hi there - is it possible to share a directory via samba and (kernel-)nfsv4 in parallel and make samba use (ie.: read, write and enforce) nfsv4 acls to implement winnt-acls? i know that using nfs3 and posix acls is working halfway okay, but couldn't find anything useful for nfsv4 and the associated acls - sorry if i missed something obvious. i played around with the nfs4acl_xattr and

I have been trying all sorts of things to get this working. nfsv4 works fine if I just use the nfs-v3 form of export i.e. /nfs4exports 192.168.230.237/24(ro,fsid=0,sync,insecure,no_root_squash,no_subtree_check,squash_uids=0-99) /nfs4exports/NDG 192.168.230.237/24(rw,insecure,no_subtree_check,nohide,sync,no_root_squash,squash_uids=0-99) but this is inherently open to all on this machine. so then

I have a situation where I need to share, via Samba, a filesystem mounted via NFSv4. I'm struggling with the best way to make Samba see the NFSv4 ACLs and enumerate them to provide the proper SMB/CIFS access to the files, instead of "Access Denied" errors that I currently get. Looking at the Samba source, the only obvious NFSv4 stuff appears to be the following: - zfsacl, available

Hi, We are running into a problem with a Samba setup and would like to know if a current fix or workaround is at all possible. Our setup is a NetApp filer serving NFS v4 that is mounted by Solaris and Linux servers. On those servers we are using Samba to create shares of those NFSv4 mounted filesystems. We are migrating to this NFSv4 setup from an existing Solaris NFSv3+Posix ACL setup that also

Good morning, folks. I'm involved in a project to enforce NFSv4 ACL's across a variety of storage platforms, in particular NetApps sharing NFS. That works fiine with the NetApp NFS qtrees, but we'd like to share those with CIFS clients as well. This works, and restricts access the way we expect NFSv4 ACL's to work, but the Windows clients cannot view any of the security settings

hi all, i'm managing a large installation of a dovecot cluster in director + NFS backend architecture and we are moving from NFSv3 to NFSv4. Our NFS server is a Netapp in clustered mode and reading technical specs of NFSv4 delegation feature it seems that enabling delegation in this type of dovecot architecture should bring great benefits: only one backend server access a specific mailbox at a

Hi, Just out of curiosity what is in nfsv4 delegation that you think would give a benefit on your configuration? If I read back the thread you seem to have dovecot configured with director ring in front of the backends. In that case Dovecot already manages storage in a way that only one of the backends is accessing each users data at a time. So I can?t see anything but problems form enabling

HI all, I have configured a CentOS 6.3 x86_64 as a NFSv4 server and I am suffering errors like this: perl[7889]: segfault at a80 ip 00007fb870227ea2 sp 00007fff2fecda30 error 4 in libperl.so[7fb870193000+162000] The symptoms are the same as described in this thread: http://serverfault.com/questions/235059/vfs-file-max-limit-1231582-reached Can anyone confirm that is a bug when NFSv4 is

> Samba provides the "nfs4acl_xattr" vfs module precisely for that. I am not an expert in Windows ACL, but where do you see that the nfs4acl_xattr vfs module provides the support for "manage the ACLs on the OS of the Samba host directly?" From the Wiki page, https://wiki.samba.org/index.php/NFS4_ACL_overview, it implies the following four operation modes are possible.

FreeNAS / FreeBSD have native NFSv4 ACLs. They do however lack kernel oplock support so there are perhaps some caveats in that regard.

just a quick update: no issues with NFSv4.0 (load is slowly growing, currently ~7k mailboxes) instead, bad news from delegation front, we enabled it for a couple of days but we ran in ugly issues: processes went in "uninterruptible sleep" state, load average gets huge, reboot was the only escape :-( -brd Alessio Cecchi wrote: > Il 12/06/2015 13:02, brd ha scritto: > >Alessio

Hi people, I'm testing Samba 4.0.17 running as classic pdc mode under FreeBSD 10 and 9.2 , all shares are on ZFS volumes, i would like to use UFS instead of ZFS , but according the wiki page https://wiki.freebsd.org/NFSv4_ACLs nfsv4 inheritance flags works only with ZFS , i tried the parameters inherit acls and inherit permissions with module vfs_zfsacl on the UFS shares but got no success

Hi all, are there any non-commercial solutions (apart from solutions like Dell EMC, IBM and NetApp) around that allow to simultaneously access the same file system via NFSv4 and Samba exports in a (nearly) non-conflicting manner, especially w.r.t. to NFSv4/Windows ACL incompatibilities?

Thank you for that, i did have a good look at that one. And i use Debian 9, if you test what i posted below in the thread, you will see NFSv4 works fine. Below is missing one more thing, the "allow to delegate (kerberos only) " on the computer object in the AD, should be enabled. And yes, i've see bugchecks also but only on my debian .. Lenny.. Stt.. ;-) .. Its my last lenny

Hi Timo, I just read about NFSv4 now being included in SuSE and Redhat Enterprise versions, and although I don't use it myself, wondered how this will impact Dovecot for those using it? Will it make life easier? Or is it even supported currently? Just curious... thanks... -- Best regards, Charles

Hi everybody and thanks to those persons who make klibc being possible. I am booting a lessdisks system from a server. I have got it in NFSv3 but I would like use the features of NFSv4. I am using initramfs-tools so I have in my initrd.img the utility nfsmount wich make possible booting in NFSv3. I would like know if exists some version of nfsmount or some patch or, if does not, some program (a
