General :: Restore Data From A Set Of Old LVM Disks Using Images?
Aug 6, 2011
I have three hard drives that were previously in a Debian server setup to use LVM that I now need to access data on. The first hard drive had a boot partition along with an LVM partition, the other two hard drives were also LVM.From what I remember I have to mount all three at once for LVM to function correctly but I don't have available hardware (particularly a motherboard that can mount all old IDE).Can I use a USB<->IDE converter to image the disks, and then mount them?What Linux distro should I set up to recover the data?ow do I know what version of LVM is needed?

I regularly take pgdumpall from production database and restore staging database. Production database size is 4.5 GB. After restoring the staging database size is incremented.
The following command is used to restore pgdumpall file.
psql -U postgres -f dbdumpall
My aim is to sync up production database and staging database.

I am a fairly experienced ubuntu/linux user. But i can't seem to fix my current system, and i really dont want to reinstall as of all custom software i use.My main goal was resizing my / paritition with gparted. THe tutorial said to remove the boot partition (200 MB EXT4) and remove the SWAP, and then resize the partition. THis all worked out well. After booting a live CD i reinstalled grub. Try to boot and it drops me to the grub shell.I tried several things, like reinstalling grub. But this is not the problem. The problem is my /boot only contains a grub directory. No bootimages or configfiles whatsover.Is there a way to restore these like redownloading an image or putting in a apt-get command to download a new config?

I've recently started using Ubuntu as my main desktop operating system and I'm looking for a backup solution that is able to backup not only my documents and various other files that I have on the system, but I also need it to backup and create restore images for the operating system.

I'm browsing on my phone which is not letting me scroll to the end of this text box so I will say thank you in advance for any replies now.After my computer was switched off abruptly after a power outage I have many errors upon booting. My hard drive setup consists of a RAID0 array of two 500GB sata disks. The partition table (from my head!) goes like this:50GB NTFS Windows XP /c/50GB ext4 Ubuntu 9.10 /4GB swapThe rest is a large NTFS partition all the way up to the end of the array at 987GB. Mounted at /media/share/I am thinking I will have to start again (I won't lose much, I have recent backups), but what is the best way of restoring the system as much as I can? Currently my computer has been booted into Ubuntu for over an hour, and after pressing ctrl+alt+shift+F2 I can see that it is finding errors still, now at sector 6008. Should I let this run its course or REISUB it and boot onto a live CD. I think the main problem is with an NTFS partition

My machine has 4 SATA 2 West Digital 1TB disks. I made 2 partitions on each of them, 500GB for each partition. When I started using them I check their I/O using iozone. The first partition has 100MB/s for read, 70MB/s for write. And the second partition has 80MB/s for read, 55MB/s for write. All 4 disks has the same result.
As I use on, the I/O speed on each partition decrease, to different extend. For example, for the 4 first partitions, the write speed varies from 69MB/s to 56MB/s. And I have same amount of data on each of them, all used 11%.
My guess for this is the disk block allocation policy. This is caused because some disk starts writing from inner location while others writes on the outer edge, even though amount of data on each disk is the same.

I am starting to use Shotwell for my photo management in lieu of DigiKam. One tool that I liked in DigiKam which does not seem to be present in Shotwell is the ability to add/edit geolocation data. Is there anyway of working with geolocation data from within Shotwell?

I have a weird problem I am experiencing with my Apache 2.2 w/ ISPConfig 3 running on Debian 5.0.4. It is not a website html issue.***PROBLEM***Images are not beind displayed,javascripts are not being run, however when the site is viewed from a local source as a file(like on a USB Flash Drive) they work fine and display properly.Here is the website URL:I have removed a lot of the images and content or changed it in order to troubleshoot it myself, so the site is stripped pretty bare. There is supposed to be a logo inside the "header" <div>, which is set in the CSS file "style.css". There are supposed to be images for navigation, but they show up as red "x"'s. I removed the javascript elements and just trying to work with barebone html/css and can't seem to get it to display properly.

I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.

I want to buy another laptop. I want to use FC on it. I need bluray because I want to save data on bluray disks of 25 gb (better than dvds, more space). I have one option, a fujitsu that has bluray writer, big display (I have another one, other model, same size and it's working fine with Fc14, only some small issues).
Second option is a Dell (I had an older dell inspiron before, which worked fine with FC), more expensive, lacking a writer, but it can read bluray. If I take this, I would have to also buy an external bluray writer. Has nice specs, but I am really worried about the graphic card, whether I can make it work with Fc14. I saw some people having problems with linux and this graphic card, while searching on google.
Here's specs for both (sorry for the language from website, but I found in English other specs than these, I guess the specs can be read easily): Dell XPS L702x and FUJITSU Lifebook NH570 I am inclining more towards the Fujitsu, but haven't decided yet.

I am just spent half an hour hunting for a thing that should be totally available already:USB install images of Ubuntu, knoppix and all the others.And, the only good way are so far complicated tutorials where you extract the stuff from an CD image. Why??Hasn't everybody notices that CDs/DVDs are vanishing big time? That more and more systems don't have the readers anymore? Instead of following a 10 point instruction list, it would be nice to just be able to download a Ubuntu 8.10 or whatever USB image and be able to beam that DIRECTLY to a USB stick with a dd command.
Or am a missing something here? Does this exist?It should by no means be mariginal, considering how important USB stick in specific and flash memory in general have become.

I've got a raid5 array of 4 disks with ubuntu 8.04 runing on it that is currently still working:
/dev/sda
/dev/sdb
/dev/sdc
/dev/sdd
Smartmontools for /dev/sdc tell that there are 9 sectors pending for reallocation:
Code:
197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 9
198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 9
And /dev/sdd has increasing number of reallocated sectors (about 1 every couple of minutes):
Code:
5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 1735
/dev/sdc has failed a coulple of times this week (but I have always sucessfully readded it to raid5) . But the increasing number of reallocated sectores on /dev/sdd concerns me even more.
I'm affraid that during removal of /dev/sdd and adding new /devs/sdd disk, raid might fall appart. That's why I would try to do it in Ubuntu Live CD:If the raid falls appart (/dev/sdc fails) during the readding of new /dev/sdd disk, I might still remove the new /dev/sdd and return the previous one and assemble the raid with:
/dev/sda
/dev/sdb
/dev/sdd (old one that was previously removed)
Does assembling Raid in Ubuntu Live and adding new disk for /dev/sdd write anything on /dev/sda, /dev/sdb and /dev/sdc in the process of adding /dev/sdd into raid5?

I have two disks from a old computer (now it doesn't exist anymore). They were in raid 1 with this configuration:
Code:
----------------
| disk 1 | disk 2
----------------
| OS
----------------
| |
| raid 1 | raid 1
| |
----------------
There is probably an error in one of the two disks, however raid 1 should allow we to restore data. So now I can physically mount this disks on a machine with ubuntu (ubuntu is on another disk). My question is: how can I restore data from disks? I think that using mdadm is not enough.

I have just foolishly used live media to install F14. Pre-upgrade of F13 to 14 repeatedly failed. Sadly I used the use all available space option rather than the free space. As a result I have a working FC14 system but no data from my F13 installation. Is there any way to restore my f13 system and/or data?

Ive installed ubuntu for the first time today, i have a hdd of 500gb, that had 65gb occupied with music, movies and games.
What i did during installation:
it asked me where to install it, so i created a new partition of 100gb ext4 type, to install it there, and i was going to leave the rest for the data, but it wont let me do it, so i went back and selected the "exchange type swap linux 0x82 type" for the 400gb partition.
Then installed it, and now i cant find my data, and i have only 100gb of space in the hd, if i use the "disc utility" i can see the other 400gb, and change partition type, but i dont want to lose my data..

I've occasionally changed HDD filesystem type in Disk Utility from NTFS to Linux Extended . It created an extended partition containing some other partitions instead of NTFS.

I'm using Webmin, and Webalizer plugin. Days ago, webalizer works fine. But starting from yesterday, Webalizer no longer generate reports. And when I try to generate report manually using webmin, I get this message: Code: Running Webalizer to generate report from [URL]..
.. Webalizer failed! See the output above for details. Because I didn't get any details on that message, I run webalizer manually using command:
Code: # webalizer -n mydomain.com And as result, I got this message:
Code: # webalizer -n mydomain.com Error: Unable to restore run data (10) I have few domains in this machine, and for all domains I got the same result. Anyone has any idea(s) about what happened and how to cure it? Few days ago I think I tried to install Perl-Small-XML using CPAN and failed. And I installed awstats too. Don't know whether it's related or not.

This is to request assistance or information as to why the evolution application will not accept the evolution-backup-tar.gz file from a previous version.
Situation: I upgraded by way of a fresh install from openSuSE 11.2 to 11.3 (GNOME desktop).
Before upgrading, I produced the above mentioned backup file so that I could import all the mail, addresses etc. into the new application.
Result: it does not work. The process starts up seemingly normal but then simply sits there forever with the message "evolution shuts down" - but it does'nt. I have to kill it to stop it.
I am looking forward to a resolution since it would be a real pity if I lost the mail history.

I was putting the cover back on my Antec p180b, and I guess it got stuck and gave it a hard bump (pretty much broke the cover). As a result, one of my hard drives, a Seagate Barracuda ST3750640AS, got messed up or something. All the other hard drives are fine. It's in an LVM with another hard drive, so now I can't boot up into my computer. So I booted into the installation CD:
Code:
# find /dev/sd[a-c][1-3]
/dev/sda1
/dev/sda2
[code]....
This led me to believe the partition was messed up. So I ran cfdisk, and it said something about a missing partition table or something. Additionally, instead of showing the single partition on it, it displays, from my recollection, Pri*Log. To my knowledge, this is the only problem with the hard drive. So now I need to either somehow create or restore the partition table without overwriting the data. Or get a new hard drive, and some how recover the data (LVM, partitions, and all).

i'm wondering if it's possible to restore the original image file that you have hidden data in with steghide. The basic Idea is you have a photo using gpg sign it and then embed the signature. then remove the signature at a later time and check it with the signature. I hope another "inverse" algorithm doesn't need to be written to undo the first (if a "inverse algorithm is possible). This assume you already have the pass phrase or that there is no pass phrase. I already know how to retrieve the original file just want to remove the hidden data from the Image and restore it's attributes.

I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);
dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)
(a new server,2 CPU 8 core and 8 gb ram)
1000000+0 records in
1000000+0 records out
1024000000 bytes (1.0 GB) copied, 12.9662 s, 79.0 MB/s (I have not used this server yet) (hw raid1)

I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?

I am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.
