Hat man ein Synology-NAS-System mit einem Atom oder anderen Intel Prozessor so kann man dort des Sesam Client installieren.

Sesam Client auf einem Synology NAS

Problem: Queues sind nicht vorhanden, Meldung: A queue with that name does not exist

sm_config_drives

Client-Seup Leider wird von den Sesam-Setup-Programmen der Server nicht berechtigt auf den Client zuzugreifen und wenn man SSH nutzen möchte wird der Server-Key nicht übertragen. Der folgende Befehl schreibt alle nötige in die sm_ctrld.auth und überträgt den SSH-Publc-Key des Servers in die „authorized_keys“ des Clients.

/opt/sesam/bin/sesam/sm_setup set_client <server-hostname>

Problem: Datastore enthält mehr Safesets als in der Datenbank verzeichnet sind.

# prüfen (3 = Laufwerk)
sm_data_store check_db -d 3
# überflüssige löschen (3 = Laufwerk)
sm_data_store check_db -d 3 -o remove_ds

GUI-Client authorisieren

sm_setup allow_gui -u 'benutzername' -c 'adminpc'

oder ohne Einschränkung

sm_setup allow_gui -u '*' -c '*' -m admin

09/2011: Datenbankabfrage angepasst: kunde → customer für Sesam >= 4
02/2012: notify und alarm unterscheidbar gemacht.
02/2012: notify erweitert, so, dass GET_VOLUME Mails nicht unkontrolliert versandt werden sondern nur alle „DELAY“ Minuten

Unter Konfiguration → Support → e-Mail-Einstellungen mache ich Einträge mit den Account Namen:

• sm_notify
• sm_alarm
• sm_disaster

und trage immer auch den Kunden ein. Damit kann man dann für alle drei Scripte getrennte Einstellungen machen und weiss von welchem Kunden bzw. Servere die Mail kommt da das Subject dann so aussieht: „Kunde / Sesam: …“. Die angepassten Sctipte sehen dann wie folgt aus:

# Description : 
#    This procedure is called from a SESAM backup if job name contains string
#    "DISASTER" or "SESAM", e.g. "SESAM_BACKUP".
#
#    These backups should be designed to save files, which are needed to recover
#    the SESAM server itself - called disaster recovery.
#    These are the .\sesam\... directory and the LIS-directory, if it is not 
#    under .\sesam\..  .
#    Furtheron the files of the database.
#
#    SESAM sends the media label and the barcode of the used media and 
#    a valid restore command to this procedure.
#    Starting this command, the file of the currently running backup will be
#    copied back to their original places.
#
#    It is urgently recommended to sent it to several different locations to
#    keep them available in case of full crash of the SESAM server itself.
#
#    For example write them to files on other computers within your net, 
#    mail them etc. .
#                     
#      The values are as follows:
#
#         $1 = {label} {backup source} {barcode}
#         $2 = {sbc restore command}
#
#    There is already an example configured below. This works if in Sesam GUI
#    in menu line "Configratione/ Support / E-Mail-Settings" the account "sesam"
#    had been added.
#
#    It is easy to do user specified adaptations !!!
#
# ******************************************************************************
#
# Beschreibung 
#    Wird vom SESAM waehrend einer Sicherung gerufen, deren Name "DISASTER"
#    oder "SESAM" beinhaltet z.B. "SESAM_BACKUP".
#
#    Diese Sicherungen sollten Verzeichnisse kopieren, die fuer die Wieder-
#    herstellung des SESAM Servers selbst noetig sind, dem sogenannten 
#    Disaster Recovery.
#
#    Dieses sind das .\sesam\... Verzeichnis, sowie LIS-Verzeichnis, falls
#    sie nicht unter .\sesam liegen.
#    Desweiteren die Dateien der SESAM Datenbank.
#
#    SESAM sendet den Medienlabel und ggf. den Barcode des benutzten Mediums
#    und ein vollstaendiges Restaurierungskommando an diese Prozedur.
#    Startet man diese Prozedur von der Komandozeile, so werden alle Dateien 
#    der gelaufenen Sicherung wieder an ihre urspruenglichen Plaetze zurueckkopiert.
#               
#    Es wird dringendst empfohlen diese Werte in Dateien, Mails etc. auf mehrere
#    andere Rechner in ihrem Netz zu verlagern, um sie im Falle eines 
#    Systemausfalls des SESAM Servers verfuegbar zu haben.
#
#       Die Werte sind die folgenden:
#
#         $1 = {label} {backup source} {barcode}
#         $2 = {sbc restore command}
# 
#    Unten ist bereits ein Beispiel eingerichtet, bei dem im Vorfeld in der 
#    Sesam GUI im Menue unter "Konfiguration/ Support/ e-Mail-Einstellungen"
#    der Account "sesam" anzulegeni ist.
#
#    User-spezische Anpassungen sind damit leicht durchfuehrbar !!!

# OR via SMTP interface with configured email account "sesam" in Sesam GUI
sm_smtp -A "sm_disaster" -s "$customer / SEP Sesam INFO: SEP sesam Notfall-Informationen" -M "${gv_rw_work}/disaster.tmp"

An den Anfang eines jeden Scripts gehört das hier:

if [ ! -f /etc/sesam2000.ini ]; then
    echo "ERROR: /etc/sesam2000.ini missing !"
    exit 1
fi

Um sicher zu stellen dass das Script nur ausgeführt wrid, wenn die Ini auch existiert.

Es sieht such aus als wäre das Init-Script von einem Suse/Red Har Script abgeleitet. Dort gibt es nämlich eine Init-Funktionssammlung die eine Funktione „init_failed“ beinhaltet. Das gibt es aber unter Debian nicht. Mutmassung: Damit das Sctip so änlich aussieht hat SEP aus dem Funktionsaufruf einfach eine Variable gemacht und die im Vorfeld auf „3“ gesetzt. Im Original sieht das so aus:

... | rc_failed

Und im Debian-Initecritp:

... | exit $rc_failed

Das hat zur Folge, das man nie weiss wenn man das Init-Script benutzt ob der Auftruf nun erfolgreich war oder nicht.

Um das zu zu korrigieren füge ich dem Script die Funktion „rc_failed“ in abgewandelter From hinzu:

function rc_failed ()
{
  echo " FAILED"
  exit $rc_failed    
}

und ändere alle Zeilen die so ausehen:

${GV_RO_BIN}/sm_startup >/dev/null 2>&1 || exit $rc_failed

in das hier:

${GV_RO_BIN}/sm_startup >/dev/null 2>&1 || rc_failed

Nach noch ein paar anderen Schönheitsoperationen sieht das dann so aus:
