There is a 3 nodes ctdb cluster is running.

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

Hi, I am recovering a CentOS 5.4 system. I've copied all partitions into the recovery system. I've installed grub boot loader. However, the original system is using /dev/sdb1 for root (/), while the recovery system is using LVM (/dev/vg0/lv1) for root (/). When recovery system boots, I got the panic error: * Mounting /dev/sdb1 on /sysroot * Mount: mounting /...

...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 noticed a "*High RECLOCK latency"* (of 4s) message in syslog, and just wanted to see if we could safely squelch the warning, and if so, how?

For some time now I have been puzzled as to why certain portions of my system boot were quite slow -- but only after journal recoveries. I was fearing that there was some ugly interaction between the recovery and the use of the journal shortly afterward but alas that is not the case. So just in case anybody else is seeing this problem and decides to try to hunt it down, let me save you some time. I am using an 0.0.6b ext3 kernel on a Red Hat 7.0 system. I was finding that if my system did not get shu...

Hello, at this time i want to install a CTDB Cluster with SAMBA 4.7.7 from SOURCE! I compiled samba as follow: |./configure| |--with-cluster-support ||--with-shared-modules=idmap_rid,idmap_tdb2,idmap_ad| The whole SAMBA enviroment is located in /usr/local/samba/. CTDB is located in /usr/local/samba/etc/ctdb. I guess right that the correct path of ctdbd.conf (node file, public address file

Many people have deleted the wrong file when the file has been accidentally lost, a lot of computer companies now have a data recovery business, but also set the price very high, not the individual can accept, in fact, data recovery is also dependent on A variety of data recovery software, as long as the master of the use of these software, we can get back some of their own deleted files. Data recovery software is also there...

I'm currently testing fail-over with a two-node active-active cluster (with node dig and node dag): Both nodes are up, one is manually killed. CTDB on the node that's still alive should perform a recovery and everything should working again. What's infrequently happening is: After killing the pacemaker-process on dag (and dag consequently being fenced), dig's CTDB tries to get the recovery lock and fails. As there is no other node online to get the recovery lock and thus finishing CTDB...

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 shared? What can be optionally shared? The doc is not clear on this...
