similar to: CentOS MD RAID 1 on Openfiler iSCSI

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

Here is something I am currently lokoing at, and wondering if you'd considered it or if anyone here has done it. I've got a bunch of existing hardware - really good IBM stuff that is all installed with CentOS (with a few exceptions). We want to move to virtualization, but

Greetings list friends, Just wondering if anyone is using openfiler with Xen or XCP? If so how has the experience been? Any particular points to keep in mind? thanks, CJP _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I finally figured out my mistake creating the raid devices and got a working RAID 0 on two RAID 1 arrays. But I wasn't able to add another RAID 1 component to the array with the error mdadm: add new device failed for /dev/md/mdr1_3 as 2:

Two questions (and then a bonus one), kind of interrelated, but, first, some basic info. I'm using OCFS2 on OpenSUSE 10.2, kernel 2.6.18.8(-0.7). There are three nodes in the OCFS2 cluster, backed by Openfiler iSCSI storage. First, I'm using Openfiler and iSCSI volumes to back my OCFS2 file system. The nodes that are part of the OCFS2 cluster use the file system as a shared storage

Hi, I'm looking at using Linux as a NAS / SAN device, and would like some input from other's who have done this before? How would it compare to commercial SAN devices, Thecus N8800SAS (http://www.thecus.com/products_over.php?cid=11&pid=177&set_language=english) or something similar to these? I would probably use hardware RAID 10, and could go with either SAS / SATA, and then

Is it possible or will there be any problems with using mdraid on top of mdraid? specifically say mdraid 1/5 on top of mdraid multipath. e.g. 4 storage machines exporting iSCSI targets via two different physical network switches then use multipath to create md block devices then use mdraid on these md block devices The purpose being the storage array surviving a physical network switch

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

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, We are going to buy some NFS storage for 6-8 VMs on a single host, but want to expand to a second host. What storage recommendations would you give if you have between 2000 and 5000 USD? How about nexenta? what hardware would you use? any vendor? Experiences with openfiler and opennas? Thanks for the responses. Daniel -- +-=====---------------------------+ |

Hi, I am doing a test setup of 11G RAC, and I am using Jeff Hunter's document to achieve this.

Hey folks, I don't seem to be able to get a response from the openfiler forums (and they want 40 quid for the fine manual!), and since there has been a lot of chat about it here lately, I figured I'd ask here. Please forgive my terminology as I am just making my first baby steps into iSCSI and Fiber Channel, and am not very well read on the matters. So I could be using the wrong terms

I was trying to do some performance testing between using iSCSI on the host as a diskfile to a guest vs the VM guest using the iSCSI device directly. However, in the process of trying to establish a baseline performance figure, I started increasing the MTU settings on the PCI-express NICs with RTL8168B chips. First bottleneck was discovering the max MTU allowed on these is 7K instead of 9K but

Hi all, I have the strangest problem on one of our backup server. iscsi doesn't start at all, and gives the following error: [root at 2U-NAS ~]# /etc/init.d/iscsi status iscsid is stopped [root at 2U-NAS ~]# /etc/init.d/iscsi start iscsid is stopped Starting iSCSI daemon: Unable to create pid file: /var/run/brcm_iscsiuio.pid [FAILED] Setting up iSCSI targets: iscsiadm: No records

Hi, How do I setup multiple password protected iSCSI targets on Linux? I know that mounting a password protected iSCSI target requires modify these records with the appropriate values: node.session.auth.username = My_ISCSI_USR_NAME node.session.auth.password = MyPassword discovery.sendtargets.auth.username = My_ISCSI_USR_NAME discovery.sendtargets.auth.password = MyPassword But, now I need

Hi, I would like to get some input from people who have used these options for mounting a remote server to a local server. Basically, I need to replicate / backup data from one server to another, but over the internet (i.e. insecure channels) Currently we have been mounting an SMB share over SSH, but it's got it's own set of problems. And I don't know if this is optimal, or if I

Anyone running centos with an iscsi filesystem mounted? If so: What version of centos? Which iscsi package? What filesystem are you using on the mount? Does it perform like you'd expect? Thanks, peter

Good day, everyone. I have SAN server build with Openfiler OS, with iSCSI mode turned on. I have two nodes, which connect to that server via iSCSI, using one of two active iSCSI partitions. I've installed ocfs2 1.3.3 with kernel 2.6.23.1, configured it, made ocfs2 partition and was successful in mounting it on both nodes. Everything works just fine, I can upload file from one node and

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
