CTDB over WAN Link with LMASTER/RECMASTER Disabled
Hi, I came across the 'CTDB_CAPABILITY_LMASTER=no' and 'CTDB_CAPABILITY_RECMASTER=no' options in my quest to salvage a rather poorly performing CTDB cluster over Ceph(fs). Unfortunately, the docs provide not enough information for a clustering noop like myself. Would there be any benefit to disabling those options for a branch office node on a high-latency WAN connection?

CTDB question about "shared file system"
Very helpful. Thank you, Martin.

CTDB question about "shared file system"
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

CTDB and nfs-ganesha
Hi there ? I seem to be having trouble wrapping my brain about the CTDB and ganesha configuration. I thought I had it figured out, but it doesn?t seem to be doing any checking of the nfs-ganesha service. I put nfs-ganesha-callout as executable in /etc/ctdb I create nfs-checks-ganesha.d folder in /etc/ctdb and in there I have 20.nfs_ganesha.check In my ctdbd.conf file I have: # Options to

Glusterfs/CTDB/Samba file locking problem
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, [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.

CTDB+GFS2+CMAN. clean_start="0" or clean_start="1"?
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

ctdb samba and winbind event problem
Hi to all, I'm having a CTDB-Cluster with two nodes (both Ubuntu wit Sernet-packages 4.17.4). Now I want to replace one of the nodes. The first step was to bring a new node to the CTDB-Cluster. This time a Debian 11 but with the same sernet-packages (4.17.4). Adding the new node to /etc/ctdb/nodes at the end of the list. And the virtual IP to /etc/ctdb/public_addresses, also at the end
