; Das Szenario: Es wird bei einer Maschine ein Spiegel vom Massenspeicher verwendet. Bei der Installation von [[TrueOS]] ist das ganz einfach auswählbar. [[TrueOS]] richtet das auch alles ein. (Aber was passiert da eigentlich?) Ferner geht es um das Nachvollziehen der durch <code>pc-sysinstall</code> durchgeführten Abläufe. Aber auch notwendige Wartungsarbeiten - etwa das [[#Ersetzen von einem Massenspeicher als Teil von einem mirror]], sollen so "sauber" erledigt werden können.

WIP
; Szenario:
* Eines der Geräte für Massenspeicher ist ausgefallen und muss ersetzt werden.
*: Zum Testen dieses Szenario wurde TrueOS mit einem Spiegel für den Massenspeicher installiert.
*:: Theoretisch (und praktisch) funktioniert das auch bei einer standardmäßigen Installation von FreeBSD mit einem Spiegel für den Massenspeicher.
*: Zum Testen wurde eines der Geräte für Massenspeicher einfach entfernt. (Es soll praktisch dargestellt werden, dass das Gerät für Massenspeicher "kaputt" wäre.)
*: Zum Testen gibt es gleichwertiges Gerät für Massenspeicher, dass als Ersatz dienten soll.

Make sure to wait until resilver is done before rebooting.
If you boot from pool 'vzfspool', you may need to update
boot code on newly attached disk '/dev/ada0p2.eli'.
Assuming you use GPT partitioning and 'da0' is your new boot disk
you may use the following command:
        gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0

mirroring[Bearbeiten]


Das Szenario


Es wird bei einer Maschine ein Spiegel vom Massenspeicher verwendet. Bei der Installation von TrueOS ist das ganz einfach auswählbar. TrueOS richtet das auch alles ein. (Aber was passiert da eigentlich?) Ferner geht es um das Nachvollziehen der durch pc-sysinstall durchgeführten Abläufe. Aber auch notwendige Wartungsarbeiten - etwa das #Ersetzen von einem Massenspeicher als Teil von einem mirror, sollen so "sauber" erledigt werden können.


Ersetzen von einem Massenspeicher als Teil von einem mirror[Bearbeiten]


Szenario




  • Eines der Geräte für Massenspeicher ist ausgefallen und muss ersetzt werden.

    Zum Testen dieses Szenario wurde TrueOS mit einem Spiegel für den Massenspeicher installiert.

    Theoretisch (und praktisch) funktioniert das auch bei einer standardmäßigen Installation von FreeBSD mit einem Spiegel für den Massenspeicher.
    

    Zum Testen wurde eines der Geräte für Massenspeicher einfach entfernt. (Es soll praktisch dargestellt werden, dass das Gerät für Massenspeicher "kaputt" wäre.)
    

    Zum Testen gibt es gleichwertiges Gerät für Massenspeicher, dass als Ersatz dienten soll.
