CentOS 5 :: Disabled FakeRaid Still Getting Recognized
Feb 9, 2009
I can't get CentOS to stop seeing my drives as a fakeraid, even though I disabled the raid settings in the bios. Therefore, I can't install. Previously, this box was running Vista 64 bit. I have an nVidia mainboard and two 500 GB sata drives. The mainboard offered raid support, so I enabled it. Windows saw the drives as a single raid0 drive and installed on it flawlessly. Never had a problem. Two days ago, I finally got off my horse and decided to get rid of windows and install CentOS. I left the raid intact, installed CentOS on the fake raid. Upon rebooting, GRUB wouldn't load. Booted up a live disk, fdisk saw the drives separately but couldn't read data from them.
Tried a second install, same problem. Wiped out the the data on the drives using gparted. Tried a third install, same problem. Did some research, found out that my raid was really a fakeraid and that a better option for my needs is a softraid. Disabled the fakeraid in the bios. Booted up the installer. It still loads the nvidia /dev/mapper driver. It still sees the drives as a fakeraid. Wiped out the drives using gparted. Booted up the installer. Still sees the drives as a single /dev/mapper/nvidia_lkjwer drive. Installed Ubuntu to see if I'm crazy, or if it's centOS. Ubuntu installed w/o a problem (on a single drive). Enabled, disabled, tweaked every freaking possible bios setting. Still sees the drives as a fakeraid.
we are using firefox-3.0.15 from the CentOS-Repository and the adobereader plugin from the adobe-repository. We have a curious problem with adobereader-plugin in firefox.When a pdf document is displayed via the plugin, i.e. within a tab in firefox, all input fields are disabled. I cannot enter a search string or fill in fields. The cursor and page up/down keys are also disabled. But when I configure firefox to open pdf documents with the external acroreader, everything works fine.
Additional notes:* We are just migrating from SuSE. Some user profiles are working as expected without problems. Unfortunately, I was not able to figure out the important files: I traced all of firefox' file operations on the user profiles, but there are no significant differences between working and non-working profiles (I just compared filenames, not content).* the same adobe-plugin works with firefox 3.0.15 from mozilla.org* I also set up a clean i386-Centos 5.4 from original CD, SELinux disabled, updated and created standard user. I only added the adobe-repository. The same effect, no search avaible.
My symantec 10.1 autoprotect on top of a Linux ES 3.0 server shows disable on the task bar and I am unable to restart it with the services any suggestions for a newbee
would ask how to fix this warning that comes when i start my centos 5 virtual machine that run under windows 2003 std, previously it run smoothly with linux centos 5.

I have recently installed CentOS on my server and I am trying to install a Teamspeak server as well as a web server using ISPConfig. But, for installing a Teamspeak server I wanted to create the user account "teamspeak" to run it so my files under root are not accessible for security reasons. I was wondering if there was a way of creating the user teamspeak with a disabled login, I know in Ubuntu to do this you do: adduser --disabled-login teamspeak
I have 6 GiB RAM installed in a server. The bios shows 6. They're all identical sticks. The OS says there's 4 though. I'm not sure what to do now. Dell says it should be able to use up to 12 GiB.

Screensaver mode was engaged in KDE via Control-Alt-L. Then after a while the screen when blank. I was able to get the login screen by moving my mouse; however, the keyboard was somehow disabled. It would not transmit any input. I hit cancel with the mouse and the keyboard could not bring up the login dialog box. This doesn't happen if the screensaver is engaged briefly - only for an extended period of time (perhaps 30 minutes)
I have just installed a NEC 3.0 PCIe board in my CentOs 5 box, but the card is not recognised, and no drivers seem to be loaded for it. lspci says: USB Controller: NEC Corporation Unknown device 0194 (rev 03) The vendor says the board is supported on Linux kernels 2.6.16 and later. uname says my kernel is 2.6.18-194.17.1.el5
How do I get this device to be recognised, and drivers loaded for it?
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 Device Boot Start End Blocks Id System /dev/cciss/c0d0p1 * 1 13 104391 83 Linux /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?
I have an old IBM Xseries 300 server that i can use. So, i am trying to install Centos 5.3, but during the installation , no disk can be found. I have 2 disks (1+1 in mirror) connected to an IBM serveraid PCI card.
I installed Debian Lenny, and it recognize the card (so the disks) immediatly.
Have installed Centos5 in SUN VirtualBox with Windows XP as host as a safeway to familiarize with Linux.The system works well,except I cannot get my printer to be recognized (Canon MP170),which is working on Windows.Is there any Command line instructions which will fix this,or any other solutions?
I set up my vsftpd server, but when using "sftp servername" it's not using vsftpd but another (what seems like) built-in sftp server. Even when I stop the vsftpd service I am still able to get a prompt to log in. I haven't installed any other ftp servers.
With CentOS-5.5, centos plus enabled, my LaCie external hard drives are not recognized even though connected and powered up before booting. I am logging in as root. Previous 2.4 kernel RHEL Enterprise 3 required a special scanning script which worked with this computer. This current system will not recognize the drives as hardware. On the other hand the drives with USB 2.0 ports automount connected with USB and also are recognized in the hardware list. what diagnostics to do to find out what layers / drivers are missing.
I am trying to install a 3com 3c905B NIC. When the system boots, it is recognized but Centos5.6 does not see it.I have tried to manual load the 3c59x module but no luck.My kernel is: 2.6.18-238.12.1.el5 #1 SMP Tue May 31 13:22:04 EDT 2011 x86_64 x86_64 x86_64 GNU/LinuxI have also tried to install a TrendNet TEG-PCITXR and a SpeedStream SS1019. Again, the BIOS recognizes them but not the OS.If I can't get CentOS to recognize atleast one of these, I will have to switch to another Distro.
I have 2x320gb drives that i want to use as a system disk. Should i use intels ICH10r on motherboard or can i do a software raid on install...I don't want to buy a hardware raid controller.
on my server (fax server)with Cento O.S 5.2 final kernel 2.6.18-92.el5 the external serial modem 56k us robotic is not recognized.Kudzu not notes the modem.PS .On the same server ,same modem ,same serial but with Centos 4.5 ,this as regular detect.
I have a problem to configure my wifi card, a dwa-110 from D-Link, it is not recognized when I launch System / network device control (only ethernet connections appear), and it is the same thing in Administration / network / network configuration. But if I launch administration / hardware / system devices, the last line is "Ralink 802.11 bg WLAN"... When I try to add in the window "network configuration" (from above) some new stuff, I specifying the kind of hardware (wireless) and when I have to enter the name of the card I don't see my card. On other OSes, I used ndiswrapper, but I wasn't able to install it on CentOS (dependencies required and it's hard with only a USB key to install the stuff...) How to see if the card is recognized, if I have to use ndiswrapper and so on. I have an internal PCI network card also, maybe it is this card which is recognized.

I have a single disk running the base OS and just installed 2 x Seagate 500GB SATA 3.0 drives in a RAID1 set that I would like to use for data storage. The OS sees the drives individually but not the RAID. Has anyone worked with a similar board and has any ideas what I need to do to get the OS to recognize the RAID1 array?
I have installed Ubuntu 9.10 (64 bit) as a dual-boot setup (along with Win 7) on my desktop. I can't emphasize how much faster Ubuntu loads when compared with Windows. There is only one problem though, I cannot figure out how to use my existing FakeRaid array (two 2TB hdds setup as RAID 1 - mirroring) to work with Ubuntu. I am NOT trying to install Ubuntu onto a raid array (I have Win 7 mounted on a separate boot drive , 4 hdds altogether, two for each OS and two for the RAID array). The raid array works fine in Windows and it's an Intel Raid Controller. How can I do the same for Ubuntu without losing any data? Is this possible?
I have just installed Ubuntu 10.10 server on and old pc to use it as a backup server for my and my kids pc's.The pc I use for the Ubuntu server has two sata disks on a fasttrak 378 controller, fakeraid as I have learned, and a single pata disk. I have installed ubuntu on the single pata disk and was planing to use the fakeraid as the samba share.
I just got 5.2 installed on my HP zd7000 laptop. I have a Zonet ZEW2502 USB Adapter but doesnt seem to be recognized. I tried to search in the forums and Google but didnt find any tutorial. point me in the right direction? or do I have to buy a different USB adapter?
i've got a DELL Tower UPS 1000W which i would make work with a Linux CentOS 5.4 64-bit (kernel 2.6.18-164.11.1.el5) system using USB connection.Dell claims that this UPS is 100% working with RHEL 5.x (w/ serial and usb), but they don't provide support for CentOS (even if it's quite the same linux distribution)...When i plug in the USB cable the system reports:
usb 6-2: new low speed USB device using uhci_hcd and address 3 usb 6-2: configuration #1 chosen from 1 choice
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.
I got gigabyte chipset with an raid support. Currently I have 2 hdd's running in raid 1. When I was first installing ubuntu 11.04 server my fakeraid was detected, and I assigned a name for it in the initial installer and it was auto-mounted (working 100%) ever since.
However I was forced to reinstall my ubuntu server, and this part was somehow skipped in the installer.
HDD can still be seen in /dev/mapper I can see control jmicron_GRAID -> ../dm-0 jmicron_GRAID1 -> ../dm-1
I have an MSI 845E Max Motherboard. I just purchased the computer USED. I have no manual and from all accounts of the online manual, this MB is doing the impossible.Connected to this MB are 2 WD 60GB hard drives. Bother are recognized in the bios. When booting from the live CD, and running the disk utility I can plainly see that there are the 2 drives and one striped array (using both of those drives).There is no settings in BIOS for any array. If I remove 1 of the drives, the disk utility sees only 1 drive but still sees an array. I can find no way to eliminate, recreate, oe manipulate this array in any way.To make matters worse, I attempted to install an older FREEBSD, using it it saw both drives (no raid). Using their Disk utility I re-partitioned both drives and continued the install. Unfortunately the version I had was an older one and it could not complete the FTP install (And I would rather have Ubuntu anyways). Though through this action I believe that I have destroyed the integetery of the raid and if it is to be used it needs to be fixed.So.. how do I fix something that my BIOS is not supposed to be capable of doing? Has anyone else experienced this issue.
My motherboard has a BIOS feature to support RAID1 for two disks. I know it's FakeRAID but that's what Windows can work with. I've read that Linux's built in softraid mdadm is better so I'd prefer to use that for Linux's own filesystems. Can I enable FakeRAID in the BIOS without it affecting Linux in any way? Is it possible for Ubuntu to read and/or write to the NTFS partition that's raided with the fakeraid?
Also, if running mdadm in RAID 1 how much risk is there of losing data if the computer crashes? Is e2fsck able to repair a filesystem on a RAID 1 setup?
