Appendix D. Troubleshooting
This discusses the following suggested solutions to problems with DX Storage:
• Section D.1, "Restoring Domains and Buckets"
• Section D.2, "Resolving Duplicate Domain Names in a Mirrored or Disaster Recovery (DR)
Cluster"
• Section D.3, "Using DX Content Router to List Buckets and Objects"
• Section D.4, "Boot Errors"
• Section D.5, "Configuration"
• Section D.6, "Operational Problems"
D.1. Restoring Domains and Buckets
This section discusses how to recover domains or buckets after they have been accidentally
deleted. When you delete a bucket, for example, the objects it contains are not deleted but they are
inaccessible until you recover the bucket.
To recover a deleted domain or bucket, you must have all of the following:
• You must know the name of a child object.
For example, if a bucket was deleted, you must know the name of an object contained in that
bucket.
• The DX Content Router product.
You must use the DX Content Router's metadata enumerator to find the contained object's
metadata. The metadata enumerator iterates through all objects in a cluster and returns
information about those objects. For example, if a bucket was deleted, the metadata enumerator
cannot locate the bucket but it can locate objects contained in the bucket (because the objects
were not deleted). Knowing the name of an object, you can find the bucket's UUID, which you use
to recover the bucket.
For more information about using the metadata enumerator, see the Enumerator chapter in the
SDK Overview. For information on creating DX Content Router rules, see the DX Content Router
Setup and Configuration Guide.
• You must upload a realm (that is, user list) for the domain or bucket you recover. There is no way
to retrieve the user list after the domain or bucket has been deleted.
D.1.1. Recovering a Deleted Domain
To recover a domain, you must know the name of a bucket that was contained in the domain. The
following procedure shows how to create the domain from the command line using the previous
domain's UUID. If you create a domain with the same name in the Admin Console, the new domain
has a different UUID. Because all the buckets created in the domain before it was deleted reference
the domain's UUID as Castor-System-CID, the buckets are inaccessible unless the new
domain's UUID is set to the previous value.
You must also know the Castor-Authorization header corresponding to the domain's
protection setting, which is one of the following:
