similar to: Getting CTDB dbstatistics in csv format?

Thanks, I'll do that. It might be a week or two. But I have solid C skills going back 25 years, and spent a decade doing C++. Let me know if there's a "getting started guide" for developers on the Samba project. Key tools to install, etc. I will need to spin up a VM to work in. Also, should chat with the CTO so he's aware.

Running into problems configuring different locations for the volatile and other database directories. Can someone provide a quick sanity check on what I'm doing below? Thank you.

This turns out to be an SELinux issue. Does anyone know the proper commands to restorecon or otherwise to set the SELinux policy for persistent/volatile database files moved to a different directory? Martin or Amitay? On Wed, Nov 4, 2020 at 9:02 AM Robert Buck <robert.buck at som.com> wrote: > Running into problems configuring different locations for the volatile and > other

Hello Everyone! Here's what I'm trying to do. I'm working on generating occurrences of precipitation based upon precipitation occurrence for a station during the previous day and two stations that have already been generated by joint probablities and 1st order Markov chains or by the same generation process. This has to be done for each remaining stations for each month. > genmat

Hi Team, I'm working on a CTDB Prometheus Exporter. I have two questions... First, does anyone have an "internal" cheat sheet on the metrics and their descriptions?

Hi Martin It seems as though, when I go from `clustering = no` to `clustering = yes`, if I do a domain join, it will fail. However, if I do a `systemctl restart ctdb` (knowing full well it will fail every time), if after this I add a sleep(15), then do a domain join, then do a `systemctl restart ctdb`, then the join will have worked, AND CTDB will start properly. So in a nutshell, in Ansible, -

Hi I have a question regarding CTDB RecLockLatencyMs tunable parameter. Is there any relationship between the RecLockLatencyMs property and the RecoverInterval property? Does one need to be larger than the other? Or if RecLockLatencyMs were increased to 5000ms, should some other setting be changed in proportion? We're using a geo-distributed etcd cluster for the CTDB recovery lock and I

Superb. I'll take a look.

Could I impose upon someone to provide some guidance? Some hint? Thank you Is a shared file system actually required? If etcd is used to manage the global recovery lock, is there any need at that point for a shared file system? In other words, are there samba or CTDB files (state) that must be on a shared file system, or can each clustered host simply have these files locally? What must be

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?

Very helpful. Thank you, Martin. I'd like to share the information below with you and solicit your fine feedback :-) I provide additional detail in case there is something else you feel strongly we should consider. We made some changes last night, let me share those with you. The error that is repeating itself and causing these failures is: Takeover run starting RELEASE_IP 10.200.1.230

We've only seen this error once, just occurred. We were having domain join issues.

I am having trouble adding a node to the selection DAG (e.g. during combine) E.g. node1 -> use1, use2 Now if you add a node2, with node1 -> node2 with node2 number of output values equal node1 number of output values, then combine as well as e.g. promotion pass with replace all of node1's uses with node2, leaving node1 dead. While this is kind of expected, does this mean a) always

Folks, We use a Golang-based lock tool that we wrote for CTDB. That tool interacts with our 3.4 etcd cluster, and follows the requirements specified in the project. Question, does the external command line tool get called when LMASTER and RECMASTER are false? Given a scenario where we have a set of processes that have it set to false, then others that have it set to true, does the locking tool

Thank you, Martin. Yes, we happen to be using Samba and CTDB v4.10.7, on Ubuntu. *Would these happen to include the defect?* *In your opinion, will 4s be an issue?* We happen to be running this on top of a geo-distributed etcd cluster, and in this particular case there was about 4200 miles between the two data centers. We're running a distributed NFS file system over a total of three data
