I always used IET on CentOS but I have a quick server to setup to backup some VM's, then migrate to DAS on another server and the easiest way for me will be to accomplish this via iSCSI vmfs stores. I figured I would just use the ini that ships with CentOS but have never used it against ESX, anyone do this and have experiences they care to share? Should it be trivial or are there any non

Hi all, I would like to know if I could share some space on on of my servers, to another server(s) using the iSCSI protocal? I can see that CentOS can connect to an iSCSI server, but can it act as a iSCSI server? Is so, does anyone have some good HOWTO / tutorials / docs on how to set it up? I'm running CentOS 5.2 -- Kind Regards Rudi Ahlers

Hello, I have been using Xen now for several months and have been quite successful until attempting to utilize iscsi within my domU''s. My research has turned up many posts of people using iscsi with no problems, and I have found no others with the problem I seem to be experiencing. If this has been covered on this list in the past, please accept my humble apologies. Configuration:

I am trying to install Oracle RAC in a two node cluster for testing purposes, so performance is not something that concerns me. I just want to go through the process all the way to creating a database. I have all the prerequisites except the shared storage and thought I'd give this a try. I'm running: - CentOS 5.3 kernel 2.6.18-164.el5 - iscsitarget-1.4.18-1 -

Does anyone have any recommendations for the best way to bring up a iSCSI Target on a C5.3+ server ? Various blogs suggest compiling IET from source, but thats not real appealing to me (not that I can't do it, I just don't want to have to support it long term). I looked in rpmforge but didn't see anything.

Hey everyone, Is anybody aware of a /true/ active/active multi-head and multi-target clustered iSCSI daemon? IE: Server 1: Hostname: host1.test.com IP Address: 10.0.0.1 Server 2: Hostname: host2.test.com IP Address: 10.0.0.2 Then they would utilize a CLVM disk between them, let's call that VG "disk" and then directly map each LUN (1,2,3,4,etc) to LV's named 1,2,3,4,... and

Hello fellow sysadmins! I've assembled a whitebox system with a SuperMicro motherboard, case, 8GB of memory and a single quad core Xeon processor. I have two 9650SE-8LPML cards (8 ports each) in each server with 12 1TB SATA drives total. Three drives per "lane" on each card. CentOS 5.2 x86_64. I'm looking for advice on tuning this thing for performance. Especially for the

I am getting the following error on boot on a new install Centos 51: #/bin/sh ro no such file or directory then a kernel panic I have traced it to the call ''switchroot'' in the init script in the initrd. the exact same build without zen has no problems. the boot messages look like: Attaching to iSCSI storage iscsistart: transport class version 2.0-724. iscsid version 2.0-865

I was looking up on iSCSI in preparation and became aware that there are different iSCSI software/drivers/whatever-is-the-correct-term available. e.g. IET http://iscsitarget.sourceforge.net/ SCST http://scst.sourceforge.net/ STGT http://stgt.berlios.de/ LIO http://linux-iscsi.org/ Based on what I can see, it seems to be STGT because the site provides a link to Redhat advisory which seems to

I was wondering if anyone''s compiled a list of places to look to reduce Disk IO Latency for Xen PV DomUs. I''ve gotten reasonably acceptable performance from my setup (Dom0 as a iSCSI initiator, providing phy volumes to DomUs), at about 45MB/sec writes, and 80MB/sec reads (this is to a IET target running in blockio mode). As always, reducing latency for small disk operations

Hello all, I got some severe iscsi connection loss on my dom0 (Gentoo 2.6.20-xen-r6, xen 3.1.1). Happening several times a day. open-iscsi version is 2.0.865.12. Target iscsi is the open-e DSS product. Here is a snip of my messages log file: May 5 16:52:50 ying connection226:0: iscsi: detected conn error (1011) May 5 16:52:51 ying iscsid: connect failed (111) May 5 16:52:51 ying iscsid:

This idea is intruiging... Suppose one has a set of file servers called A, B, C, D, and so forth, all running CentOS 6.5 64-bit, all being interconnected with 10GbE. These file servers can be divided into identical pairs, so A is the same configuration (diks, processors, etc) as B, C the same as D, and so forth (because this is what I have; there are ten servers in all). Each file server has

Hi all. While playing with iSCSI Enterprise Target + multipathd on CentOS 5.1 (both the target and the initiator/multipath/xen box are Cent 5.1), I encountered a strange fault condition that leads to a kernel panic in a version of Xen 3.2.1-rc2 pulled from a couple of days ago. My lab consists of two Clovertown machines with dual GigE into separate switches. The target box is softraid5

Hi all, In threads posted by I believe Jonathan Tripley I promised to post my new XEN HA setup. Hope it can be of some use to some people. In this particular case I''m forced to use SLES 10SP3 with XEN 3.2, which excludes the possibility of using things like cLVM (which I don''t think I need anyway). So: Storage: I use two HP ML370 G5 machines with DRBD and heartbeat on

Greetings all. I need a transparent way of selectively controlling packet flow between two network devices such that for example I can "see" [e.g. tcpdump] a packet coming into eth0, queue it, and then manually release it out eth1, one packet at a time. See diagram below. (Reason for doing this is to watch the behavior of the device under test to certain packets but I cannot control

Has anyone succesfully setup, and used CentOS as an iSCSI server? I'm trying to setup a server with 4x500GB HDD's, setup in RAID 10 to act as an iSCSI server for a virtualization project, but I can't find a decent howto on how to setup an iSCSI server using CentOS. I would like to setup something like Openfiler, but we also need todo some other stuff that OpenFiler doesn't

DV suggested that we document some libvirt setups using shared storage. I'm not a fan of NFS, so I wrote some blog posts on how to use iSCSI in the context of libvirt + KVM. There is of course more than one way todo things, so I've outlined a couple of different options. One completely manual command line approach using tgtadm on the iSCSI server:

Dear all, I am trying to estimate simultaneous equation model concerning growth in russian regions. I run the analysis by means of FIML in R sem package. I am not familiar with SEM yet, but I've just got several suitable estimated specifications. Nevertheless, sometimes R gives the following warning message: Warning message: Negative parameter variances. Model is probably underidentified.

I made this change (not specifically changing from a list to a string, but changing from a hardcoded value to the value that was actually decided by cmake), and I checked that it works with cmake 2.8.12.2 which is the minimum version set in CMakeLists.txt. So if it doesn’t work with cmake 3.1/3.2 then that looks like something new that was introduced after 2.8.12.2. I’ll have a look at this
