Hardware :: Failed Hardware Mirror Disk- Convert One Drive To Non-mirrored?
Aug 30, 2010
I own an Iomega NAS enclosure. It is basically a card with 2 sata drives attached and a network card that runs an small web interface. To make a long story short. The controller card has went bad. One drive dropped out of the mirrored set.... and then came back in and attempted to rebuild. Several hours later the drive dropped out again. I attempted to replace the drive and the controller would not rebuild at all.
To summarize. I have accepted that the controller card is toast and want to proceed assuming one drive is compromised and the other still has salvageable data (About 18 GB needs recovered) I took the presumed "good" drive.. attached it to a standalone enclousre that takes it from sata to USB.When I look under disk manager (using Ubuntu 10) I see the following appear
1) the multi Disk device appears indicating it is part of a logical drive. Indented from that is
2) The "Array" Icon
3) The USB icon indicating a "peripheral device" Indented from that is
4) the Drive as a 500 GB hard disk (correct)
when i click on 4) I see 2 volumes 1 1GB volume with partition type Linux (0x83) and a 499 GB partition with the same type (0x83) However..because it thinks it is part of an array it is not mounting. HOW do I tell this drive "you are not in an mirrored array anymore...mount as a single drive"

Was wondering if it's possible to set up a single disk with btrfs and then later on convert it to a 'mirrored' array?

I've installed Debian Squeeze twice using CD1. First time with a high-speed internet connection using a mirror, 2nd time without. With a mirror, much more is installed, and clearly a much more complete installation. What packages would I install to make a basic CD install more like a mirrored install? Is there a list on the CD somewhere?

I have an internal hard drive split between Windows 7 and Fedora 12. The Fedora 12 install exists on a LVM which presents a bit of a challenge when trying to mirror the drive. I was trying to use gparted but it doesn't have support for LVM. I discovered g4l, which does a bit-by-bit copy and ran a full disk copy using that from the 500 GB internal to a 500 GB external. Inspecting it with gparted, the copy LOOKS like it went correctly.
However, when I disconnect the internal and attempt to boot to the external (specifically in the BIOS), it's unable to boot to it. It instructs me to insert bootable media and try again. Has something gone wrong with the copy? It SEEMS like g4l finished faster than it should have given the copy rate it was operating at (I had figured out when it should finish up), but the screen saver had been on and when I came back it was back at the menu, so I don't know if it got to 100% or ended prematurely? There were certainly no error messages...

Have just installed Ubuntu Server 10.04 on a dell with a perc 700 raid card. Running a mirrored raid1 (2x 500G as one drive). All went well. Have installed a basic Gnome front end and Webmin. I want to partition the hard drive into system and data storage areas. What is the best way to do this with a mirrored RAID system?

I have some servers running rhel5,they are in mirror disk 2 disk there is no any hardware RAID only software RAID and they in remote place.
Assume RHEL5 hda(Disk1) & hdb(Disk2) currently in mirror, i have to install some patches in it. Before that i have to break the mirror and boot from hdb if it is successful. then i have to apply the patches to hda.
After that i have to boot from hda and check whether the latest patches updated and working fine. finally i have put them in mirror. the same scenario for solaris.

I've got a new server built, shaken down and patched (2.6.18-194.el5). Works nicely.
I don't want to rebuild it from scratch if the root drive goes belly up, but I do NOT have a hardware raid controller.
The root disk should be pretty static at this point... any suggestions how I might back it up?
I was thinking I could put in another disk (same size or bigger) and use cron to run something like this nightly: dd if=/dev/sda1 of=/dev/sda2

Looking for a few pointers here.I am trying to automate the adding and removal of two external usb disks to my linux raid mirror (md) that I use for an offsite copy of my data.This is what I currently do.Server has 2 x 500 gb internal disks setup with linux raid 1. (md)I connect 1 of the external usb disks, add it as a secondary mirror to the main array.After it rebuilds, I remove it from the array and take it home.I have two of these external drives so one of them is always offsite, and the other is either being rebuilt, or connected as a secondary mirror.At the moment, this involves running commands manually. I cannot seem to figure out how to automatically add these disks from and to the array with a script. It seems that every time it rebuilds on the external disk, it gives it a new UUID.

At the Get Slackware page at the Slackware website it gives a list of addresses which when I click one of the addresses it redirects to another page with a list of mirror images. Which address and which mirror image do I need to work with Kubuntu 11.04 on my netbook so I can create a USB startup disk? With my connection speed these mirror image downloads take about an hour and a half and I cannot just be guessing which mirror image to download.

I recently made a script to automatically download a directory from my webserver using ftps (required by hosting company). It seems policy has changed again or something, because trying to download files gets the following error:
mirror: Access failed: 521 Data connection cannot be opened with this PROT setting.I can access the files just fine with Filezilla, but not lftp. I didn't change the code, but here it as anyway:
lftp -f ~/the/file/below
Quote:
open -u USERNAME,PASSWORD DOMAIN
lcd /local/place/to/put/files
mirror
quit
I tried manually, login works fine, but nothing can be done after that.until this works again I've broken a backup system of mine.

I have set up a Ubuntu box that is a proxy server. Everything works great and I would like to somehow make a complete disc backup of everything on that hard drive, incase it fails. Took me quite a while how to figure out everything and get it working. The box has an 80gb drive, with Ubuntu 9.10 loaded, standard default setup. Could I just install a 2nd hard drive and somehow give it a command to mirror everything to the 2nd hard drive?

I have a running RHEL5 system, which has two physical disk drives, but is currently running on a single drive of the pair. The single drive the system is running on contains a root/boot partition and a swap partition. I would like to be able to add a mirror drive to this existing setup without having to disturb the running system (much). That is, I don't want to have to completely dump, reinstall (creating the mirror on the way up), and reload from backup media if I can avoid it. I have seen procedures that go as follows:
- the "extra drive" (the one not being used as the current root/boot device) is first brought under LVM control as a root object with one physical mirror attached.
- the data from the running root/boot drive is rsync-ed over to the LVM-controlled half-mirror, and boot records added.
- System rebooted on newly created half-mirror.
- Original root prepped to be second side of LVM mirrored root, and is added in.
Can one boot from an LVM disk directly? There seems to be some question on this that came up in other lists I had read online.

I installed Debian on my PC with a Acer Stock motherboard (xc600) with amd64 and after the installation finished it told me to remove my installation media and reboot. After reboot I was returned this message ' ERROR: No boot disk has been detected or the disk has failed.'. I have verified with gparted using mint live OS that I have Debian installed on my system.
I got believes that this may have be caused by a broken grub or I need to configure something I don't know how in BIOS.
I will update the topic later..
My installation media was a USB 2.0 flashdrive with a Debian 8.2 Jessie Installer and 9 different Linux distros. I have installed Debian multiple times before on my laptop and never had this problem so I know how to go through the installation process and set the partitions.

I also tried to install virtual pc and get not boot disk found.

I am from India, and I tried to update my Ubuntu system today. Code: $sudo apt-get update The update failed because the connection to the India mirror timed out: Code: [URL] Could not connect to in.archive.ubuntu.com:80 (111.91.91.37). - connect (110: Connection timed out) I tried the update a few times, with the same result every time.
I had firestarter running at this time, and noticed that I would get new security events every time I tried an update. I checked the events list, and it turned out that the machine at the ip address 111.91.91.37 (the in.archive.ubuntu.com machine, to go by the above error message) had been trying to make connections to seemingly random ports on the machine every time I tried the update: see the attached screenshot. I then changed my repositories to the Main Server using Synaptic, and tried the update again (from the command-line). This time it worked without a hitch, and firestarter did not report any unwanted incoming connection. why is the India mirror trying to open connections that the Main server apparently does not need in order for me to do the update? Should I (we) be concerned?

I know you can fail and then remove a drive from a RAID5 array. This leaves the array in a degraded state.
How can you remove a drive and convert the array to just a regular, clean array?

Ive 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 have a bunch of disk images, made with ddrescue, on an EXT partition, and I want to reduce their size without losing data, while still being mountable. How can I fill the empty space in the image's filesystem with zeros, and then convert the file into a sparse file so this empty space is not actually stored on disk?
For example:
> du -s --si --apparent-size Jimage.image
120G Jimage.image
> du -s --si Jimage.image
121G Jimage.image
This actually only has 50G of real data on it, though, so the second measurement should be much smaller.
This supposedly will fill empty space with zeros: cat /dev/zero > zero.file rm zero.file But if sparse files are handled transparently, it might actually create a sparse file without writing anything to the virtual disk, ironically preventing me from turning the virtual disk image into a sparse file itself. :) Does it? Note: For some reason, sudo dd if=/dev/zero of=./zero.file works when cat does not on a mounted disk image.

I have a very old laptop with no CD and no Floppy and a BIOS that won't boot from a USB device.I wanted to install Ubuntu on it though so I pulled the hard drive and connected it to my Macbook via a USB-to-PATA adapter. I booted the Macbook off the live CD and tried to install Ubuntu to the USB drive but the install wanted to update the boot partition on my Macbook which I would prefer not to do (I run Ubuntu on the Macbook in a VM). Instead, I used the Startup Disk Creator in Ubuntu 10.04 to make the hard drive from the old laptop an Ubuntu Startup Disk. I put it back in the laptop and it works fine, but when you boot it asks if you want to install Ubuntu and of course you can't because there is no available disk.
I thought about pulling the drive and doing this all again but splitting the drive into two partitions so I could make one partition the startup disk and install to the other, but I was not sure this would work. The disk in question is only 12 GB so I don't have a lot of space to work with. Also, this particular laptop is a huge pain to get the drive out of so if I can somehow fix this without removing the drive again that would be awesome. If there was some way to just convert the startup disk to a "regular" installation that would be ideal.

I kept my movies on a 2 drive software raid1 mirror, but now I changed my mind about needing a raid and pulled one of the drives for another use. Can I convert the remaining raid drive back to a regular single drive and keep the data in place? Can I change the raid partition back to regular partition and be able to mount it?
