    Datastore disappeared after disk replacement in a RAID 1 array (ESXi 6.7)

    ziffusion Lurker

      I used to have a datastore defined across 2 disks (spanned 2 partitions on 2 disks). After some disk maintenance the datastore disappeared.

       

      The 2 vmfs partitions on 2 disks seem to still be there:

      naa.6842b2b07523ad0022b0972b1b2d9380:1

       

      Here are a couple of things I see in the logs:
