Dear R users, I'm estimating a two-level regresion model but having difficuly in finding a good R syntax example. Let me use an example to explain what I'm doing. The dependent variable is math score (mathscore). Predictors are at two levels. At the student level, they are household income (hinc) and IQ (IQ). At the school level, there is a dummy variable indicating if the school is a

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Up until now, I have been using drbd for file custers with great success. Yes, it is a PITA, and sometimes you can get annoying sincronization issues (mostly on lab situations). Now I have been considering giving gnbd (with cs/gfs) a try. Do any of you ever crossed this path ? Any comparisons or comments ? TIA, - -- Rodrigo Barbosa "Quid

Hi all, We're looking at deploying a small Xen cluster to run some of our smaller applications. I'm curious to get the lists opinions and advice on what's needed. The plan at the moment is to have two or three servers running as the Xen dom0 hosts and two servers running as storage servers. As we're trying to do this on a small scale, there is no means to hook the

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

Hi everybody, as discussed and agreed at the Cluster Summit we need to split our tree to make life easier in the long run (etc. etc.). We need to decide how we want to do it and there are different approaches to that. I was able to think of 3. There might be more and I might not have taken everything into consideration so comments and ideas are welcome. At this point we haven't really

Hi all, I am using heartbeat and drbd on CentOS 5 (see http://www.centos.org/modules/newbb/viewtopic.php?topic_id=7816&forum=41 for details).. DRBD and heartbeat are working, and now I want to put GNBD on top on this. However, I installed the latest CentOS-plus kernel (2.6.18-8.1.8.el5.centos.plus) but there doesn't appear to be a kmod-gndb for this kernel. Looks like the latest

Any thoughts on running Xen on OpenSSI? We have an app we''d like to cluster but is expressly and completely incompatible with the OSes that OpenSSI are supported on, but if we can run several Xen domains on a cluster we can run those OSes and, naturally, that app. Thoughts?

Hello there! I made Debian, Xen 2.0 and CLUSTER/GFS work together :). I wrote this little tutorial to help you setup yours. Any feedback is welcome, except comments about W3C validation of my code :p Note that I am talking about compiling CLUSTER with your XEN kernel, I don''t explain how to setup a working cluster. You can find how to setup those in official RedHat docs. You will see,

I am considering building a pair of storage servers that will be using CentOS and GFS to share the storage from a Coraid (SATA+Raid) EtherDrive shelf. Has anyone else tried such a setup? Is GFS stable enough to use in a production environment? There is a build of GFS 6.1 at http://rpm.karan.org/el4/csgfs/. Has anyone used this? Is it stable? Will I run into any problems if I use CentOS 3.5

Hey all, I''m thinking about moving my 2.0.7 install over to 3.0.0 for eventual use in a production environment. Two questions: 1) Do people think 3.0.0 is ready for production - or is it just a testing/unstable playpen? 2) What do I have to change - just the xen-2.0.7.gz for do I have to recompile the dom0/domU kernels too? Cheers, Matthew Walster

Hi all I tried to run bonnie++ disk stresser in dom-U, who''s disk is backed with non-local (on nfs) loop-back file. The machine rebooted pretty quickly. So, how do I tell what''s barfing? Is it Xen? Is it dom-0 (nfs or loop-back)? I looked in dom-0''s /var/log/messages and didn''t see any obvious record of a dom-0 whoopsie (but is that the right place to look

# grub.conf generated by anaconda I recently tried installing xen on another machine and I''m getting the "CPU0 is toast rebooting in 5 seconds" message. Reading through past postings, I was hopeful setting the dom0_mem=128M would solve the problem. Unfortunately, it didn''t make a difference. I haven''t fooled with anything on this system -- just a fresh FC4

I want to thank everyone who has provided insight into my thread about clustering MySql. I kind of just sat back and watched it develop. I learned a lot from it all. I have been reading all of the documentation on clustering provided by Centos/Red Hat, and find I travel in circles. I read one chapter and answer a self-imposed question but I end up asking myself another. What I really want to

Hi, I am currently testing Xen on my laptop and was wondering if there was any way to enable ACPI sleep so that I can resume sessions when I''m on the go. Is this possible?

I''ve been brainstorming... I want to create a 2-node HA active/active cluster (In other words I want to run a handful of DomUs on one node and a handful on another). In the event of a failure I want all DomUs to fail over to the other node and start working immediately. I want absolutely no single-points-of-failure. I want to do it with free software and no special hardware. I want
