MDADM: How To Mirror Installed LM 17 Disk

I just got a laptop with a 500GB hard drive installed with a clean copy of Win 7. I'm trying to shrink the windows volume from windows using Disk management and it's given me 230GB. There's less than 15 gig being used by the win 7 install. I want to dual boot but not if it's gonna cost me half the disk! I followed suggestions from he http://skimfeed.com/blog/windows-7-f...ize-shrinking/ which freed up all of 280MB. Can anyone suggest how I can get more shrinkage out of win 7?

first off, hello all, I'm Gimpacause and I am just starting to use Linux again after about 12 years

I recently bought a Backblaze storage pod and Installed 15x6Tb hard drives (in Raid6+LVM) using this guide


recently due to a faulty UPS and power issues at my place, i have fried the mainboard and boot drive

i dont have anything backed up from my previous Ubuntu install


i have replaced the boot drive installed Ubuntu 14.04 LTS (including MDADM & XFSProgs) installed a replacement mainboard (exact same model/revision) can please someone point me to a guide , or advise how i proceed recovering the raid & lvm so my data is still intact, I have not attempted anything yet for frear of data loss

if you require any logs/information i am hgappy to provide them

many thanks

i am very new to linux but i wanted to try it out, my main windows drive is tiny so i decided to format my usb hard drive and use that, first i tried to install ubuntu but i got a normal.mod not found error, so after some reserch and a grub reinstallation it booted once,

the next day however i got another error so i decided to switch to mint to see if it would work any better, but i'm still getting the normal.mod not found error.

i've tried a whole bunch of things like reinstalling mint and grub, boot repair, but nothing works, i'm kinda frustrated because i know it works because it booted up before but i just can't figure out how to fix it.

On my current system I have drives sda, sdb, sdc; 1TB, 1.5TB, 1.5TB respectively.
SATA drive a is where I installed the OS and the other SATA drives b and c are from an old system that was linux software mirror, something I was using to play and learn. Now I have added b and c to my current system and before doing so I stopped the mirror and removed the partitions. I added the drives to my current system and used cfdisk to create one partition on each and then mounted the new drives. I then run ls and I see bin/....etc. listed in the new drive. Is this normal or when I create the new drive partitions should I use Logical instead of Primary.

Is there a way to get my drives back to non raid that I have missed doing?

Thanks

I am installing Linuc Mint Rebecca on this computer: CPU: I7, motherboard: ASUS X99-A, HD: 2x 2TB, motherboard BIOS RAID1, so the total hard drive size is 2TB

While I was installing LINUX MINT on RAID1 hard drive, the installation system pop up ??? ???windows at Wher Are You step, after I click OK, jump to Installation Type, no matter which type I select: Erase disk and install Linux Mint or Someting else, ??? error message pop up at Where are you.

And if I click either of the two disk, it shows "Unable to mount location"

however, I can double click and see the content of RAID1 2TB disk.

Question: what's the problem of LINUX MINT installation on RAID1?

I've just started tinkering with Linux and have a question about installing it to my current machine.

I'm running Win 7 Pro and have installed Oracle VM Virtual Box on the C:\ drive which is a 256 GB SSD. I want to create a 15 GB virtual hard drive on a second internal hard drive that has more space on it, and install Zorin 9.1 to it. Currently my C: drive is about 60% full and I'd rather not fill it up past that.

So my question is: Can I run Zorin off of a hard drive other than the C: drive?

Thanks for your consideration.

A week ago, I realized that I could not boot live disks. At first, I thought that it was the optical drive not writing the disks correctly, but when I tried two live disks that I've used many times before nothing happened with those either.

I have CD/DVD drive listed first in my BIOS' boot order and I even tried selecting the optical drive in the menu when the computer started and it still does not boot a disk. Thankfully, my somewhat old hard drives are still chugging along but I need to be able to use a live disk, in case one or both die on me.

My question is, how can I know for sure what the problem is? Is there a way to test the optical drive (Samsung Super Writemaster - which has a bad rep)? Could it be my motherboard. It was bought new 2 years ago, and there are no other issues with it. Also, I have been able to create playable DVDs on my computer with the Optical drive that work perfectly on my Bluray player, yet I cannot play the movies or open a data disk in file manager on my computer. What does that mean?

I want to know that it's worth it to buy another burner, before shelling out the money when I'm already practically broke from Christmas gift purchases. Any suggestions on how to test the optical drive would be appreciated.

Good evening;
Following instructions on-line I attempted to create a bootable USB drive (32GB Sandsik extreme) with Linux 17.1 installed to enable a trial before attempting a permanent install beside windows 7 on a new computer with Win7 prof. installed.

On the usb I see a 4.0 GB area highlighted in G Parted but not accessible from the Linux file manager. This shows up as a ~1.4 GB sub-directory titled casper. and also as 4.0 GB 'file' named casper-rw. Can anyone explain what is the purpose of this sub-directory? The software I used to create the usb bootable drive and install Linux to is 'Universal-USB-Installer-1.9.5.9'. This is a windows executable. My intent was to create a bootable usb drive for Linux that also contained my required hardware drivers, etc. This doesn't appear to be working 100%; although Linux 17.1 boots the nvidia hardware drivers do not appear to be available even though I downloaded these and they are on the same usb. On boot-up a message box indicates that hardware acceleration is not enabled and higher than normal processor usage may occur.

Any assistance / direction, etc. would be greatly appreciated.

Regards;
Mike

Some weeks ago I installed Linux Mint 17.1 Cinamin. Yesterday I installed 17.1 KDE. Now I have an home directory with empty set of user folders. I did find all of my files under devices 129.0 GiB Hard drive, including the old Home folder. How do I get my old files back to where I can use them?

My attempts to back-up to an external hard disk finally met with apparent success but I cannot now mount the target drive.

To summarize:-
1. Installing a SATA hard disk, identical to my computer's main drive, in a USB 2.0 caddy and attaching this to the computer resulted in qualified recognition. 'fdisk' 'saw' both the main drive, as sda, and the USB drive, as sdb, respectively but initially noted that the latter, “... doesn't contain a valid partition table.” This was hardly surprising. At the point of first connection the external drive was essentially a 'bare metal' device, having had its data wiped. Nevertheless, 'fdisk' correctly reported its size, number of heads and cylinders, etc.
2. 'dmesg' also correctly identified the external disk as sdb, reporting its type and the USB port to which it is connected.
3. 'df' ignores the second hard drive, reporting only the main disk.
4. Attempts to clone/back-up the main disk to the external disk using the recommended tools EaseUS Todo back-up and RedoBackup, booting respectively from appropriate USB memory sticks, both failed. Neither utility was prepared to write to the external disk. EaseUS acknowledged the latter but crashed the whole computer when instructed to perform the clone. RedoBackup failed to recognize the external disk.
5. Then came the break-through. A bit more Net browsing led me to try the command 'dd if=/dev/sda of=/dev/sdb'. The main disk was bit-copied (cloned) to the external disk at roughly 20Gb per hour, meaning that my 80Gb disk was copied in just under 4 hours. Checking 'dd's resulting report showed what appeared to be a perfect copy.

So far, so good. I now have a back-up which, being identical to the main disk, should, I assume, be bootable. In the event of trouble with the main disk I should be able simply to exchange it for the external disk and carry on from the point at which I made my last back-up. I cannot, however, access and read the external disk. I assume that it must have a partition table and be mounted. The first requirement appears to have been resolved by the cloning operation. 'fdisk' reports no trouble with the partition table on the cloned external disk. It lists /dev/sb1 as the bootable Linux partition, /dev/sdb2 as the Extended partition and /dev/sdb5 as the Linux swap / Solaris partition, exactly mirroring the corresponding entries for the main, sda, drive.

My attempts to mount the external disk have all failed, however. I clearly do not understand the syntax of the mount command or have failed to meet some other requirement. 'mount' objected without hesitation to my early mistakes but “mount -t dev/sdb” was instantly accepted. No error messages or other output resulted and the command prompt was immediately redisplayed but 'mount' then failed to show that the external drive had been mounted. If I try something like 'mount -t /dev/sdb1 /mnt/xdisk', where xdisk is a directory I have been told to create, then I am presented with a prolix description of 'mount's syntax, most of which leaves me bewildered. 'mount' then once again confirms that sdb1 does not feature in the list of mounted devices.

Can someone offer any suggestions? I have read one or two of the other posts on this topic but none of the details match my problem too well and I did not understand some of the replies. If I try to add a line to /etc/fstab, for example, I find that I do not have a directory called 'fstab', only 'fstab.d' and that is empty.

I have roughly one year's experience with Linux Mint 13 which I chose because it so closely resembled Windows XP.
