CentOS 5 Hardware :: Moving System From Usb To E-sata?
Nov 11, 2009
I've a pc running Centos 5.4 with an uniq external hard disk hooked by USB (no internal drive). I'd like to hook it through e-sata to get performance improvment. So I am using a sata->e-sata connector to plug the disk.The disk is well detected by the bios, and Centos begin to boot but when it wants to mount the volume groups I've a kernel panic.VG and LV names are detected, but the system says it can't find them (there is a /dev/root not found error message)If I boot the system through a live cd I can mount and access VG/LV without problem any hint to get the system up and running through sata ?
grub.conf:
# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that

This might be a common topic but searching yielded me no results. I am trying to take one of my NAS servers from an IDE hard disk to a new SATA hard disk. Reinstalling the OS is not an option. I have a working system and have cloned the disk using Acronis True Image to a SATA hard disk.
First, Grub has to be reinstalled which is no problem. I have done this and it works just fine. My SATA drive is booting through Grub and attempting to load CentOS. Obviously the problem lies in that my original drive is /dev/hda and my new disk is /dev/sda
I have changed the following to try and correct the issue:
/boot/grub/menu.lst
/boot/grub/device.map
/etc/fstab
The new disk is still having problems booting. I have attempted before to create a new inittab but I am not sure it was successful and I encountered the same issues. After booting via Grub, here is the message that I receive
Unable to access resume device (LABEL=SWAP-hda3)
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
[Code]...
There must be some places that still reference hda. That first line of the panic message talks about SWAP-hda3. I have changed an entry like that in the Grub config but it still shows up at boot time.

I'm trying to move an existing FC10 install (created by someone else) from a 160GB WD1600AAJS SATA disk to a 160GB WD1600AAJB PATA disk (cursed trend of horizontally mounting SATA connectors at the end of the motherboard means the latest rev mobo doesn't fit in our enclosure!). I've used DD to copy the disk image from one to the other, but when attempting to boot, I get the following error:
Code:
Unable to access resume device (UUID=946f216f-0c24-4b02-a996-f42059970de7)
mount: error mounting /dev/root on /sysroot as ext3: no such file or directory
That particular UUID maps to sda2, which is the swap partition. Interestingly, both the SATA and PATA disk come up as /dev/sda on the motherboard. I kind of grok that the UUIDs are substitutes for directly naming the disks, and that they're referred to in fstab, initrd-2.6.27.12-170.2.5.fc10.i686.img, and in /dev/disk/by-* I'm guessing the problem is that the GUIDs (at least the one for swap) are no longer the same. How are they assigned to the partitions during boot?
I tried doing
Code:
swapoff -a
mkswap /dev/sda2
swapon -a
and put that new GUID in fstab and into initrd-* (using some steps I found elsewhere on how to gunzip/rezip it).At that point, I get a kernel panic on boot
Code:
Kernel panic - not syncing: CFS: Unable to mount root fs on unknown-block(0,0)
So I'm guessing that the other UUUDs have changed as well and I need to update them. How would I figure out what they are? I suppose I could change the references to /dev/sda*, but I didn't build this original image and I'm thinking whoever did had a good reason to go with UUIDs.

My problem is that I need to move a moderately complex system from an old system to a new system. The old system is a core 2 duo running on an asus p5k-se (p35 chipset) M/B, Nvidia 8500 gt, 3 x sata II hard disks, 1 x sata dvd, 1 x ide hd, 4GB ram. It runs opensuse 11.1 kde 4 as a desktop system + samba server, apache server, database server + other non-opensuse software. In addition some of the opensuse software is not the default 11.1 versions as later versions were required. The nvidia driver is from the nvidia repo. There are several file systems, some under LVM.
The new system will be a core5 760, asus p7p55d-e M/b (p55 chipset), nvidia 240, 3 x sata II HD, 1 x sata dvd, 4GB ram and possibly 1 x ide HD. This M/B also includes USB 3 & sata III. I have no USB 3 devices but this may eventually change. I have no plans for sata III and believe that it may be better to attach any sata III SSD to the sata II bus.
What I would like to do is to move the hard disks from old system to the new system. What I would like to know is, if the system is left at 11.1, is the system likely to work with the new hardware. If the answer is no, if the system was upgraded to 11.3, would the transfer of the hard disks then work? In order to upgrade from 11.1 to 11.3 using the DVD i believe I should get rid of all non-default repos. I assume that I should also get rid of anything that was installed from them, e.g. the nvidia driver and any software versions installed manually outside RPM. Also is there any default 11.1 software that should be removed either before or after the upgrade to 11.3

I keep getting this error in my log viewer every 2 seconds: Code: ata4: limiting SATA link speed to 1.5 Gbps I have a dual boot SSD and I have run many SMART tests in windows and linux, (using smartmon tools and the disk utility) and the reports are all 100% healthy..... My research shows that this error represents one of the following:
1. Problem with SATA controller
2. Changing BIOS to allow SATA
3. Changing SATA mode to PATA or AHCI
4. Replacing the SATA cable
5. Allowing the SSD to run at SATA II speeds, i.e. 3 Gbps
- Does anyone know how to try number 5, i.e. allowing the SSD to run at SATA II speeds? I am lost here and this problem has caused my machine to crash twice when watching a movie in linux/ ubuntu. (It is worth noting that the crashes have only occurred in linux and I have never had an issue in windows, so it does seem to be a linux setting somewhere, hence why I think it is a "allowing SATA II to run at correct speeds issue")

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 am wondering what is the fastest way for me to move files from a VPS running CentOS to my home PC? I do not have FTP or anything like that installed. Are there commands I can enter in putty, for example, that will simply download an entire directory on the VPS onto my home PC?

I have landed myself in a bit of a pickle. Needing to upgrade my system for 11.4 I went ahead and bought a refurbished Compaq. The intention was to merely replace the smaller drive with my existing drive. Only problem is that on opening the Compaq I found a SATA drive. Being a Compaq there is no space for a second drive, so I must copy my existing system via CDROM. As the 11.4 has gone through a number of updates since I installed, I cannot use the original installation CD. Downloading is out of the question for my link speed. I made an automatic backup when installing but am not sure where it is or whether it is also kept up to date. Anyway, does the backup contain merely the system and then require further transfer of home folders, etc? The alternative, of course, is to source locally the latest version that will not require hours of updating.

I help develop an Asterisk channel driver that uses USB audio devices to link amateur radio stations via the Internet.All worked well under Centos 5.2 but I recently upgraded to Centos 5.3. I now get either "cannot submit datapipe for urb 0, error -28: not enough bandwidth" followed by a kernel panic or choppy audio depending on the use of either single or multi-TT hubs. For at least 4 devices, things do work under Centos 5.3 if I have a PC with 4 USB ports and do not use a hub. Of course I need to use a hub in most cases errors but even with a single device connected, data seems to be lost resulting in choppy audio. We need the hubs to work for larger systems and PC's with only 2 USB ports.Hardware:
USB 2.0 Audio Device Class 1.0, C-Media CM108
USB 2.0 HUB, 7 port with one TT, NEC UPD720113 or
HUB 2.0 HUB, 7 port with multiple TT's, Genesys Logic GL852.

i have an fedora system, with no separate /boot partition. there is only one big / partition. I think this is the reason that preupgrade does not work. So I decided to build an own /boot partition. Could anyone give me a hint how I could do this easily? My idea is:
get a second hard disc and format this with 2 partitions (/boot and /)dd the partition1 to the new one.
is this a nice idea? my only problem is that my second hard disc is smaller then the current one. but the current one is not filled up total. but I can not dd to a smaller partition or? is it possible to boot with an live-cd an copy the partition with the cp command?

I have a 3 year old PC with 4 internal SATA ports. My old SATA hard drives, all smaller than 2TB, work fine. If I buy a 3TB SATA hard drive, will it work in Linux? Will Linux with GRUB be able boot from such a hard drive without a BIOS upgrade? With a BIOS upgrade? It's fine for me to upgrade my Linux to the newest kernel.

I have a Dell XPS 420 with a 500gb SATA drive on which Windows Vista is installed. I also have an additional hard drive that I wish to install for an Ubuntu installation. Is it possible to create a dual boot system with Windows on the original HD and Ubuntu on the newly installed HD?
Simply put, my computer will have 2 hard drives. The original hard drive has Windows installed. I would like for the second drive to contain the Ubuntu install so that the only thing changed on the original drive is the MBR (I suppose that's how it would work).

What I'm doing is attempting to create a minimalized CentOS which only installs the base components.
I decided that I'd install everything I need, then I did a ..
rpm -qa > installed-packages
I think used this new file to move all the RPMs that were used during the installation from ~/CentOS/disk/CentOS/ to ~/CentOS/graveyard
[root@localhost CentOS]# cat installed-rpms-no-vers | while read file; do mv disk/CentOS/${file}* ~/CentOS/graveyard/ ;done

I'm working on a new server and it has an Nvidia SATA array controller with 2 250Gb SATA drives configured in a hardware array. When the first screen comes up I'm entering the option Linux DD for it to prompt me for the drivers but nothing ever happens. The screen says that it's loading a SATA driver for about 15 minutes and then the screen clears and has a plus sign cursor on a black screen. What am I doing wrong? The only driver that came with the HP server are for Redhat 4 and 5 and SUSE, will any of those actually work?

I've been trying to install CentOS 5.5 on a newly purchased ASUS M4A88TD-M/USB3 motherboard. The board uses the sb850 AMD SATA controller which is not recognized by the CentOS installer.
I've done a bit of searching but can not find a Linux driver for the sb850 controller.
Has anyone been able to install CentOS on an AMD Sata controller?

I am still fighting with getting the right configuration in my grub file to chainload the second linux OS on my computer.
Computer:
2 hard drives (sata)
2 OS's (CentOS,Ubuntu)
CentOS is in and running fine. It owns the MBR and was in place before I added the Ubuntu OS. Ubuntu was added to the free space of the second hard drive in partition 5 and its grub was installed there. So I thought this would work for a grub stanza.
title Ubuntu (10.10)
root (hd1,4)

My system won't boot unless I have 2 sata drives. It doesn't matter what's on the second one. It even boots if the second "disk" is a powered sata to IDE adapter attached to an unpowered IDE drive.If I don't have the second drive I get this when I try to boot:
Alert! /dev/disk/by-uuid/ ...<your UUID>.... does not exist,I don't see anything that seems odd to me in my /etc/fstab file.
# /etc/fstab: static file system information.

Here is a dumb question (For some reason I can never remember Linux commands but can always remember DOS commands). I don't know what it is, but I think it's the "everything is a file or a directory" nature of Linux that I can't remember it.
Anyhow, I have an instance running on Amazon EC2. I have noticed recently that FreePBX (an Asterisk GUI) is warning me of shortage of disk space. So here is the output:
[root@ip-10-251-123-3 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.9G 8.8G 621M 94% /
/dev/sda2 147G 188M 140G 1% /mnt
[Code].....
So, it seems that I have a lot of space in sda2 but I don't know how to access it. how to do a symbolic link (or I can search with google) to move some folders to sda2 and then link them.

I have a logserver.log located at /usr/local/logserver. It's NSLOGDEPTH=100. I'm not sure if this is the reason but my log file is only up to 100 only..samplelogserver001.loglogserver002.log......logserver100.logThe other logs were already removed. I do not have any scripts on logrotate for this specific logs. My question now is: How can I move some logs automatically so that it will not be removed totally from the system. I'm planning to move it locally on the server and compressed it at the same time. My second plan is to move it on another server. Do I need to create a script on this or can be done on logrotate? (note: i do not want to remve old logs)

I have recently lost quite a bit of electronics around the house to a power surge/lightning strike (all items were on APC backups). The drives from my server were undamaged and I have a new server to host them in. I am having a hard time getting the new server to boot up with the old drives (trying to avoid a fresh install/rebuild of server). The hardware is very similar but not identical. At this point it gets to the following during the boot process:
Scanning and configuring dmraid support devices
md: Autodetecting RAID arrays
MD: autorun ...
MD: ... autorun DONE.
MD: Autodetecting RAID arrays.

I installed Ubuntu 10.04, and happened to have an Silicom Images PCXpress card plugged in, and it kindly added the sil_sata module.This is fine for this chip set.I think that my earlier installation of Ubuntu 9.04 used Libata, which does support NCQ and also has good legacy support for the Intel Intel ICH7 chipset I have inside my Sony Vaio SZ notebook. Also, libata also support Silicon Image chipsets as far as I can tell from URL...I wish to remove the Silicom Images SATA modules and replace this with libata and then test the performance between the two device drivers.

I have been trying for a few days to install CentOS 5.4 on an IBM x306 and I cannot get it to properly handle the Adaptec Embedded SATA HostRAID Controller. I have been working with Linux for a few years, but this is new territory for me. I typically use Debian-based distros, but I did some research on the IBM site and found out that RHEL is a supported OS for this machine. So, I decided to give Cent a try. I have some experience with Fedora, so it's not totally foreign to me.
Anyway, I'm a bit confused. Using the IBM RAID utility, I set up a mirrored pair of 1GB SATA HDDs. When I run the Cent installer, it sees the pair as a single array. I am able to partition the array and complete the install, but when I boot into the OS, it sees the drives as 2 separate devices, sda and sdb. I can pull either one of the drives and boot with a single disk, but it doesn't seem to behave as a mirrored pair. If I make changes on sda, they are not replicated to sdb. Also, I can't use the cli or GParted to format the existing space on the array. I get an error either way. I believe this is because Cent doesn't have a driver for the RAID controller, but I don't see why it would work in the installer, but not the installed OS.
My next approach was to start over and attempt to run "linux dd" at the start of the installation. I tried to find the driver for the controller on the IBM site so I could load it when prompted, but couldn't find a newer version than RHEL 4 Update 3 (I'm assuming this would coordinate with CentOS 4.3). I tried it anyway, but when I select the floppy during the setup, it tells me it's not for this version of CentOS. I read several times that there are .img files that might help me in the 'Images' directory of disk one, but I only see diskboot.img, minstg2.img, and stage2.img. I don't think any of these are what I'm looking for. I thought there was supposed to be a drvblock.img or driverdisk.img.
