CentOS 5 Hardware :: Direct Attached SCSI Storage Not Showing Up In O/S

Oct 14, 2009

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.

Ubuntu :: Boot Freezes At SCSI Attached Devices?

Jul 22, 2011

i was fooling around with ATI graphics settings and after i went to reboot my Desktop it kept comming up with odd symbols instead of a log in screen, then i started to try and do things with a LiveCD and screwed things up even more so now any time i attempt to boot, even into recovery, it stops at the line

Ubuntu :: Can't Uncompress A File In A Network Attached Storage?

Jul 5, 2011

I have a fairly simple setup for my Network attached storage. I have a 1TB external hard drive connected to my Asus RT-N16 router through USB. I have enabled file sharing in the router, and thus the hard drive shows up on the network as a shared folder. No hassles, I can read and write to it.

Because I want to use this hard drive for networked backups, I tried to get it to mount on boot with fstab. Here is the line in my fstab file :

Code:
//192.168.1.1/SharedFolder /media/SharedFolder smbfs guest,_netdev 0 0

It mounts fine, no problems, and once again I'm able to read and write files to it. The problem occurs when I try to access the mounted drive and uncompress an archive file for the duplicity backup program. It gives me a list of messages showing that all the files inside the archive failed to uncompress because of error messages like these :

[Code]...

If I try to extract the same archive by manually going to Network > RT-N16 (Router) > Shared Folder, it extracts fine. But I need this folder to be mounted on boot because I use it very frequently. I tried changing smbfs to cifs and it still didn't work. Please not that my knowledge of samba, network storage and file systems is very basic. I tried searching the internet for more information about this but wasn't able to find much information that pertains to this particular problem. Hoping the linux pros here could give me some pointers ..

Networking :: Add Network Attached Storage As Download Path

Feb 28, 2010

I have got a Arch Linux laptop running KDE. I have recently purchased a Dlink DNS 323 network attached storage and have installed Debian Lenny on it. I have been connecting to it via ssh and have created a network folder on Dolphin for easy GUI access ( using ssh protocol). However I cannot seem to figure out how to download stuff directly to the network drives. In firefox, it does not allow me to browse to the Dlink when I try to specify the download path.

Red Hat :: Mapping /proc/scsi/scsi Entries With Respective Device Names In /dev/ Directory

Apr 11, 2011

In my understanding, the way /proc/scsi/scsi gets populated, /proc/paritions also gets populated in the same fashion. i.e. the description for first entry of /proc/scsi/scsi can be seen in the first entry of /proc/partitions and same for rest.

So, With this assumption, in my project, I used to relate first entry of /proc/scsi/scsi with first entry of /proc/partitions to get its total size and same for all entries.

But, I observed some differences in following scenario, where

1) The first 4 entries in /proc/scsi/scsi are SAN luns attached to my system and for which the actual device names in /dev/ are sda,sdb,sdc and sdd.

2) The last 4 entries are the internal HDDs on same system. In /dev/, their respective device names are sde,sdf,sdg & sdh.

(Output attached at end of the thread)

But in /proc/partitions, the device order is different.

You can see their respective sizes in /proc/partition output as well.

So, my question is, in this particular scenario, I can't relate the first entry of /proc/scsi/scsi with first entry of /proc/partition. i.e. scsi0:00:00:00 is not /dev/sde, because it is actually /dev/sda.

It seems that my assumption is wrong in this scenario.

Is there any way or mechanism to figure out actual device name for an entry in /proc/scsi/scsi in /dev/ directory?

How can my application should relate /proc/scsi/scsi entries with their respective device names and sizes?

Some of our workstations have LTO's attached and they seem to drop off every now and again, the only thing which picks them up again (besides a reboot) is the famous rescan-scsi-bus script from here

The thing is that I'd like non-root users to be able to run this script, which in turn needs root to /proc/scsi/scsi

CentOS 5 Hardware :: Scsi Drive Not Recognized?

Feb 21, 2009

I just installed centos 5 on a hp dl380 server and it has 2 72.8 scsi gig hard drives. The problem I am having is that only one hard drive is being recognized and it is not being recognized as a scsi. This is what I get from fdisk -l

Disk /dev/cciss/c0d0: 72.8 GB, 72833679360 bytes
255 heads, 63 sectors/track, 8854 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p2 14 8854 71015332+ 8e Linux LVM

as you can see, the system doesn't even see the second hard drive. How do I get both hard drives to be seen and how do I get them to be recognized as scsi?

CentOS 5 Hardware :: Panasonic LF-D201 SCSI DVD-RAM Onto 5.3

Aug 6, 2009

I've managed to install Centos 5.3 (with Gnome) from a temporary IDE-based CD drive. This has now been removed and, instead, I have added a SCSI-based Panasonic LF-D201 DVD-RAM drive onto channel-B of the Intel SRCU32 (LSI clone) SCSI RAID card.

it seems that Centos cannot see the DVD-RAM drive at all - not even as a simple CD drive.

CentOS 5 :: Unattended Kickstart Install Supporting Both IDE (hda) / SCSI (sda)?

Apr 6, 2010

Can an unattended Kickstart support both IDE (hda) and SCSI (sda)? The goal is to to create a new virtual machine from scratch. What I have works for Parallels in which a new VM defaults to emulate an IDE hard disk. It does not work for VMware Workstation which defaults to emulate a SCSI disk.

The relevant Kickstart section: bootloader --location=mbr --driveorder=hda --append="rhgb quiet"

clearpart --all --initlabel --linux --drives=hda
part /boot --fstype ext3 --size=100 --ondisk=hda
part pv.2 --size=0 --grow --ondisk=hda
volgroup VolGroup00 --pesize=32768 pv.2
logvol / --fstype ext3 --name=LogVol00 --vgname=VolGroup00 --size=1024 --grow
logvol swap --fstype swap --name=LogVol01 --vgname=VolGroup00 --size=1024 --grow --maxsize=2048

Can the Kickstart file be made to not care what drive type is there, or conditionally handle either type?

Anyone know what version of spam assassin is newer 3.3.1-3 or 3.3.1-52 I would assume 52 is newer but I don't know if once it reaches 99 it going to 2 Example 3.3.1-99 ---- 3.3.1-2 -----3.3.1-21 and so on. I could be completely off but can anyone just clarify if 3.3.1-3 is newer or older than 3.3.1.52

CentOS 5 Hardware :: SCSI Host Interface Card Not Recognised?

Mar 16, 2009

I've just put together a Centos 5.2 system using an old Future Domain SCSI card which would allow me to hook up an external DAT drive. On its BIOS screen it advertises itself as an AHA-2920 which should be handled by the aic7xxx module. However, the module doesn't even get loaded unless I force it in /etc/rc.modules and even then it doesn't pick up the card.

Driver disk is invalid for this release of CentOS

CentOS does not recognize the adapter out-of-the-box as a HW RAID controller, but does recognize the individual disks.

I attempted to use software RAID, but the installer craps-out after a while and the screen locks up.

CentOS 5 Server :: Configuring Piranha To Load Balance (Direct Route) 2 Ports

Feb 18, 2009

I seem to be having a strange problem configuring Piranha to load balance (Direct route) 2 ports across 2 w2k3 servers in a test environment. What is strange is that 1 of the ports are working fine but the other port doesn't work. I've read many how-to and after many frustrating hours I disabled the firewall, iptables and arptables services and one of the ports are load balanced across the 2 real servers. Here's the environment.

[Code]....

I can telnet from the client to the realserves on both ports and it's works. When I telnet to the VIP only one port gets through and the other gives me "could not open connection to host port 32777 : connect failed. The configuration in Piranha for one port is the same as the other. I can't help but think that some other configuration for port 32777 was missed.

CentOS 5 :: Build A Bootable System Image On An Attached Hard Disk On A Running Machine?

Feb 27, 2011

I would like to build a bootable system image on an attached hard disk on a running CentOS machine.The hard disk would be moved to a headless server, where only SSH access would be available. It seems that all the documented install methods assume that the installation runs on the taget machine. In this case, I would like to create a bootable system image of CentOS on a running host system. The new install mage would generally have a newer version of CentOS than the running host system where the image is created. Also, I would prefer
to do a text-based install.

The reason for all this is that I have network access to several remote machines. I can ask disks to be moved between machines, but I have no physical access. In order to do software testing, I would like to have several system disks with different installed CentOS versions. It would be easer if I could build the system disks on one single machine. The hardware an all machines is very nearly identical.

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
