Guten Tag,

bei mir liegt das selbe Problem vor und ich brauche dringend Hilfe.

Gruß

Dennis


Hallo zusammen,

ich brauche dringend Hilfe bei der Wiederherstellung meins Raid5-Volume. Als vorhin der Kopiervorgang auf die NAS abbrach und ich diese nicht mehr ansprechen konnte, vollzog ich einen Neustart. Anschließend erhielt ich folgende Fehlermeldung in der GUI. Die einzelnen HDDs zeigen keine Defekte an, auch die SMART-Werte passen. Es gibt jedoch keine Option diesen Fehler zu "reparieren". Was muss ich tun um die Daten nicht entgültig zu verlieren?

Vielen Dank vorab für eure Hilfe.
Detlef

    If your RAID is  RAID 1 or JBOD, you can try to get data from Linux:

    What's the results when you use following commands:

    fdisk -l
    cat /tmp/sto_log
    cat /proc/mdstat
    mdadm --examine /dev/sda3
    mdadm --examine /dev/sdb3
    mdadm --examine /dev/sdc3
    mdadm --examine /dev/sdd3

    @dsz376

    You should use "root" to check commands.

    According to mdadm and /proc/mdstat the array is degraded. For some reason sdc3 is kicked off the array at 3 April.

    According to /tmp/sto_log the volume can't be mounted. So I think the filesystem is damaged. You can try to repair that
    su
    fsck /dev/md2
