Hello, We are using CTDB / Samba to serve a number of windows users, at this point around 1200. We have a 4 node CTDB setup. CTDB version - ctdb-1.0.114.7-1 Samba Version - sernet-samba-4.1.16-10 In recent months we've seen a big problem when 1 of the CTDB nodes is stopped or disconnected either manually or resulting from a problem. On some occasions, all other nodes get banned if a node

Hello, I've got a two node CTDB/Samba cluster that I'm having trouble with trying to add back a node after having to do an OS reload on it. The servers are running CTDB 2.5.1 and Samba 4.1.4 on AIX 7.1 TL2. The Samba CTDB databases and Samba service work fine from the node that was not reloaded. The rebuilt node is failing to re-add itself to the cluster. I'm looking for

Hi, I am setting up a two node Samba cluster with CTDB in AWS in two different subnets. All IP ports are open between these two subnets. I am initially forming the Samba cluster with one node, then will add the second node after startup of CTDB. I am not using public_addresses for CTDB due to AWS not supporting VIP's. I am using 64bit Amazon Linux with two NICs defined, eth0 as the

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

Can anyone help with some pointers to debug a problem with Samba and CTDB with smbstatus traversing the connections tdb? I've got a new two node cluster with Samba and CTDB on AIX. If I run smbstatus when the server has much user activity it hangs and the node it was run on gets banned. I see the following in the ctdb log: 2014/10/29 11:12:45.374580 [3932342]:

CTDB Samba Team, I have a two-node cluster successfully running a GFS2 filesystem. I compiled ctdb ver 1.12 with Samba 3.6.3 for 64-bit systems. Running on RHEL 5.7. I was able to add the cluster to the domain but after I restarted CTDB, it panics right after doing a vacuum of the serverid.tdb database. The lock file is on the GFS FS so both nodes can access it. Any ideas as to what

Hello, i'm still trying to find out what is the right path for ctdb.conf (ubuntu 18.04, samba was compiled from source!!).

Hello list, We know that CTDB uses lockfile in the cluster file system to prevent split-brain. It is a really good design when all nodes in the cluster can mount the cluster file system (e.g. GPFS/GFS/GlusterFS) and CTDB can work happily in this assumption. However, when split-brain happens, the disconnected private network violates this assumption usually. For example, we have four nodes (A, B,

Thanks Martin! We are using the ctdb 4.6.10. Are you able to recreate this every time? Sometimes? Rarely? Rarely. Note that you're referring to nodes 1, 2, 3 while CTDB numbers the nodes 0, 1, 2. In fact, the situation is a little more confused than this: This is my wrong. The CTDB numbers the nodes is 0,1,2. # ctdb status Number of nodes:3 pnn:0 10.231.8.70 OK pnn:1 10.231.8.68 OK

Yes, Please start with telling the running OS and samba version and an output of smb.conf And it looks like : https://bugzilla.samba.org/show_bug.cgi?id=13168 Increase the loglevels and post these also when you answer above.

Martin, I have checked more logs. Before ctdb-eventd went away, system memory utilization is very high, almost 100%.
