Hi, We want to export SMB shares via Spectrum Scale CES nodes. The filesystem has ACL style set to “all” and we must set it to nfs4 with mmchfs -k nfs4 . The filesystem currently has millions of files with POSIX ACLs. Will this mmchfs command result in any performance impact, such as a major rewrite of metadata? Thanks.
