Hi, I was reading the Clustered Samba Wiki and I noticed the following blurb about OCFS2 and Samba ( http://wiki.samba.org/index.php/CTDB_Setup#Other_cluster_filesystems). I was wondering if anyone can confirm that the "fileid:mapping" is or isn't required for OCFS2. I was also wondering if anyone would be willing to share their experiences with Clustered Samba OCFS2. Does it

A first start and introduction to CTDB you will find in the Wiki:

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 have set up a 2-node CTDB cluster serving NFS and CIFS authenticating Windows and Linux users via Active Directory. The setup works fine, except only one server in the CTDB-cluster is able to join the AD domain at a given instance. If you manually add the other server into AD, the already connected server gets disconnected. There is no specific error message logged in /var/log/message or

I''ve enabled "extended inode refs" and "skinny metadata extent refs" with btrfstune. Then, I''ve tried running "btrfs filesystem balance" - unfortunately it segfaulted. (not sure if I should run balance operation after using btrfstune with -r and -x)? This is with 3.10 kernel with "Btrfs: make backref walking code handle skinny metadata"

how to use iproute/iptables to balance by packet OUTBOUND traffic between 2 PPP (pptp cable modem and pppoe adsl modem) links to the same ISP . also by using the fact that the ISP dosen''t filter source IP address - meaning i can use either PPP''s link assigned IP address as the source IP in the ip header.., it works for both devices.., what i want to achive is : when uploading a

Hi All I have two asterisk servers in two different companies. I want both servers to use the same configuration. I.e. if I add an extension on server A I want this to be reflected on server B. This can be done using NFS or rsync. However this is not my main problem. My problem is as follows. Lets suppose I have the two servers and they are identical. If user A registers at Server A and User B

Hi everyone, I am using Dovecot 2.2 with dict SQL.

Hi everybody I'm trying to set up a high available (HA) cluster with samba and store the data on a SAN. Are there any known problems that I should no before starting this project? Have someone of you already realized a project like this? And which cluster-software did you use? Thanks for response Greets Chris

Hi, For a testing purposes I'm trying to create two node HA environment for running some service (openvpn and haproxy). I installed two CentOS 6.4 KVM guests. I was able to create a cluster and some resources. I followed the document https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Configuring_the_Red_Hat_High_Availability_Add-On_with_Pacemaker/index.html

Hi Folks, Following up a bit on the GFS vs. EVMS thread from last month... Hi Folks, I''m about to migrate from a dedicated RH9 server (mostly email, list serving, web serving) to a couple of new machines that I''ll be deploying in a colocation arrangement - with a lot more control over configuration. My current box is pretty basic - using RAID-1 and nightly backups to

After a extensive search about a tool or method to undelete/recover files deleted from a partition whit the ext3 FS, i want to make some comments about the use of this FS. What are the benefits of use the ext3 FS in a system (server, desktop, etc.) if i cant recover files deleted by an intruder if i want need to make forensics; or if i want to recover important files deleted (business, personal

We are planning to build an HA cluster of samba servers, using winbind to authenticate against an Active Directory domain. The problem I see with this, is that the Winbind uid mappings will not necessarily be the same on both nodes in the HA cluster. Does anyone have any suggestions on how to get the winbind uid and gid mappings to match on 2 separate servers? Alex Laslavic Havertys Tech

Hi all, I installed a Linux-HA-cluster with DRBD and Asterisk 1.4 on it. Actually it might work quite good, failover etc. works, even if this is not a 0-downtime solution, because current calls are dropped and the phones not are reachable until they reregister at the Asterisk. It "might" work good, because my phones are not able to register at the cluster-ip address, because the

Hello, I've been thinking about the best way to achieve load balancing and making my mail servers highly available. So far I believe I have 2 scenarios: Scenario1: This should allow any to lose any of the servers and clients still have access to their emails (although I am not sure how the indexes would react to this and sudden disconnection) - 2 Dovecot Proxy servers, using a
