   SUSE Recommended Update: Recommended update for mdadm

Announcement ID:    SUSE-RU-2021:3138-2
Rating:             moderate
References:         #1180661 #1182642 
Affected Products:
                    SUSE MicroOS 5.1

   An update that has two recommended fixes can now be


   This update for mdadm fixes the following issues:

   - Remove Spare drives line from details for external metadata.
     (bsc#1180661, bsc#1182642)
     - Arrays with external metadata do not have spare disks directly
       assigned to volumes; spare disks belong to containers and are moved to
       arrays when the array is degraded/reshaping. Thus, the display of zero
       spare disks in volume details is incorrect and can be confusing.
   - Don't associate spares with other arrays during RAID Examine.
     (bsc#1180661, bsc#1182642)
     - Spares in imsm belong to containers, not volumes, and must go into a
       separate container when assembling the RAID. Remove association spares
       with other arrays and make Examine print separate containers for
       spares. Auto assemble without config file already works like this. So
       make creating a config file and assembling from it consistent with
       auto assemble. With this change, 'mdadm -Es' will add this line to
       output if spares are found: 'ARRAY metadata=imsm
