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 n...

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: -...

Good morning, in order to post proper documentation, what logs (or log level) do I need to troubleshoot a Centos 7.6.1810 3.10.0-957.27.2.el7.x86_64 tha tis running a NFS server on top LVM on top of XFS on top of VDO on top of MDAM on a 6 SSD disk RAID6 ? This physical NFS server is servign 2 NFS v4.2 shares to 2 physical KVM virtualization hosts. When remote NFS clients start doing intensive

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 had Samba shares on top of the NFSv3+ACL mounts. In our setup, we are relying on NFSv4 ACL inheritance. Here's an example of an ACL on a file (as created by a touch command): roo...

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 time (even deliveries are managed by direc...

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 vie...

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 tim...

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:...

...n here if that's ok. Here's what we have, and what we'd like to do: Storage is a Netapp (cluster mode CDOT 8.2 I believe), it's NFS exported to our linux system. Linux system is CentOS 6 and can NFS mount the Netapp using version 4. NFSv3 doesn't support ACLs with Netapp, but NFSv4 does with the nfs4_setfacl and nfs4_getfacl commands. We'd like to share out the NFS mounted volume with samba, and retain the NFSv4 acl capability so that Windows users can set advanced permissions on the files. Is this possible? I've seen posts about the ZFS ability and the GPFS a...

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?

...caching data (mainly dovecot index files) but they have to revalidate the cache frequently asking to the NFS Server if the file is changed (via GETATTR) but the file never change because only this client opens it. So the NFS Server is wasting operations with (unnecessary) GETATTR request. With NFSv4 and delegation you can practically eliminate these (GETATTR) requests and speed up your NFS server (instead of buy SSD disk). This because with delegation a client open file and since is the only client to open these file (that is true with Director) the NFS server delegate the client to manage...

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
