I have a trio of servers that like to reboot during high disk / network IO operations. They don't appear to panic, as I have kernel.panic = 0 in sysctl.conf. The syslog just shows normal messages, like samba complaining about browse master and then just syslogd starting up. The machines seem to crash when I'm not near the console, usually when I'm trying to pull data off them to

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

Does anyone know off hand how to bind iscsi enterprise target to two distinct addresses. Lets say I have a machine that has a bunch of interfaces on it, with different subnets. Rather than have ietd broadcast itself on all interfaces (the default), I would like to limit it to only two interfaces. I have edited the init.d startup script with --address x.x.x.x which works, but I tried using the

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

Has anybody tried or knows if it is possible to create a MD RAID1 device using networked iSCSI devices like those created using OpenFiler? The idea I'm thinking of here is to use two OpenFiler servers with physical drives in RAID 1, to create iSCSI virtual devices and run CentOS guest VMs off the MD RAID 1 device. Since theoretically, this setup would survive both a single physical drive

Hi, I am doing a test setup of 11G RAC, and I am using Jeff Hunter's document to achieve this. I have 3 nodes all running Linux Redhat 4 htsscsun06-openfiler htssclin5 htssclin4 I have created the Logical Volumes on htsscsun06-openfiler - fdisk -l shows fdisk -l Disk /dev/hdb: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of

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 -- +-=====---------------------------+ |

Hello, I need to setup a NAS server on Centos. The machine will be: Dual xeon/Dual Opteron 4GB memory 13x 320GB SATA + 1 hotspare 1x 320GB SATA for OS The server can do RAID5,6,or 10. Has anyone installed such a software and can you recommand a specific product? Thank you.

Hi all, I need to install a virtual machine acting as a virtual storage server under CentOS 5.x (using kvm, xen, virtualbox or vmware). This virtual storage machine needs to server storage to another ESXi server and at the same time to the host where is installed. This is due to the limitations of hardware I have available. Both hosts needs to server several machines. It is very

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

> Simple, it's only a NAS device, and not really a file server / web > server / data base server as well. 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

I''ve been doing a lot of reading about ZFS lately, and I''m quite enamored of its design goals. The reliability considerations are particularly attractive, and the snapshot scheme is more robust than anything I''m familiar with. I would very much like to keep my personal data in such a filesystem. Some time ago, I caught the launch of Drobo, a USB-connected box that does

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

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

Hi: I need advice on implementing a storage server. I really do not have the $ to spend for a Dell iSCSI storage divice and I am thinking trunning CentOS 5.x with ftp or FreeNAS. Here is what I am looking at and concerned about. Situation: My current storage needs are approximately 1.5 TB annually. This will increase to about 3.5 TB annually over the next 5 years (rough est.). This box

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

I have two servers with identical hardware ... TYAN i3210w system boards with dual intel gigabit interfaces, and a PCI intel gigabit nic. I'm running Centos 5.4, x86_64, 2.6.18-164.6.1.el5 Every other time I reboot, the nics initialize in a different order. anaconda had setup /etc/modprobe.conf with alias lines for the cards: alias eth0 e1000 alias eth1 e1000e alias eth2 e1000e However,

Hi all, some results from my configuration. I''ve this configuration (I''m not interested in raw top performances but in reliability.. so, I can accept slow MB/sec and prefer to rely on a RAID6, for example): 1 Infortrend iSCSI Array A16E-G2130-4 with: - 1GB DDR cache - RAID6 - 7 x 500GB sataII Seagate ST3500630NS with 16mb (no budget for SAS) - one of the logic volumes (about

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
