Hintergrund
- Es kommt zu dieser Fehlermeldung, weil gpg die Passphrase nicht automatisch abfragen konnte.
- Die erledigt der gpg-agent, der wiederum pinentry-curses zur sicheren Übertragung der Passphrase vewendet.
- In der gpg.conf muss angegeben werden, dass der gpg-agent verwendet werden soll (use-agent).
- Und in welchem Modus dieser verwendet werden soll (pinentry-mode loopback).
- In der gpg-agent.conf muss dem gpg-agent erlaubt werden den loop-back-pinentry durchzuführen (allow-loopback-pinentry).

Lösung
Benötigt duplicity den ssh-key im PEM-Format, wenn duplicity sich via ssh anmelden soll. - Verifiziert durch Duplizierung des Fehlers.
# ssh-keygen -p -f /root/.ssh/id_rsa -m pem -P "" -N ""
Änderung des Formats des ssh-Keys von OPENSSH zu PEM (Privacy-Enhanced Mail)
ssh-keygen
| Option | Beschreibung |
|---|---|
| -p | Fordert die Änderung der Passphrase einer privaten Schlüsseldatei zu ändern, anstatt einen neuen privaten Schlüssel zu erstellen. Das Programm fordert Sie auf, die Datei mit dem privaten Schlüssel, die alte Passphrase und zweimal die neue Passphrase einzugeben. |
| -f | Dateiname. Gibt den Dateinamen der Schlüsseldatei an. Hier der Pfad /root/.ssh/id_rsa |
| -m | Geben Sie ein Schlüsselformat für die Konvertierungsoptionen -i (Import) oder -e (Export) an. Die unterstützten Schlüsselformate sind: "RFC4716" (öffentlicher oder privater RFC 4716 / SSH2-Schlüssel), "PKCS8" (öffentlicher PEM PKCS8-Schlüssel) oder "PEM" (öffentlicher PEM-Schlüssel). Das Standardkonvertierungsformat ist "RFC4716". Wenn Sie beim Generieren oder Aktualisieren eines unterstützten privaten Schlüsseltyps das Format "PEM" festlegen, wird der Schlüssel im alten privaten PEM-Schlüsselformat gespeichert. Hier soll der ssh-key in das PEM-Format konvertiert werden also: -m PEM.
in engl.: Specify a key format for the -i (import) or -e (export) conversion options. The supported key formats are: "RFC4716" (RFC 4716/SSH2 public or private key), "PKCS8" (PEM PKCS8 public key) or "PEM" (PEM public key). The default conversion format is "RFC4716". Setting a format of "PEM" when generating or updating a supported private key type will cause the key to be stored in the legacy PEM private key format. |
| -P | passphrase
Stellt die (alte) Passphrase bereit. |
| -N | new_passphrase
Stellt die neue Passphrase bereit. |
| "Passphrase" | Da hier weder im alten noch im neuen Format für den ssh-key eine Passphrase verwendet wurde bzw. werden soll, wird zwischen den beiden " nichts eingetragen: "" |

RAID-Alignment (Ausrichtung)
- Datenträger, RAID-Verbunde und Dateisysteme fassen Daten jeweils für sich in Blöcke zusammen, bevor sie gespeichert werden.
- Diese Blöcke haben im Allgemeinen alle unterschiedliche Größen.
- Um eine optimale Performance zu erzielen, sollten die Größen aufeinander abgestimmt sein.
- Dafür muss zunächst die sog. Chunk Size, also die Datenmenge, die in einem einzelnen Schreibvorgang geschrieben wird, bekannt sein.
Ermittlung der Chunk Size
# mdadm -D /dev/md0 | grep "Chunk Size"
- Bei einem RAID 5 mit Standardeinstellungen liefert dies z.B.:
Chunk Size : 512K
- Es werden also 512 KiB Chunks verwendet.
Berechnung des Alignments
- Hieraus können, zusammen mit der Anzahl der Partitionen und des RAID-Levels, die Dateisystem-Parameter berechnet werden.
- Am einfachsten geht das mittels eines Raid-Stride-Calculators.
- Alternativ können die Parameter auch von Hand ermittelt werden.
- block-size - Die Größe der Dateisystemblöcke in Bytes. Heutzutage werden fast ausschließlich 4096 Byte (4 KiB) Blöcke verwendet.
- stride-size - Die Chunk Size umgerechnet in Dateisystemblöcke. Bei 512 KiB Chunk Size mit 4 KiB Blöcken ergibt sich 512 KiB/ 4 KiB = 128.
- stripe-width - Die Größe eines Datenstreifens, also die Menge an Blöcken, die geschrieben wird, wenn ein voller Chunk auf jedes Laufwerk geschrieben wird. Diese berechnet sich aus stride-size * Anzahl der effektiv nutzbaren Partitionen. Bei einem RAID 5 über 4 Partitionen ergibt sich hier 128 * 3 = 384.
- Details zur Anzahl der effektiv nutzbaren Partitionen findet man im Artikel Hardware:Storage:RAID.
- Sind die Parameter ermittelt, wird das Dateisystem erstellt:
# mkfs.ext4 -b 4096 -E stride=128,stripe-width=384 /dev/md0
