Preserving Headers

Preserve the existing domain or bucket. See SCSP Headers.

  • Look for Policy-* headers, such as Policy-Replication, Policy-ECEncoding, Policy-ECMinStreamSize, Policy-Versioning, and Policy-Lifecycle, and the x-tenant-meta-name header that Gateway uses to group domains under a tenant.

  • Add the preserve SCSP Query Arguments to the COPY request to verify any custom metadata existing on the object is carried over to the copy. (v9.2)

  • Include the header name with the new value on the request to overwrite an existing value. 

See Headers to preserve in SCSP COPY.

  1. Locate and record a critical log message related to the missing bucket, resulting from a named object within it being inaccessible. 

    Code Block
    languagebash
    Bucket 'mybucket' (uuid=75edd708dc250137849bbf590458d401) in domain 'example.com' has been deleted with orphan content. 
Consider recreating.

  2. Copy the UUID listed within the log message to recreate the missing bucket.

    Code Block
    languagebash
    75edd708dc250137849bbf590458d401

  3. Create a new bucket with a POST that references the deleted bucket's UUID in the recreatecid query argument:

    Code Block
    languagebash
    $ curl -i -X POST --location-trusted --post301 --anyauth --user 'admin:password' --data-binary '' \
  -H 'Content-type: application/castorcontext' \
  -H "Policy-*: {if needed}" \
 'http://{host}/mybucket?domain=example.com&admin&recreatecid=75edd708dc250137849bbf590458d401'

  4. Include the below versioning header when restoring all versions from the deleted bucket:

    Code Block
    -H "policy-versioning: enabled"
Note

Warning

If you restore a bucket (that WAS versioned) and do not include the versioning header (see above) when recreating the bucket, the old versions will immediately start getting cleaned up by the Health Processor.

Note

  • If you try to restore all versions from the deleted bucket, include this header. If you are recreating the bucket only to delete the bucket contents, there is no need to include this header.

  • If you are recreating the bucket that if you need to recover the metadata from the deleted bucket, do this before recovering the bucket:

    Code Block
    curl -u admin:<admin password> -I --location-trusted "<Swarm node>/<UUID>?etag&admin&readmarker”
