Defekte Platte im RAID5 tauschen

  • I tried it once again, without Putty, direct an after a reboot.


    for mdadm --stop /dev/md127


    i receeved:


    mdadm: Canno get exclusive access to /dev/md127: Perhaps a running process, mounted filesystem or active volume group?


    gui shows (as all services had been stopped before) following:



    what else can I do?

  • thank you for looking
    The link I had posted shows Diagnostik > Processes (doesn`t is?)
    ...


    root@OMVneu:~# lsof dev/md127

  • it seems as it happen nothing...

    That would suggest there are no open files on the array ?( which makes no sense.


    Let's see if it will force a stop mdadm --stop --force /dev/md127 if that errors again then look at the output of this


    ps aux the list will be long but you are looking for something that is accessing the raid or a reference to Plex

  • root@OMVneu:~# mdadm --stop -- force /dev/md127
    mdadm: No devices given.
