CentOS 5 :: Conga Errors With Enabled Shared Storage Support In CentOS 5.3?
Jun 24, 2009I try to set up a 5 nodes cluster and a shared Coraid Storage with conga but it fails with "Shared Storage Support" checked.The message is:'A problem occurred when installing packages: Packages of set "Clustered Storage" are not present in available repository' and it is shown under every node on the next sceen after I submit.The pc where conga runs is on the same subnet (192.168.xxx.xxx) and it has the same /etc/hosts of the other nodes.In that pc runs a proxy too and the nodes go out through it (that pc has 2 NICs)Every node (2.6.18-128.1.14.el5-xen-x86_64) is patched whith the last yum update (this morning) the same is for the pc (2.6.18-128.1.14.el5).Every node has 4 NICs , 2 NICc towards the storage the others in bonding towards the WAN.Every node is exactly alike, they have been installed with the ks.cfg generated from the first node and they all have the support for Clustering, Virtualization, and Clustered Storage.

Mar 30, 2011I Have 10.04 LTS I want to make a more secure storage with 3 PATA 300GB disks. I think a raid5 is the best. I don't need to boot or have a system on the storage volumes.i have find some guides, but they are for raid on system-disk and make them bootable, and seems to be to complicated for me.
I have made ext4 volumes on them and flaged them as raid in gparted.

Dec 26, 2010I'm using centos 5.5,my problem is that i need to disable usb-storage in my machine.But i need usb mouse and usb keyboard to function properly.I have tried all the below mentioned methods,
1.Appending blacklist-usbstorage to /etc/modprobe.d/bl*
2.removing the *.ko file,which removes the usb-storage drivers.
3.Added the line, install usb-storage /bin/true to /etc/modeprobe.conf
The first mentioned method works partially.That is the usb port in the front panel of the cpu is gets disabled.But,when i insert it at the port behind the CPU, usb-storage(pendirve) mounts automatically,which should not happen.
NOTE:usb-storage have to be disabled only for normal-users
Ubuntu Servers :: Mainboard And Storage System - How Both Storage Devices Will Be Supported By Debian
Mar 11, 2011I'm interested in buying a new hardware for my company. The old server (now 10 years old) should be replaced with a new one. Till now, I was looking on different hardware suppliers, boards and different other places. I found a Tyan board [URL]. The hardware spec is quite interesting and the board would fullfill our claims.
how both storage devices will be supported by Ubuntu or Debian??
- SATA-Controller: AMD SP5100
- SAS-Controller: LSI 1068E
Server :: Creation Of Clustered Storage On CentOS 5.5?
Sep 25, 2010What I am trying to to is set up a cluster as follows:
- There are four nodes
- Nodes three and four have large amounts of storage that will be used for storing user data.
- Nodes one and two will be running a couple of network services.
I'd like have nodes one and two to have a clustered filesystem just between them to store data for the services run only by them.is it possible to share one filesystem between two nodes and another filesystem between two other nodes? The cluster seems to try to make the storage changes across all nodes. They will not be able to spend the extra money to get the same storage in all four nodes. Here is what I have done. I am using CentOS 5.5. After installing CentOS, I did this:
On all nodes:
Code:
[root@node1 ~]# yum groupinstall "Clustering"
[root@node1 ~]# yum groupinstall "Cluster Storage"
[root@node1 ~]# chkconfig ricci on
[code].....
...which I think makes sense because the cluster was supposed to create the PV and the volume group, but did not. I don't even think it tries. The first time it tries to do anything to another node is when I create a logical volume.
CentOS 5 :: Migrate VM In A Non Shared Storage Environment?

Jun 21, 2011We new have server with VmWare ESXi4.1 and we created virtual machine with CentOS5.6.This CentOS5.6 virtual machine will be used as webserver. We need to backup all files and have access to these files. We are going to keep all websites, databases, backups on data storage (NetApp FAS2000 series).
We have two options to how to use this storage:
1: We can mount storage volume directly to CentOS5.6 by NFS.
2: We can add storage via NFS to VmWare and then add new virtual disks to CentOS5.6 by VmWare vSphere client.
What option would you recommend to use? Which option is better, faster and more secure? My thoughts:If we mount storage volume directly to CentOS5.6 so we can access .snapshot directory there is all snapshots. So it's easy to access all backed up files. NetApp has snapshot system and we can schedule to make snapshots automatically, so we don't need to setup any additional backup utilities in CentOS5.6. But we don't have any NetApp snapshot restoring software license so copy/paste from .snapshot directory is only option.
If we add storage to VmWare firstly (by NFS) and then add new virtual hard disks to CentOS5.6 by VmWare vSphere client so we have to setup rsnapshot(or any similar utility) to make backups in CentOS5.6. But NetApp will also make backups of .vmdk files. So it's like double backups, lol :) If storage crashes so we screwed in both ways, I think.
CentOS 5 :: 5.5 Hangs When Copying Files To Storage
Sep 7, 2011I built a centralized storage system a year ago (Aug. 2010) and for the past 10 months it has preformed flawlessly. About two months ago (July 2011) I began having problems writing to my centralized storage. The copies (cp -rpv) fail whether they are nfs or samba mounted disks to my centralized storage.
Attempting to copy either frame sequence (.dpx, .tiffs, .targas) or .MOV files now lock up my system and knock my storage offline.
The error that continues to echo back when this happens is :
I have not made any changes or updates to my storage configuration since building it last August 2010. I have reached out to Areca, and they found nothing wrong with the Raid Controller or my Raid settings.
I tried to troubleshoot all the basics - swapped out cables, replaced the WD storage disks, changed switches still the problem persists.
If anyone else has experienced this issue please let me know what you did to fix it. I can also post any error logs or message logs if that would be of assistance.
Below are the specs of my storage system
CentOS 5 Server :: Create GFS Shared Storage Without SAN/iSCSI
Sep 3, 2009I built a CentOS 5 Linux cluster with GFS storage using local RAID volume and share it with gnbd_export/import on two web-servers. Now I need to expand that storage to another servers local volume. I saw the picture in the manual, but I don`t know, how can I create that scheme.
I can use gnbd_export on the second server and gnbd_import on the first. In that case I will have two volumes on the first storage and I can expand volume group, logical volume, etc on it.
CentOS 5 Server :: Centralized Storage For Windows And Clients?

Windows users are getting authenticated through server as Primary Domain Controller and Linux clients directly from Openldap directory. But I have little problem that is I want to mount home folders created on server to be available on clients so clients get a centralized storage with some quota on both Linux and Windows clients. Can you help me please how can I do that.

Jul 8, 2009I am working on the beginning of implementing a two-node cluster with shared storage (GFS) and IP address. Both machines are virtual on VMware ESX 3.5, that should not make a difference, but that is the background.current status is that I have a single node cluster built with only the IP address configured within the cluster. The issue that I am having is that I have configured a service to contain only the IP address resource, however, when I go into cluster management that "service" does not register. As such, I cannot bring it online, ping it, etc. below is my cluster.conf configuration:

CentOS 5 Hardware :: Direct Attached SCSI Storage Not Showing Up In O/S
Oct 14, 2009We just setup a HP DL380 with CentOS 5, and ran all of the latest updates.I am trying to attach a Compaq array (no model number) that is SCSI attached. I can see the array from the bios and created a raid group on it from there. However, from LVM and lvscan, I don't see it at all. I checked dmesg and there are no errors.Also, interestingly /proc/scsi/scsi is empty.
View 1 Replies View RelatedCentOS 5 :: Connect Up Servers To Storage Array Which Is Running As An SRP Target?
Jul 13, 2011My goal is to connect up a bunch of CentOS 5.6 servers to storage array which is running as an SRP target. These servers will be running eventually as Xen hypervisors. I'm using Mellanox Infiniband cards and a Qlogic Infiniband switch.
OFED drivers are already installed as standard. I have done the following.
1. Base install of CentOS 5.6 X86_64
2. Installed the following packages...
openib
ibutils
srptools
infiniband-diags
opensm
[Code]...
It works perfectly and connects to the target immediately with great results. I'd just like this to happen correctly on startup.
To work around the issue I have added the line srp_daemon -e -o into the init script for opensm /etc/init.d/opensmd but it doesnt always start the srp_daemon process. Its rather hit and miss
I'd really like srp_daemon to run as a service with a proper init script but I wouldnt know how to write one. I understand that this issue has been addressed in the RHEL6 srptools package but that doesnt help me because the software I intend to use on these servers specifically requires 5.
CentOS 5 Server :: Building VMWare Virtual Machines From CentOS Mail Servers?
Oct 12, 2010I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?
