR                         => 1,
    USER_NOT_PRESENT_IN_BACKEND             => 2,
    PERL_VERSION_NOT_STATISFIED             => 3,

    CANNOT_SET_QUOTA                        => 6,
    CANNOT_CREATE_RSNAPSHOT_CONFIGURATION   => 7,
};

Requirements

A working test server set up following the stoney backup: Server set-up guide.

Test the daemon

• The daemon is running on the Backup-Server VM (kvm-0036)
  • Open a terminal and login to the Backup-Server VM

  • tail -f /var/log/syslog/provisioning.log

• Open a second terminal and login to the Backup-Server VM
  • Make sure the directory /root/data exists, if not create it
  • Create an online backup account by executing the test script:

  • /usr/libexec/createBackupDirectory.sh --uid 3724300

  • The test script currently supports the following options:
    • --uid <UID>: Mandatory option, the backup accounts uid
    • --reseller <UID>: Optional, sets sstBelongsToResellerUID (default 4000000)
    • --customer <UID>: Optional, sets sstBelongsToCustomerUID (default 4000001)
    • --people <UID>: Optional, sets sstBelongsToPersonUID (default 4000002)
    • --givenname <Name>: Optional, sets the givenname attribute (default "Givenname")
    • --surname <Name>: Optional, sets the sn attribute (defualt "Surname")
  • Load the generated LDIF (you find them under /root/data) step by step into the LDAP and observe what the deamon is doing in the first terminal:

    • /root/loadOpenLDAPsingleLDIF.sh /root/data/01_add_3724300.ldif

    • /root/loadOpenLDAPsingleLDIF.sh /root/data/02_modify_3724300.ldif

    • /root/loadOpenLDAPsingleLDIF.sh /root/data/03_delete_3724300.ldif

    • /root/loadOpenLDAPsingleLDIF.sh /root/data/04_remove_3724300.ldif
