I was just curious to what your redundancy solution is. I have considered many options, so I thought I would share and get an idea for what others are doing. My setup is two different locations with a 10MB WLAN fiber link between the two. Each location has it's own PRI as well. I have considered and tested many options this last year or so. 1) Using hearbeat and drbd to monitor the

Hi, I''ve been building up a new HA system, running Xen on DRBD devices. Configuration this applies to: Debian Lenny xen-linux-system-2.6.26-2-xen-686 package |**|drbd8-modules-2.6.26-2-686 drbd8-modules-2.6.26-2-xen-686 As I''ve been building the system, I ran into an interesting problem, with two symptoms: 1. running VMs would come back up after a reboot, but would hang on

I am considering couple options of converting a current service into a HA using multi servers or any other solutions. The point is that I am thinking about the options and which I am looking for. NFS can be a storage which has it's own pros and cons. There is the option of DRBD but as of now it's limited for two hosts. What options do exist out-there as a solution? The main issues are

I know this thread has been discussed before, but I have run into this problem and would like to re-open it... I have come to a point in my project where I need to provide an import/export feature for Active Records. Since a user could export off one system and import onto another auto-increment integers will not work (collisions on ids due to lack of uniquness). Listed below is an initial list

Hi everyone, I could have posted this on R-devel or the GUI list, however don't feel it's that serious. Hence, decided R-help would be the most appropriate. I'm not so much interested in which is the best user interface for R. Rather which is the best ***platform*** for developing ***new*** user interfaces for R. Noting I'm using the term user interface is a very general sense.

Ubuntu 14.04, drbd Hi On a drbd Primary node, when attempting to mount our cluster partition: sudo mount -t ocfs2 /dev/drbd1 /cluster we get: mount.ocfs2: Unable to access cluster service while trying to join the group We then call: sudo dpkg-reconfigure ocfs2-tools Setting cluster stack "o2cb": OK Starting O2CB cluster ocfs2: OK And all is well: Aug 22 13:48:23 uc1 kernel: [

Hello Everyone, Does anyone have any insight into the DWR library (http://getahead.ltd.uk/dwr/index)? I want to know the pros/cons of using DWR Vs Prototype/Scriptaculous libraries. I am a great fan of the prototype/scriptaculous combination and have been working with them for the last 3-4 months but for some reasons I have been asked to look into DWR. Due to it''s tight integration

Hello, I'm beginning to give up on making Linux-HA's heartbeat work for my environment (CentOS x86_64) and am wondering what other option have I got to help me: 1. Use IPVS to maintain a cluster of virtual servers, either master/slave or load-balanced. 2. Use DRBD in master/slave fashion to keep a home-grown application highly-available. The first thing I stumbled upon is RedHat Cluster

Hi all I'm looking for a working HOWTO / Tutorial / sample setup of setting up a clustered email server. I know I can setup a CentOS cluster with Heartbeat & drbd, but I'm not 100% convinced it will work for the email as well. Ideally, I'd like to use an open source groupware server, like say open exchange, php groupware, Scalix (free / community version), etc. So, if anyone

Does anyone here on this list have experience with HA clustering? I'm previewing drbd as a potential tool, and wanted to know if anyone here has experiemented with it at all... How stable is it? Does the additional likelyhood of failure given the additional complexity actually get compensated by a better overall system? http://www.drbd.org/ Any feedback is welcome... -Ben --

Hi all. Currently I am administering a mail cluster in which messages are stored on software RAID shared with NFS. There are several NFS servers, every one of them exports a part of all mail files for a specific frontend with postfix. We are thinking about replacing these storage hosts with one solution, maybe a storage array with appropriate disk space and I/O capacity. What are pros and cons

I am using the version of wine that came with RedHat 7.2. I just noticed that Codeweavers has their own distribution of wine that includes what looks like a convenient setup configuration utility. What are the pros and cons of uninstalling what I got from RedHat and downloading and installing the rpm from Codeweavers? Thanks

I have some questions about whether I should set up folders under INBOX vs. having them outside the INBOX namespace. I'm setting up a new Dovecot 2.2.0 on an Ubuntu 12.04.2 server. My plan is to move my users (family members) to this new server from an old Cyrus server. Everybody is currently using (and will continue to use) IMAP, and either Thunderbird or SquirrelMail as their e-mail

Hi all, Where i want to arrive: 1) having two storage server replicating partition with DRBD 2) exporting via GNBD from the primary server the drbd with GFS2 3) inporting the GNBD on some nodes and mount it with GFS2 Assuming no logical error are done in the last points logic this is the situation: Server 1: LogVol09, DRDB configured as /dev/drbd0 replicated to Server 2. DRBD seems to work

Note: here is a post we sent to the openSUSE list which we'd like to share here. Cheers. Hi everyone Next month we hope to go into production with our drbd-ocfs2-ctdb cluster. Of course, we must prove to our boss that it is a fair if not better replacement for our single AD domain file-server which it will replace. A few questions remain to which we cannot find a simple answer that a non

Apart from religious grounds (!), is there any pros or cons why I should choose one over the other for a new install of asterisk ? Julian

I was wondering what could be pros and cons of ztdummy vs proper timer device (i.e. X100P). I am going to set up an asterisk server in europe (to do trunking, to save bandwith) and I was wondering if it'll be OK to get it going with ztdummy. Furthermore, I have only a 1024/256kbps PPPOE DSL link and I need to squeeze 12 channels through, I was wondering which codec would be suitable
