Ich richte einen neuen Dateiserver mit der gleichen Speicherkonfiguration wie mein vorhandener Server ein, aber die Prozedur schlägt fehl und ich kann nicht herausfinden, warum. Mein Ziel ist es, ein TrueCrypt-Volume auf einem RAID 10-Volume zu erstellen. Wenn ich jedoch starte truecrypt -c
, zerstört es das RAID-Volume. Das gleiche Verfahren hat auf meinem vorherigen Server funktioniert, ich bin mir also nicht sicher, was los ist.
Meine Vorgehensweise:
# create a data partition on each disk (/dev/sdb, /dev/sdc, /dev/sdd, /dev/sde):
fdisk /dev/sdX
new, p, 1, 4096, 2930273071, type, da, write
# combine data partitions into raid10 array:
mdadm --create /dev/md0 -v --raid-devices=4 --chunk=512 --level=raid10 --layout=f2 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1
# create a truecrypt volume on the new data partition /dev/md0:
truecrypt -c /dev/md0
Kurz nachdem TrueCrypt gestartet wurde, erhalte ich von Mdadm einen Komponentenfehler für eine oder mehrere der Festplatten:
$ cat /proc/mdstat; echo; mdadm --misc --detail /dev/md0

Dies ist kein tatsächlicher Festplattenfehler, da a) smartd keine Probleme mit den Festplatten feststellt und b) ich auf jeder Festplatte einzeln ein vollständiges TrueCrypt-Volume erstellen kann.
Ich habe auch versucht, eine Partition auf / dev / md0 (sowohl 83 / Linux- als auch da / Non-FS-Daten) zu erstellen und dann ein TrueCrypt-Volume auf der Partition / dev / md0p1 (von der diese dmesg-Ausgabe stammt) zu erstellen, aber dies ist nicht der Fall Arbeit entweder.
Ich gehe davon aus, dass TrueCrypt mdadm-wichtige Metadaten irgendwie zerstört. Aber was seltsam ist, dass dieses genaue Verfahren zuvor gut funktioniert hat. Was ist hier los?

BEARBEITEN: Als diese Prozedur funktionierte, verwendete sie wahrscheinlich TrueCrypt 6 - ich werde es mit 6 versuchen, um zu sehen, was passiert. Ich werde mit den Ergebnissen aktualisieren ...
