General :: Disable Only Usb-storage In Centos 5.5?
Dec 26, 2010
I'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

I am trying to disable USB storage from servers.What I did is as following1> modprobe -vr usb_storage2> blacklist usb_storageIt is working fine. But root can again load the module into the kernel. [ modeprobe -v usb_storage ] want to restrict this also. My requirement is not even root can access the usb storage.

I've got a problem with my 3G modem [Huawei E122].
It has internal storage and kernel assigns a device [/dev/sdX] to it.
Because of that, every second time my machine will not boot - kernel panic - as my usb hdd gets assigned /dev/sdb instead of /dev/sda.
I cannot use LABEL nor UUID in root= kernel parameter, as it is only available when using initrd, and I can't use it - I am using Debian on my router - mips architecture machine.
I have to prevent this from happening, as my router has to start everyday and I have to be sure it works ok. I don't have physical access to restart it when something goes wrong.
I don't use my modem internal storage, there's no SD card inserted. However kernel detects the reader and loads it.
I can not prevent loading od usb drivers since my hdd is on USB as well.

I would like to know a way to disable the usb storage capability of the clients computers on a LAN, running opensuse 11.2.
-- I tried the modprobe -r usb-storage , but nothing happend
-- I tried the nousb option when loading the kernel, it worked, but mouse which was connected through usb port was also disabled
-- Also there is no usb-storage.ko driver inside the /lib/modules/2.6.31.12-0.2-desktop/kernel/drivers/usb/storage folder... there isn't the storage folder itself

I want to disable usb storage module on Ubuntu 8.10. I also have Ubuntu 9.10 and when I put
blacklist usb_storage
in /etc/modprobe.d/blacklist.conf everything is fine.
When I do the same in 8.10 nothing happens. The difference is that there is
/etc/modprobe.d/blacklist

I work for a regional cell phone company, and have recently taken it upon myself to create some documentation that will aid our mobile broadband users with installation of the aircards we carry.I decided to start out with Ubuntu 9.10, and I am using a Novatel mc727. I set it up using the mobile broadband feature that is built in, but I am having a few problems. First I have noticed that once you get the connection created, if you try to edit the settings, an error pops up stating that you are not authorized to do so, before I even get a chance to put in the password. Its not really a big deal, and if it comes down to it you can always delete the connection and start over. However, I have noticed that with the card plugged in, sometimes it can take up to 15 minutes to be recognized as a connection. I got to thinking about it and figured it may have something to do with the fact that this card, and all the cards we carry are seen on windows as a mass storage device. So to test this, i left the card in and rebooted, and of course on reboot, the card was mounted and once i hit eject, it was seen as a modem right away.

I want to disable mounting usb storage devices except some devices based on its vendor id. I tried by adding below udev rule in debian wheezy
Code: Select allACTION=="add", SUBSYSTEMS=="usb", RUN+="/bin/sh -c 'for host in /sys/bus/usb/devices/usb*; do echo 0 > $host/authorized_default; done'"
ACTION=="add", ATTR{idVendor}=="054c", RUN+="/bin/sh -c 'echo 1 >/sys$DEVPATH/authorized'"
But it disabled all usb devices(USB keyboard and mouse). How can I allow other devices except storage devices.

I am running Fedora 12 OS on my machine. I would like to disable the USB devices for normal users so that usb-storage devices cannot be plugged in. However at the same time a mouse or a keypad may/could have a usb connection. note that root should be able to use the usb storage devices. How can the same be done on fedora 12? I would prefer not to do it via the BIOS options.

I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.

I 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.

I'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

What 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.

I have a server running CentOS 5.5 with KVM capabilities. I need to migrate all the VMs to another server with the exact same hardware specs. The problem is it is running on individual harddisks, not shared storage. What is the best way to migrate to minimise downtime?

We 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.

I 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

I 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.

I have setup openldap and samba for authenticating Windows and Linux clients on my server. They are working fine. 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.

I have been searching for a software package that will install on CentOS5.4 x86_64 or RHEL5.4 x86_64 that I can allow users to access via the Internet for online web storage, pictures and they can manage their space (quota would be enforced). I am not having much luck finding any software?

I 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:
<?xml version="1.0"?>
<cluster alias="tmbackup" config_version="10" name="tmbackup">
<quorumd device="/dev/sdb1" interval="1" min_score="3" tko="10" votes="3">
[code]....

We 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.

My 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.

Is there a way to determine the IO size that is being used for reads and writes to an attached storage device? I am trying to pattern the IO sequences to storage. I have seen mentions to max_sectors_kb but the notes indicated that changing this value did not change the IO size to the storage.

I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

I am attempting to load CentOS 5 on an Acer 6900 desktop and I'm not even getting out of the starting gate. I am familiar with using linux but not the install procedure which is why I am beginning to dive into this. However, when I bring the system up off the Linux boot disk and go to install it's not even giving me the option of the controller so I can begin installing the os from the dvd-rom. This is what acer lists as the controller for the 6900: ich8 serial ata storage controller 2820 linux driver. I cannot find this driver for linux anywhere.
