Ubuntu :: Removing Test Drive Keyring Authentication?
Mar 13, 2011
I have been attempting to load the latest version of Shotwell only to find that it is not available on 10.04. Consequently I attempted to load 10.10 and found that it would not load from my DVD. Similarly 11.04 fell at the wayside. Tried downloading both OSs again and again but each time failure to load.
Having come across reference to test drive I thought that I would give it a go and followed the instructions on this. It appeared to download OK but then would not display the OS. Decided to remove but despite it appearing to be removed (from the information displayed in the terminal) it still is loitering on the menu.
Since that failure I think that it could be related I am now being continuously asked to authenticate the keyring, something that from my initial install I have never needed to use.

I have a seagate SATA hard drive that was running a mythtv distro. It had 3 partitions, EXT3, swap, and XFS. I started having I/O errors on boot and saw error messages on both the EXT3 and the XFS partitions. I also heard some clunking sounds on the drive when it was reading, so I thought hell, the drive is dead.
I have since replaced the drive and everything is back up and running on the replacement drive. I thought hell, the seagate drive is toast, but I just want to verify it with some sort of tool. I have the hard drive in a Vantec NexStar external hard drive case (SATA->USB) and found there was a tool called badblocks. Ran badblocks on it, which ran for 24ish hours and found no bad blocks. I also didn't notice any clunking sounds while it was running.
I ran
Code:
badblocks -n -v /dev/sdb
Is badblocks a proper test to run on external hard drives or was I just wasting my time? Is there any way that I can really test it without removing it and connecting it with SATA to the motherboard?

I want to remove/disable keyring. I want it to still save my passwords but not ask for a master password on boot. I am using 10.4 but it probably works the same...

am currently using Windows 7 across my networked PCs at home.
I've just received my new Samsung N250 Plus Netbook which comes with Windows 7 Starter (yuk). I read a post on Ebuyer from someone who has installed ubuntu on his N250 so thought I'd give it a go tonight.
My main concern is whether my wi-fi card (Broadcom 802.11n according to windows) will work when I remove windows and install ubuntu. I intend to use the netbook for internet use only while working abroad.
Is it possible to test it works by running ubuntu from my USB stick first (without removing windows 7)?

I bought a new 1.5TB SATA drive (WD15EARS), now I intend to thoroughly test it for bad sectors and other issues, before it will become part of a server raid array.
Are there any good testing tools out there to perform read/write compare operations allover the disk space?

I installed Ubuntu 9.10 on half of my D drive about a year ago, but realized that I don't really need all the space on the Ubuntu partition. I have Windows Visa Home Premium installed on my C drive. Is there any way to re-size the drive on which I had installed Ubuntu without removing it?

My little server box running 11.04 currently has two drives configured in a LVM, a 160gb internal drive and a 1tb usb drive.I have three logical volumes root and swap on the 160gb and backup on the 1tb. I am going to be changing the internal drive for a 8gb SSD and would like to keep the data currently on the external, is it possible to do this?

I notice a bunch of weird what appear to be hard drive related error messages on my Linux server:
May 16 19:07:38 ghost kernel: [ 3495.452698] ata3.00: configured for UDMA/33
May 16 19:07:38 ghost kernel: [ 3495.452706] ata3: EH complete
May 16 19:07:40 ghost kernel: [ 3497.380640] ata3.00: configured for UDMA/33
[code]....
I don't know if this could be an indication that my hard drive(s) are about to fail. Can someone tell me if there's a way to test the drives or understand what's causing this error?

I was unable to boot my computer because bad blocks in my drive 'appeared' over my current and most used partition, for 9.10. I discovered there were 101 bad blocks on the drive, so I called western digital and had them send me a new one. In the meantime, running fsck on the drive managed to sort out the bad blocks for the time being. The replacement drive arrived on Friday, and since then, I've been trying to clone my current drive to the replacement. Using Clonezilla, I kept getting the error "bad partition table on /dev/sdb". Alright, I tried a bit-by-bit transfer using dd, but for some reason, the transfer fails on the last partition, leaving the replacement drive unbootable. What do you think I should do? Does it sound likethet sent me another faulty drive, or am I just doing something stupid? I've copied my drive before, but ive never had these problems- i just popped in Clonezilla and away it went.
I'm really leary about this drive, I have many important files for school and TONS of music. The school files, I can back up, and the music could be shuffled to another external drive, but I reallydo no want to go through all of the time and effort to move it to a new drive that may already be failing. Does anyone know what I should do? Is there some way to test the 'health' of the drive before I spend hours rebuilding my filesystem?

A few weeks ago, I installed Ubuntu 9.10 on a Dell Insprion 8600 as a dual boot to try out Ubuntu. I let the setup configure partitions for me. During the install, I was asked once for a password. Last week, Win XP would not boot up; that's OK as I was planning a re-partition and reinstall of both win and Ubuntu.
I wanted to get files off the NTFS partitions (I have one for win, one for the swap file and two more fore files etc.), so I wanted to mount the NTFS partitions. I was asked for a password for the administrator. My regular password, the only one I have set up, would not work. I tried rebooted two more times and still no luck with my only password.
However, I was able to boot up from the set-up disk and mount the NTFS partitions without a password. I was able to move all the files I needed to one partition that I plan to keep (I will reinstall win xp then back up those files on the separate partition).
A question and a comment...
1. How do I install Ubuntu so that I make sure I have the passwords to do administrative level things (like mounting a drive)?
2. Being able to do administrative work off the Ubuntu test-drive disk while being denied access after signing in seems like a security issue (unless I screwed up somewhere).

The disk I obtained from a seller runs fine in live mode (no installation) on my Windows XP. I liked what I saw. However, when trying to run cd live on my Linux PC it won't run. Linux pc currently has Kubundu 9.1 installed. Previous to that I had Mint 8 installed, but again Fedora 12 cd would not run. After getting an initial Fedora startup screen, I next receive a bunch of text, ending with a text screen of about 30 lines with "OK" in green to right of each line. At bottom is blinking cursor. That ends my machine's live running of cd.
Obviously, if I can not get cd to run live on linux pc, I'm not going to be able to install. (I should add that ubuntu, kubuntu, mint 8 and pclinuxos all ran successfully live on machine and three of them were installed successfully.) Perhaps, Fedora is at war with Ubuntu et al.

The search function does not like "U3" so I cannot locate the latest in removing it. Has anyone figured out how to do so using Linux? (Explosive, maybe, but was the Stupix worm hidden in flash drives using the U3 tools?)

I did an installation of SUSE 11.2 on a new SCSI hard drive. Keeping the old hard drive separate. I remembered there was some info on the old hard drive I wanted.
I added this to the system and mounted a partition. I then copied the data over. Then I umounted the partition rebooted the machine and removed the hard drive.
However the machine will now not boot without this hard drive even though its not mounted. Not sure what the error message im given means I think it could be trying to fchk it.
Do I need to do something more like remove /dev/sdd ?

I have a flash drive that I used on my old netbook to temporally hold a copy of ubuntu as the netbooks internal drive was dead. I have since got a new netbook and wanted to return the flash drive to simple removable storage. I've re-partitioned it back to 14gb fat32 2gb ext2 and everything is working fine. Except that if I try to boot with the key inserted grub loads then errors imminently (sort of obvious if grub is still in the MBR but there is no menu.lst file anymore...) Googling for removal of GRUB just gives me loads of hits for how to restore windows mbrs when you dont want to keep linux anymore. None of these methods seem to have any targeting. I need to remove grub from sdb while keeping it intact in sda. sdb shouldn't even be bootable, so that when boot from usb is higher in the bios than boot from hdd the usb key is ignored and the hdd is booted as normal.

Server (LVM):
500GB
320GB
I want to install a new 500GB and remove the 320GB, of course moving the data on the 320GB to the new 500GB. I have an external 1TB in enclosure that I can plug in to move the data over, but how do I move only the data on the 320GB to it?? I found this [URL]. But that is only to move the data to a new replacement disk, but my external is only temporary to move the data from the 320GB until I remove it+install 500GB, then move the data back. Not enough space on the 500GB already on server to move everything from 320GB to it, just in case that seemed the obvious thing to do.

I'm dual booting Ubuntu 9.10 and win7. I have an NTFS partition on my disk and whenever i want to browse files on that partition I'm required to enter my password. my problem is that my music folder is located on that partition, and as a result, whenever I open rhythmbox, it cant access the files on that partition and begins to remove them from the library. in order to prevent this i must browse to that partition manually and enter my password upon request, prior to opening rhythmbox.
on a side note - shouldn't the spell checker on the Ubuntu forums recognize "Ubuntu" as a legit word ?

I'm looking for a way to quickly remove all data/partitions/boot records from my hard drives while running linux (distribution is irelevant). There are lots of ways to do this that I know of, but they all have some problems. Here's a list of what I've tried/thought of already. The most obvious is fdisk: Simply delete all the partitions. This usually works just fine and is very quick, but there are times it just doesn't....I'm realy not sure what gets left behind...I remove the MBR as well..but whatever it is, it's in the way. A couple other options are:
dd if=/dev/zero of=/dev/sdb bs=1M
shred -vfz -n 1 /dev/sdb
Both of these approaches are great if you're selling the components and want to make it very difficult for anyone to recover data. The draw-back is they take so very long to run. I've got four 1.5 TB drives that I've been writing zeros to for 2 days now. If you thought watching grass grow or paint drying was boring. A hundred years ago or so, when I was doing tech support for Windows 95 users we used this nifty dos-based debug script to wipe the hard drive. It was sort-of a last resort thing, but it worked beautifully, most of the time. If the customer had already formated, fdisked, fdisk /mbr, reinstalled Windows, but still couldn't get the thing to work, this would clean the drive so you could do a fresh install.
Just in case someone wants this, I'll post it. To use: first boot to some type of DOS environment in which you have the program "debug".
debug
-F 200 L1000 0
-A CS:100
xxxx:0100 MOV AX,301
xxxx:0103 MOV BX,200
xxxx:0106 MOV CX,1
xxxx:0109 MOV DX,80
NOTE: Type 80 for the primary hard drive - HD 0,
or type 81 for the secondary hard drive - HD 1.
In most cases, the primary hard drive is required 80.
xxxx:010C INT 13
xxxx:010E INT 20
xxxx:0110 (Leave this line blank. Press the <Enter> key to continue.)
-G
The message Program terminated normally appears. How to do something like that while running linux?

After a couple of years, I decided this weekend to replace my old slackware 10.2 with the latest stable version 13.1 64 bit. The change log tells me that with the new kernel 2.6, the old IDE/ATA system has been removed and the libata is used instead. That /dev/hda become /dev/sda and so on. No problem sofar, however ...
My FIRST hardware configuration was:
One SATA drives connected to the onboard SATA controller [A]
Two PATA drive connected to PCI IDE controller 1 [B & C]
Two PATA drive connected to PCI IDE controller 2 [D & E]
One PATA drive connected to the onboard IDE controller [F]
So initially the system had 6 disk drives. Booting from the Slackware install dvd, I found out that the drives are detected in the following order.
Onboard SATA controller
PCI IDE Controllers
Onboard IDE Controller
And the drives are get names in the following order:
/dev/sda : SATA disk @ Onboard SATA controller
/dev/sdb : first PATA disk @ PCI IDE controller 1
/dev/sdc : seconde PATA disk @ PCI IDE controller 1
/dev/sdd : first PATA disk @ PCI IDE controller 2
/dev/sde : seconde PATA disk @ PCI IDE controller 2
/dev/sdf : PATA disk @ Onboard IDE controller 1
sda upto sde are configured to us with LVM, so 4 disks are added to the volume group.
sdf is where Slackware is installed (sdf1 = swap; sdf5 = /boot; sdf6 /; sdf7 = /usr; sdf8 = /home; sdf9 = /var; sdf10 = /tmp)
Here is the problem:
When a 7th disk is added (another SATA drive @ Onboard SATA controller) then all names are changed like:
sda remains the same
sdb new added SATA drive
sdb -> sdc
sdc -> sdd
sdd -> sdf
sdf -> sdg
Obviously booting without LILO parameters results in a kernel panic, so I booted with: Linux boot=/dev/sdg root=/dev/sdg6. This does not give the kernel panic, but results in an option to check a drive and gives an option ctrl+d to boot normally. However it reboots and I get stuck at the same again.
How does LVM handle the naming shift of the drives? The 4 drives that are part of the volume group contain critical data!!! If needed, I can reinstall Slackware again from dvd with all 7 drives attached (to avoid naming shift), but how do I recover my volume group? What if one of the drives dies or is removed, then naming shift happens again.

I have a 7.9 TB logical volume I've created from 8 1 TB RAID 0 devices. The volume is formatted with XFS so I can resize when ready. However, I think I want to do something that is not possible. I have 2.5 TB free on my logical volume. I'd like to shrink the volume down to be 6 TB by getting rid of 2 of the 1 TB devices in the physical volume. However pvmove seems to require free extents in order to work. Do I need to add 6 TB of storage, pvmove everything onto it, and then decommission the original 8 1 TB physical devices from the volume?

I have a nightly scheduled script which creates a $vhostname directory under /mnt, mounts a windows box pointing to /mnt/$vhostname then rsyncs (pulls) some files/folders from the mount point. After this, I want to unmount the drive and remove the /mnt/$vhostname directory. Problem is that removing the /mnt/$vhostname directory sometimes ends up deleting all the files on the source! Example of script (stripped out lots of superfluous stuff):
Code:
vHOSTNAME='testhost'
vRSYNCFLAGS='-ahvz --inplace'
/bin/mkdir -p /mnt/${vHOSTNAME}
/usr/bin/rsync ${vRSYNCFLAGS} /mnt/${vHOSTNAME}/KAVSHARE /backups3/${vHOSTNAME}/
/bin/umount -l /mnt/${vHOSTNAME}
/bin/rm -Rf /mnt/${vHOSTNAME}
It seems that my umount line isn't disconnecting the mount, leaving the following line to literally delete all directories, recursively. Is there a way of safely just deleting the directory (ie: mount link) without linux accidentally trashing the whole source?
