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 everybody, I have tested CTDB+GFS2+CMAN under Debian. It works good but I do not understand some points. It is possible to run the CTDB defining it under services section in cluster.conf but running it on the second node shuts down the process at the first one. My CTDB configuration implies 2 active-active nodes. Does CTDB care if the node starts with clean_start="0" or

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

Hi, [Context : ubuntu 11.11 64bits, cman, clvmd, gfs2, ctdb, samba, likewise-open, all running fine except...] I've setup ctdb to manage public_addresses (to manage one virtual ip actually), and I've explicitely told smb.conf that netbios name = foobar_cluster I've done that *after* I've manage to make samba, likewise-open and AD to work nicely together. I guess now all the

I have been running ctdb on our cluster for ~6 months to serve a gpfs filesystem over nfs. It has been running a treat :) ! Recently the servers were upgraded to redhat 5.7 and ctdb-1.0.112-1.el5 is part of the package list. Since the upgrade the log file is filled with messages 2011/10/04 12:35:37.933801 [ 1779]: basename: missing operand 2011/10/04 12:35:37.933850 [ 1779]: Try `basename

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

Is there a way to get CTDB or Samba status/stats w/o forking a process? I am looking into writing Prometheus exporters for these. I'd prefer to make a "C" call in Golang than fork a process and scrape STDOUT. What are my options?

Hello, I try to set up a clustered samba server (on Novell SLES11SP2) based upon CTDB and NFS. My problem is that I do not yet understand the structure of the setup when using NFS. I followed the documentation in http://wiki.samba.org/index.php/CTDB_Setup#Setting_up_CTDB_for_clustered_NFS As far as I understand this documentation, it should be possible to set up a samba cluster say having 3

Hi, i configured a running three node CTDB SAMBA cluster (hope so). Virtual ip's are floating between the nodes after faling one of them. Im using SAMBA 4.11.6 on Ubuntu 18.04. Samba was compiled from source. I configured some systemD start/stop scripts for samba (smbd, nmbd) and winbind, also disabled them for manage via ctdb. I enabled ctdb to mange samba and winbind via this

Hello, I am trying to migrate samba domain controller (version 3.6, passdb backend = tdbsam) to a new clustered environment with CTDB (same samba version). I have a functional ceph storage and the ctdbd configured according to the documentation. However, all available guides are for the fresh installations and I can't migrate current data into the CTDB. Simply restoring tdb database into

Hi, in the following scenario I've got the Problem of "STATUS_SHARE_VIOLATION". Client A (with User 1) copies a file to share X. (with: DENY_NONE 0x120196 WRONLY NONE) Client B (with User 1) reads this file from share X (with: DENY_NONE 0x120089 RDONLY NONE) Now Client C (with User 1) wants also to read this file from share X and gets the STATUS_SHARE_VIOLATION.

Hello all, First of all, apologies if this isn't the right location for this question, I couldn't find a CTDB specific mailing list or IRC so I figured the general one would be appropriate. Please let me know if this question is better placed elsewhere. I'm trying to test clustered samba and have a two node CTDB setup (Following the guide here:

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 All, My site has two separate clustered Samba instances (managed by two independent CTDB instances) running over GPFS. In the last couple of weeks, we have seen a recurring issue that causes the `smbd` process in *one* of these instances to become unresponsive (as seen by CTDB), which results in flapping of CTDB and multiple IP takeover runs. The symptoms that we observe are: 1) Samba

Hi everybody, I just updated my ctdb node from Samba version 4.9.4-SerNet-Debian-11.stretch to Samba version 4.9.8-SerNet-Debian-13.stretch. After restarting the sernet-samba-ctdbd service the node doesn't come back and remains in state "UNHEALTHY". I can find that in the syslog: May 16 11:25:40 ctdb-lbn1 ctdb-eventd[13184]: 50.samba: samba not listening on TCP port 445 May 16

Hi everyone, I'm setting up a clustered Samba+CTDB in front of CephFS and am running into an issue during failover. For the most part everything seems to work: the IP moves quickly, smbd is started on the right node, etc, but if there is an IO load from a client during failover (e.g., copying a big directory full of files in File Explorer), it pauses for a couple of seconds and then pops up

Hi, i have a 2node ctdb-samba-cluster on debian squeeze-machines. Samba: 3.5.6 Ctdb: 1.0.112-12-1 Filesystem: glusterfs Sometimes i have the problem that some Office-Files are locked for other MS-Office-Users. If i try to access those locked files using linux(mount cifs and open it with openoffice) i can open it. I am not 100% sure, but it seems that i can open those files with office2003 too.

Superb. I'll take a look.
