similar to: viewing, if not editing, NFSv4 ACL's from Samba shares

Good morning! I'm reviewing some corporate storage setups involving NetApps, where the NetApp stores what they call "UNIX Qtrees". So far, so good: those allow the setting of access to the data with NFS4 ACL's, which are fairly sophisticated and allow multiple groups or even multiple users to be granted write access.or read access, besides the normal UNIX group owner. That works

Hi, I am looking for a method of syncing NFS directories (Netapp qtrees) that contains NFSv4 ACLs. We copy qtrees (millions of files, xx TB) from one qutree into another one. The only tool we currently use is (netapp internal) ndmpcopy, it preserves ACLs but is slow. Netapp "xcopy" tool is also not aware of NFSv4 ACLs. rsync that is aware of NFSV4 ACLs would be a smart solution for

Hi, we recently purchased a NAS (QNAP) with Samba version 3.5.2. In order to assign permissions on subfolders we enabled Posix ACL's. The problem is that we need to allow only a certain group to do this. The ACL entries in our smb.conf are the following: acl compatibility = auto acl check permissions = Yes acl group control = Yes acl map full control = Yes

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 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 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 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 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

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

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?

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

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

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

Hello, all my data are hosted by a server and exported with nfsv4. For example if a user logs in on a client, /home and /data are exported with nfsv4 and autofs. Now if the user delete some files, the trashcan under gnome doesn't change its status nor doesn't show the deleted files if opening the trashcan window. Also the user isn't able to copy or move files between the exported

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
