Accessing a bucket or object in the S3 server fails with S3 internal errors

If the nodes of a cluster fail abruptly or if there is a crash, the named metadata attributes stored in the extended attribute of the file system may not get flushed to the disk correctly. Hence, the correct value of the named attribute data is not recovered.

This causes the operations which are dependent on the named attribute to fail. The S3 server reports ACL corruption errors in the log. The object data or directory information remains valid but named attribute may be in invalid state. This results in failure in accessing the bucket or objects in the S3 server.

Workaround:

The fix for this issue will be available in the next patch release. Veritas recommends that you take preventive measure to avoid system crash when S3 write operations are in progress.
