Hallo zusammen
ich habe ein etwas „interessantes“ Problem mit meinem Software-RAID. Ich habe zwei externe 2TB USB Festplatten (sdb & sdc) die je in einem LVM arbeiten und aus mehreren RAID Partitionen bestehen. Das Bild anbei zeigt die Konfiguration genauer.
Wenn ich nun den Server Reboote dann lädt er das Software-RAID leider nicht komplett sondern nur die Platte sdb (siehe Ausgabe cat /proc/mdstat).
Wenn ich mit mdadm die einzelnen RAID Partitionen wieder einbinde, dann werden sie resynced und es läuft super bis zum nächsten reboot.
Kann mir hier jemand einen Tipp geben woran das liegt?
Danke und Grüße
