Hi All, Are there any special CTDB/SMB configuration settings/dependencies to manage Winbind across CTDB managed servers authenticating via Active Directory(AD)? An example would be Samba's IDMAP backend for Winbind: RID vs. AD or tag Winbind to a primary CTDB node and point other nodes to authenticate from AD via proxy primary CTDB node? /etc/sysconfig/ctdb on all nodes is as follows:

Hi guys, I try to set up two identical installed up to date CentOS6 machines with Glusterfs/CTDB/Samba . I have set up Glusterfs and it works. I have set up CTDB from CentOS and it seems to work too. Samba is AD integrated and works mainly. The main problem is that file locking seem to not work between the machines at all. If two Win7 clients try to open an document from the same Samba server

Hi, I am setting up ctdb samba, and have hit a brick wall trying to solve the following issue. 1. getent does not retrieve the list of domain users or groups (wbinfo works fine) I'm not sure what I'm missing but I've almost spent the whole day trying to resolve this one and haven't made any progress :-( Any help or suggestions are appreciated My configuration is

I have been working on a CTDB cluster on and off for a while now. I had it working great for a while. THen I decide dthat I wanted to change the configuration of my replicated volumes. I changed my DRBD configuration to match my desired configuration. Now I can get the CTDB to work quite right. I am able to join the cluster to the domain without issues. I can also list my ad users and groups using

Dear All, I've been upgrade from 3.6.x to 4.1.x (Member server) All Win 7 Pro 64. While in 3.6.x there is no such report on the issue,just people complain about the slowness While in 4.1.x there are random report on this issue not everyone but more to a particular person... That seem to be happening from 4.1.6, 4.1.11 and 4.1.12 And I've really no idea why or how. Any suggestion to

Hi all, At some point recently my customers can no longer see GPFS snapshots under the Windows Previous Versions tab. It simply says "No previous versions available". If a fileset is exported with the flag "force user = root" then Previous Versions *are* displayed. [2016/07/06 10:07:35.602080, 3] ../source3/smbd/vfs.c:1322(check_reduced_name) check_reduced_name:

Hi Samba Users, I'm in the process of building a Samba4 CTDB /GPFS Cluster joined as a member server to AD that also supports ACL's . It has taken some time but almost everything is working now :) . My one outstanding issue is editing files using Excel 2007 on Windows 7 results in a 'Document not saved' error. I believe this is an issue with the SMB2 protocol as I can edit the same

But after setting up ctdb and samba und running it my two nodes freezing for a while And ctdb and samba are down again. On Both nodes My /etc/sysconfig/ctdb: CTDB_RECOVERY_LOCK="/cluster/recovery/recovery"

hi guys, we're evaluating the available clustering options to get ctdb up and running for a highly available file server. we've set up both gluster and ocfs2 both on seperate 2 node setups. ocfs2 seems to provide better throughput and iops to samba clients than does gluster and that is comparing a single node server to a ctdb clustered 2 node server. problem with ocfs2 is that i've

Hi, everyone, I setup two-node samba cluster with ctdb and glusterfs. When one node fails, another node can takeover ip and cifs sessions, so application can not breaks. Linux cifs client works fine when disable one node. However, it does not work under windows xp. I am copying a big file to samba share, meanwhile I disable the connected node, then copy break with "The specified network

Dear Samba Community, we recently did upgrade our data server cluster from Debian Squeeze (Samba 3.5.6) to Debian Wheezy (Samba 3.6.6). The cluster is configured to act as BDC too. After the upgrade, connecting to the server works for a short while and then users experience disconnects and are unable to reconnect the mapped network drive (mostly on Win7/64bit; connections from Linux machines work

Hi , I have set up a 2-node CTDB cluster serving NFS and CIFS authenticating Windows and Linux users via Active Directory. The setup works fine, except only one server in the CTDB-cluster is able to join the AD domain at a given instance. If you manually add the other server into AD, the already connected server gets disconnected. There is no specific error message logged in /var/log/message or

Hi there, I am looking into using CTDB between a PDC and a BDC. I assume this is possible! However I have a few questions: 1: Do I have to use tdb2 as an Idmap backend? Can I not stay with ldap? (from the CTDB docs: A clustered Samba install must set some specific configuration parameters clustering = yes idmap backend = tdb2 private dir = /a/directory/on/your/cluster/filesystem It is

Hi Martin I just found the file, it's a config file that about 250 hosts read every half an hour so it makes sense this is getting some contention. However, the strange thing is, the share the file is in is a read-only share: [dist$] comment = Windows dist path = /path/to/share wide links = Yes browseable = Yes read only = Yes guest only = Yes

Hello, maybe there is someone they can help and answer a question why i get these network screen on my ctdb clusters. I have two ctdb clusters. One physical and one in a vmware enviroment. So when i transfer any files (copy) in a samba share so i get such network curves with performance breaks. I dont see that the transfer will stop but why is that so? can i change anything or does anybody know

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm in the progress of setting up clustered samba with ctdb. Samba is ADS-member server. WINS server is configured on two of our 2003-servers. When samba runs for a couple of hours I checked the WINS servers and saw that samba/nmbd registrred only the private interface addresses (192.168.1.x) and not the public interfaces (10.0.0.41,42).
