    DeviceDisappeared event detected on md device /dev/md14

    Hi all,

     

    This our editors started complaining of speed issues and MC 2018.5 started reporting some Exceptions. As this was happening across projects and workspaces, we went to check out our NEXIS log and noticed that around the time editors are gertting errors we're seeing the following error:

     

    DeviceDisappeared event detected on md device /dev/md14

    It's also followed by a detected capactiy changer info line: md14: detected capacity change from 26197557248 to 0

     

    Some time later there will be a warning that a NewArray event is detected for md14:

      mdadm TGroupSDA-top NewArray event detected on md device /dev/md14

     

    The NEXIS and all clients are 18.9.1.16. Any help woul dbe appreciated.

    if this was a single SDA SSD, i would expect to see the device listed as /dev/sdX/serialnumber, however, /md is multiple device, as in a raid group. I wonder if both of the SDA metadata SSDs are going offline simultaneously - controller or chassis failure. You should get in contact with avid support URGENTLY.
