I am having problems seeing SAS drives using Supermicro AOC-SAS2LP-H8IR adapter. The operation system is CentOS 5.6 64bit version. The operation system is installed on a SATA drive and the motherboard is an Intel Board "Classic Series" "Rockfish" G43 - Socket LGA775. From the OS I cannot see the drives. BIOS does see the PCI card and it ends there.

The installer can't see my raid controller (I assume) as I'm getting the following error:"Error opening /dev/mapper/isw_jbhgjgjj_Vol0: No such device or address"It just sees them as 4 individual drives: sda, sdb, sdc and sdd.Please note that I have set up the RAID 5 in the controller bios interface and the image name is Vol0, which it seems that it tries to load but for some particular reason it can't.I have also tried different bios settings and nothing worked.

I preloaded the required RAID drivers for the CentOS and started the installation. Everything went fine until the part where the CentOS formats the HDD - it took 12 hours and the process still goes on. I cannot determine whether the install process is stuck or the HDD is still being formatted.how long the formatting should take considering the above mentioned configuration?

I will install CentOS as Fileserver and XEN as Dom0 on a 4GB SD Card. The SD Cart is in a SD to IDE adapter(?). All other files (for example the Xen hosts) come on my 6TB Raid. I need only the basic system, samba an xen on the SD Card. How can i do this? Whats is the best partition table? How can i mount the Raid first on start up(for access the needet files to start Centos and services)?
View 1 Replies View RelatedIm a very basic Linux/ Centos user. I have Putty installed and a USB to serial adapter. All settings seem to be right as far as speed, etc, but I'm not sure how to list the device to open for the program. The default location it gives is "/dev/ttyS0" Trying to find where the USB is located using the "/sbin/lsusb" command gives me-
Bus 001 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000

So I think this means that it is on bus 4 correct? So how do I list this for putty to open the device.

View 5 Replies View RelatedI am running 2.2.4 and CentOS 5.3 (RHEL 5.3 clone). I have two Ethernet cards: eth0 and eth1. Eth1 is connected to the Internet; eth0 is connected to all my virtual machines; iptables connects eth1 to eth0.
A new machine I am adding needs to be off eth0 and eth1 (security reasons). Question: is there a way to make up a third fake Ethernet card that I do not physically have (eth2) and assign it to my new VM? How do I do this? Can I get away with some thing like this?

I felt the urge to build my own "Incredible PBX" system, and in the process downloaded pbxinaflash-i386-5.4.iso which is based on CentOS 5.4. The PC that I'm using is an old desktop, and the onboard ethernet adapter is not working, so I installed Trendnet PCI Adapter (te100-pciwn h/w : 2.2 R), which used to work greatly under Windows XP. Since my on-board ethernet adapater doesn't work, I disabled "eth0" device, and I modified eth1 device to load during boot. But, for whatever reasons, eth1 fails to get the IP address. I thought the driver that is part of CentOS 5.4 may not be working, so I thought of building the driver from the files provided in the CD (that came with TrendNet adapter box).. and unfortunately my attempts to build the driver have also failed.
Following files are attached in the zip file
- basedata.R3721 (info collected by ./getinfo.sh all )
- Directory 2.2.X has "te100.c, makefile, kern_compat.h copying.txt" (These files came with the Trendnet CD)
- errors (makefile errors when tried to build te100 driver)
From what I understand, TrendNet TE100-PCIWN is based on "Realtek Semiconductor Co., Ltd. RTL-8139" chipset. How to get my ethernet adapater (eth1) connected to internet.
I have USB-Bluetooth adapter and Centos 5.5, i plugged in adapter to USB, reboot. then i get this with /sbin/lsusb code...
also, when im searching for devices with phone, i can find my computer (my Bluetooth adapter), but when i press to connect from phone, it says Connection Failed...
thats kind of weird, because overall process seems to be set up ok, and i can find my PC without problems... any ideas why would connection fail then?

I have spent them with Fedora and liked it a lot. Today I decided to install CentOS as this looks like something I would like to be using in the future. However a problem I could not solve came right at me after the first boot.
I have one eth0 device which is onboard lan and that was correctly recognised and activated. The second device is F5D5055 Belking USB Gigabit ethernet adapter. There was no problem with it whatsoever under Fedora. According to all the info it should be automatically recognised on kernel 2.6.14 and later. However when I plug it into the USB port, I can see its correct name in the device manager but it is not recognised as a network device. I have configured my Fedora as a firewall/router for my lan and definitely want to use that interface.
Hopefully without needing to do anything in the realm of compiling kernel, cause that is where my half a day long attempt to fix the problem left me.
Has anyone successfully used an Adaptec 2100S in a RAID configuration? Specifically, RAID1?
Drivers exist for earlier version of Red Hat, but building an using a driver disk results in the error:
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.
We have two recently installed centos machines, each running 5.5, and hosting an elastix pabx distro as well as a Virtual PC instance. On both machines, the network adaptor fails completely every week or so. As they are remote machines, the only option we have when this happens is a manual reboot.
I might be barking up the wrong tree here, but the only significant difference on these machines to others we have deployed is the Virtual PC instance. The machines have dual ethernet ports, with one assigned to the virtual PC. When the network failure occurs, it does not effect the virtual machine, which continues along merrily.
My expert colleague does not think so, but can anyone think of any way that our configuration could be causing the problem? If not, does anyone have any ideas on what the problem could be, or where I would start looking for information on the machine to debug the issue?

I have two HDs, one is a 80gb OS drive(Parallel ATA) and the other is a 1T storage drive (SATA). Well after each reboot they swap between /dev/sda and /dev/sdb, over and over again. One boot the OS is /dev/sda and the next its /dev/sdb, same goes for the second drive. This makes it difficult to setup fstab so it will mount the large storage drive on boot.

View 1 Replies View RelatedHDD vs SSD durability
After reading Jeff Atwood's recent blog post on solid state drives, I'm somewhat deterred in wanting to own one. I basically want to use solid state drives in my home network for the following purposes (all machines running 64bit Linux):
My main (pwn3r) desktop computer. This will be my main workstation for work, video encoding, etc. This will be running an Intel 980x 6-core processor, making it a beast. My hard disk configuration will be:
RAID-0: 2 Crucial 128GB Solid State drives for the main operating system(s), essentially providing 256GB of incredibly fast storage.
RAID-1: 2 WD 2TB Hard Disk drives for media and backup storage.
My network firewall computer. This will be running Untangle on my home network for content filtering and firewalling (if that's a word). It will be running an Intel Atom D525 dual core 1.8GHz processor. The hard disk configuration will consist of a single small 16-32GB solid state drive for the operating system and little, if anything, else.
My home HTTP/SFTP/file/backup server. This will be running a dual-core Intel i3 processor; it will be used for some video encoding, as a local DLNA server, a HTTP server for a few largely static files and perhaps some interactive scripts, a SSH server, possibly OpenVPN, and will be used to back up critical files over the network. It will be running RAID-X (where X > 0), meaning RAID-1 or RAID-5 or 6 for fast, redundant data storage, as well as a small SSD for the operating system.
I'm not exactly made of money, and I can't really count on buying four new SSDs every year or so. I can understand replacing them in computer number 1 once a year... maybe, but for the other computers which won't be utilizing the drive very much (ie: they're not power machines), it seems ridiculous to buy new drives this often.
My question is this: can I actually depend on solid state drives like I would on hard disk drives? Also, is this the best economic option? I'd like to save as much power and heat as I can, and solid state drives seem to be the best option at this point.
