I want to create RAID disk on machine_2. Next, I want to replace one of the RAID disk from machine_2 to with the RAID disk from macnine_1. Then I want to build the RAID disk from machine_1 with machine_2 data. This is my question:
How to determine the physical drive the system boots on in a RAID array?
Or
How to determine the RAID disk from machine_1 in machine_2?
When running cat /proc/cpuinfo under Linux, a variety information is kicked-back. For example:
> cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Xeon(R) CPU 5130 @ 2.00GHz
[Code]...
First, what does all of that actually mean? I see I have a processor 0 and processor 1. Does that mean Linux is reporting both cores of the CPU, or, since it is a VM, the two that I happen to have right now (even if they're on physically different CPUs)?
Second, how can I get a similar information dump form the command line in Windows? Third, is there a way using either platform to determine the number of physical CPUs versus total CPU cores?
Some site will have the location listed, or some mirrors are hosted educational institutions so you can easily identify the location of those mirrors. However How can I determine the location of an unknown mirror? Like for example, say I want to download a DVD install iso of CentOS. I look a the download mirrors and I see list of [URL]. Now from looking at that list how can I tell which one is closest to my location?

Hello all,
I have opensuse 10.3
Everything has been working fine for several months, then out of the blue, something changed.
I woke up to see that the system was down.
When trying to start it, it goes to
can't determine runlevel and stalls - OR - if it gets past that point, it stops at setting up the hardware clock
What steps can one take to solve the problem?
TIA
I am in need of finding out the physical interface corresponds to eth0,eth1,eth2., As similar like the lscfg command which is available in the AIX operating system. The output given below got it from AIX OS.
$ lscfg -l ent*

ent1 U787B.001.DNWFFC6-P1-C4-T2 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
Is there any utility/commands available to find out the physical interface ?
I have a 4 disk software RAID array made up of Seagate drives. Let's name them sda, sdb, sdc, sdd. And let's say SDC is failing. Big question. How do i find out which of the 4 physical drives it is? They all look the same to me when i open up the PC case. Maybe some utility which will load up heavy usage on just one drive and i will try to put my finger on them and figure out which one is vibrating? Or maybe there is a smarter way?
View 1 Replies View RelatedI am trying to figure out the "actual" disk size used by my system. When I run the "df -h" command,I am not taking here into consideration the shared memory of 2Gb as it is a sort of virtual shared memory and is not allocated physically. Is that correct ?

Could I get 50GB from /dev/sdb1 and add it to /dev/sda1 ???
### TO DO: Determine the report file name based on the source directory name and current date### The report name and thumbnail directory must follow this pattern: source-%j-%H### for example, for pictures in /home/you/pictures, the file name will be: pictures-%j-%H### HINT: Use sed to extract the directory name from the path and combine it with date command output
View 1 Replies View RelatedIve been running VirtualBox with a windows XP installation for some time, on an opensuse 11.0 host for some time. Recently, however ive been having issues with suse, and want to take my virtual XP and make it a primary bootable physical partition, on a second disk
I know it can be done, but im not finding how exactly.
What ive tried so far. I've taken VBoxManage terminal tool and converted the VDI to a .img file, and tried to move that to my second physical disk, but it didnt work at all.
After some thinking, I booted to acronis true image within my virtual machine, and cloned the C:/ drive of windows over to my second hard drive. That got me further, but doesn't boot fully. Comes up to windows xp logo, and black screen boot loops.
Ive heard about using vditool to create a .raw file, and then go from there, but im at a loss to find vdi tool
How can i move my virtual machine to a physical, bootable partition on a second drive?
I am currently using windows xp, but I have acquired another hard drive and wish to install ubuntu to it, unfortunately i do not have a working cd drive. I have loaded the newest iso in daemon tools and it asks me if i want to install it in windows, or restart my computer to do a full install. i wish to do neither. i want to install a full copy to my other drive with the virtual cd drive. I have found alot of help dealing with installing it on the same drive as windows or something that would require a floppy drive. this task seems like it would be alot simpler than installing on the same drive, buy maybe not. Did i miss a tutorial somewhere?
View 2 Replies View RelatedMy raid array has failed. I have two disks /dev/sda and /dev/sdb./dev/sdb has failed and I could not rebuild the array(madm returned that the device is busy) so I rebooted the machine. After that, the whole sdb disk went missing, as it now only shows sda in fdisk -l.Did the disk went totally dead or my raid glitched?
View 8 Replies View RelatedConsider the following scenario: you have two disks that are kept synchronized by some method. Could be RAID, could be LVM snapshots, could be a script. However, something has gone wrong. The disks are out-of-sync and you don't know which disk received which updates. You want to manually re-sync the disks but how do you figure-out which file to copy where?
I'm thinking of saving recursive directory-listings of the entire disks to text-files. Sorting them on last-update and removing all identical entries from the files.
I have a feeling that this is something that can be done with just a few command's but I need some help to get me started.
how easy it would be to read the contents of a physical disk that was part of a larger logical volume. The disk contains a "Linux LVM" partition that spans its entire size. My problem is that one of my disks died, and I have to send it back for a warranty replacement. However, the disk is dead, and I can't zero it out. I'm just trying to assess how difficult it would be (or at least how likely it would be) for a tech that's checking out the disk to get at the data.
View 4 Replies View RelatedI am using LVM2 and have shrinked my /home partition and extended my / partition but I'm not sure if I used all the free space when growing my / partition. How can I find out? I prefer using the terminal if there is a graphical way to do this but I would like to know both ways if there are two ways.

I recently built a "new to me" computer and can't get it up and running. HDD's, DVDROM, Mem is all detected ok. But just won't boot linux for some reason.
Heres the setup
ASUS P4C800 w/P4 2.4Ghz
2GB RAM
Excelstor 160GB (IDE)
WB 80GB (IDE)
SONY DVDRW (SATA)
BFG (nvidia) R84512GSP video
Tried different combination's of which drive is mstr/slv boot order with and without the new memory(1bg of it) nothing seems to work. I'm trying to install Ubuntu 9.10 I can get to the main screen where you have the option of live/install. Once you need to get past that I get a blinking cursor on the top left of my screen...and thats it. I've tried letting it sit and makes no difference. This happens with every distro I've tried to boot, Ubuntu, Fedora, CentOS, they all crap out at the exact same spot, got be hardware right.
I'm familiar with editing Grub's "menu.lst" file to add additional OS's to the boot list. Does Slackwares Lilo have a similar config file ? I need to add a second physical drive with Windows 7 on it to the boot options in Lilo. If it's not a config file, how do I add a second os to it ? Slack and Windows are both already installed on two different physical drives so I won't be installing, I just need to add the Windows drive to Lilo.
View 5 Replies View RelatedI'm on stretch and have faced system crashes multiple times during the boot, when my system was hibernating.
How may I get to the cause of this issue and how could I correctly report it?
I'm currently running Ubuntu (w/ GRUB) and Windows XP. I'd like to remove Ubuntu and run the recovery on Windows XP because it has started not running correctly. The computer is about 5 years old and I figured I'd just wipe it clean and start over (read: remove Ubuntu and reinstall windows via the recovery console).
I intend to follow the tutorial here: [URL]
However, I'm confused about determining the boot device number for Windows. I've run "sudo fdisk -l" and I can identify the windows drive in the list it says:
Device: /dev/sda1
Boot: *
Start: 1
End: 19352
Blocks: 155444908+
Id: 7
System: HPFS/NTFS
Am I looking for the 7, the 1, or something completely different? This is also the first partition on the list.
sda2 (id: c) is a FAT32 drive. I think this is the recovery partition included on the HP desktop.
sda3 (id:83) is Linux
sda4 (id: 82) is swap
I just need to run fixmbr.
I wrote a GRUB multi-boot configuration so I can boot multiple distributions and have storage space on one 32GB flash drive.
set imgdevpath="/dev/disk/by-label/multiboot"
Code: Select allmenuentry 'Debian Jessie amd64' {
set isofile='/iso/debian-8.0.0-amd64-DVD-1.iso'
loopback loop $isofile
linux (loop)/install.amd/vmlinuz
initrd (loop)/install.amd/initrd.gz
}
This works in virt-manager when I boot the physical usb device a virtual disk with a usb bus and it works flawlessly, but when I plug it into a physical machine the cdrom detects fails to mount /dev/sdb1 as fstype=iso9660.
I was wondering how can I determine among the modules loaded at boot which of them are really necessary and which are not, in order to reduce the boot process time and have a more "elegant" system start.
I know this theme is a little bit of complicated because it depends of the user's point of view and demand a high knowledge of which things are happening in your system but I need somewhere to start improving the performance of my debian system.

Ok, so I have installed openSUSE 11.3 on my Lenovo Thinkpad T61p, setup the wireless adapter (why is this so difficult?) and installed a few applications. I do like the look of openSUSE but would like to check out a few other flavours. With my Windows 7 (can I say that here?) machines I can create a system image and a system restore CD with a fair amount of ease. Is there a similar process available for Linux?
View 5 Replies View RelatedI installed OpenSUSE 11.2 on a computer. I would like to clone the hard drive so that I can put the same disk image on another computer with the same hardware.
I used clonezilla to create the hadr disk image, when I restore the image on another computer, I got errors and failed to boot. I later learned that, I have disk-by-id on /etc/fstab and grub/menu.list. So, I went into the computer that I tried to restored using Knoppix liveCD and manually changed the fstab and menu.list so that it used something like /dev/sda1, /dev/sdd2, and /dev/sda3, instead of /dev/disk/by-id/WD....-part1 (part2/part3). When I re-booted the new computer, it still failed to boot.
So, do I have to go back to the original computer, manually edit fstab and menu.list to /dev/sda1 /dev/sda2 /dev/sda3, then re-create the disk image? Is there anything I have to change so that it does not use disk-by-id any more?
I have OpenSuSE 11.0 running on a machine. I want to be able to automount a USB disk but it seems at the moment automounting only works if your logged in to a KDE desktop. That's no use to me as I want the disk to be used by automated processes when available.
How can I set the disk up so that it auto mounts when I plug it in regardless of whether there is an active desktop or console session. It should be able to handle being removed and then reinserted with out a reboot or without having to log on.
