Windows NFS Server ACLs

Question

Hello,

Does Windows Server for NFS support Linux ACLs? Specifically, I’m referring to using setfacl or nfs4_setfacl on a Linux client to set Linux ACLs on an NFS share hosted by a Windows Server 2019 NFS server.

Thank you,

Tim

Hello there,

Windows does not support NFS V4 ACLs. If a file system is to be exported over NFS V4/Linux, then it must be configured to support POSIX ACLs (with the -k all or -k posix option of the mmcrfs command). This is because NFS V4 Linux servers only handle ACLs properly if they are stored in GPFS as POSIX ACLs.

Hope this resolves your Query !!
