Root Cause

The snapshot repository (S3, GCS, or filesystem) is unreachable due to incorrect credentials, network issues, or insufficient permissions, preventing Elasticsearch from writing verification blobs.

generic

中文

快照仓库（S3、GCS或文件系统）由于凭据错误、网络问题或权限不足而无法访问，阻止Elasticsearch写入验证blob。

Workarounds

  1. 85% success Verify S3 credentials by running: aws s3 ls s3://bucket/backups/ --profile elasticsearch-snapshot from the Elasticsearch node. If it fails, update the repository with correct credentials: PUT /_snapshot/my_repo { 'type': 's3', 'settings': { 'bucket': 'bucket', 'region': 'us-east-1', 'access_key': 'CORRECT_KEY', 'secret_key': 'CORRECT_SECRET' } } 
    Verify S3 credentials by running: aws s3 ls s3://bucket/backups/ --profile elasticsearch-snapshot from the Elasticsearch node. If it fails, update the repository with correct credentials: PUT /_snapshot/my_repo { 'type': 's3', 'settings': { 'bucket': 'bucket', 'region': 'us-east-1', 'access_key': 'CORRECT_KEY', 'secret_key': 'CORRECT_SECRET' } }
  2. 80% success Check the Elasticsearch logs for detailed error messages (e.g., AccessDenied, 403) and fix the bucket policy to allow s3:PutObject for the Elasticsearch role. Example policy: { 'Effect': 'Allow', 'Action': 's3:PutObject', 'Resource': 'arn:aws:s3:::bucket/backups/*' } 
    Check the Elasticsearch logs for detailed error messages (e.g., AccessDenied, 403) and fix the bucket policy to allow s3:PutObject for the Elasticsearch role. Example policy: { 'Effect': 'Allow', 'Action': 's3:PutObject', 'Resource': 'arn:aws:s3:::bucket/backups/*' }

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Increasing the timeout setting (e.g., repository.s3.socket_timeout) may mask the issue but does not fix underlying credential or permission problems.

  2. 90% fail

    Recreating the repository with the same settings will fail again because the root cause (e.g., IAM role or bucket policy) is unchanged.
