Those limitations are valid in encryption for security > reasons and it doesn't make sense to carry them over in EC. > This JIRA aims to store EC schema and cell size on {{INodeFile}} level. For > simplicity, we should first implement it as an xattr and consider memory > optimizations (such as moving it to file header) as a follow-on. We should > also disable changing EC policy on a non-empty file / dir in the first phase. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
