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

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 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 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, 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

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, last day I tried to enable "nfsv4 delegation" on my cluster (enable nfsv4.0 and read delegation on Netapp and remount the volume on Linux Centos 6.7 clients with Dovecot+Director). It was a failure, after some minutes the load on clients was high, and in dovecot.log I found these errors (repeated continuously): Aug 17 20:28:17 pop01eeh dovecot: imap(info at domain.com): Error:

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

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

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. I'm having trouble accessing a shared directory over NFSv4 on a CentOS 4.5 machine. My export file reads /test 10.0.0.0/255.0.0.0(ro,async,insecure,nohide,no_subtree_check) Running the mount command with NFSv4 as the filesystem gives me a permission denied error. [root at pebble-anoop ~]# mount -v -t nfs4 pebble-anoop:/test/ /mnt/ mount: pinging: prog 100003 vers 4 prot tcp port

Hi, I have a relatively loaded CentOS5 server (64-bit, dual core) and a mixed bag of Fedora 6/CentOS4, 32-, and 64-bit clients. NFSv3 works without problem. References over NFSv4 hang occasionally, in particular on file opening. I wonder whether there is anybody here who can help to trace it, or can suggest a more appropriate forum? The one hang that I have been able to trace involved

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

>From what I've read so far Samba supports POSIX ACLs, correct? If so, will they work over NFSv4 exports? The reason I'm asking is as follows: We're considering redoing our storage systems which currently also house Samba servers. These are currently running on Linux boxes with NFS exports to the rest of our networks. Many machines with massive amounts of storage, one Samba
