Adding a USB HDD to a VM via OVM - /dev/mapper Error

Hey all,
we're trying to hook up a USB HDD to a virtualized database server for a one time backup.
So after connecting it to the OVS, i formatted it to ext3, mounted it and voila. When i edit the database VM via OVM i can add a Physical Disk.
I am getting an error though:
Status: org.apache.xmlrpc.XmlRpcException: exceptions.RuntimeError:disk:setup_error:Command: ['xm', 'block-attach', '0004fb000006000056a65a591c902757', 'phy:/dev/mapper/35000000000000001', 'xvdd', 'w'] failed (1): stderr: Error: Device 51760 (vbd) could not be connected. /dev/mapper/35000000000000001 does not exist.stdout: Usage: xm block-attach [BackDomain]
...and he is right. There is no /dev/mapper/35000000000000001
But where does it get that information from?!
Any ideas?

OVM will only make use of volumes that are accessible through /dev/mapper. USB volumes are, as you already know, not available in /dev/mapper and thus can't be mapped to virtiual machines as volumes.
This is a limitation, but I think Oracle decided for this, because a USB drive really doesn't make a good choice for a virtual drive, as is introduces a lot of latency and other potential I/O issues, you don't want to have in a virtualized environment.
It would be better to map the backup drive in thge guest itself using other protocols like NFS.

[SOLVED] external USB HDD fails to install arch w/boot device ERROR

I've been working on installing arch linux via an external USB harddrive (specifically seagate free agent go 320GB) for 1 week now, and everytime I failed - until TODAY! thankfully I found this post, where user Dieter@be references this link, which displays BUG ID#17231 at the top titled "Can't boot LiveCDs 2009.08 (/dev/archiso doesn't show up)". the bug report states ::
I can't boot the LiveCDs 2009.08, neither netinstall nor core.
When it tries to access /dev/archiso it shows these messages:
:: Waiting for boot device ...
Waiting 30 seconds for device /dev/archiso ...
ERROR: boot device didn't show up after 30 seconds ...
Falling back to interactive prompt
You can try to fix the problem manually, logout when you are finished
ramfs$
reading further thru this bug report, I found a very insightful post by Heiko Baums (cyberpatrol) where he says the following, and I quote ::
Problem found. The link /dev/archiso wasn't created.
After
ramfs$ cd /dev
ramfs$ ln -s sr0 archiso
ramfs$ exit
it continued booting correctly.
And sg was also loaded after this. ;-)
as you see, the bug report was for the CD version, not the USB version - yet, my issue with the USB bootdisk was the same, (no matter which boot disk I tried = netinstall, core, .img, .iso, etc) meaning I got the EXACT same error = "ERROR: boot device didn't show up after 30 seconds ..." ! well, I figured that I'd try one of the new fancy ISOs found @ http://build.archlinux.org/isos/ - specifically I use/used archlinux-2010.03.04-netinstall-x86_64.iso.
upon running Unetbootin from windows 7, and choose to install the ISO archlinux-2010.03.04-netinstall-x86_64.iso to my first partition on my USB harddrive (that first partition being FAT32, and had already been set as bootable previously), that completed successfully. I rebooted, and choose to boot from USB drive, the ISOlinux bootloader came up as normal, I choose DEFAULT and off it went.... sure enough, it errored out at the same place as listed in the bug report ::
:: Waiting for boot device ...
Waiting 30 seconds for device /dev/archiso ...
ERROR: boot device didn't show up after 30 seconds ...
Falling back to interactive prompt
You can try to fix the problem manually, logout when you are finished
ramfs$
this time though, I issued the following 2 commands ::
ln -s /dev/sdb1 /dev/archiso
exit
from there, EVERYTHING worked as it should!
to recap: the solution for me was create a symbolic link pointing /dev/archiso => to my partition which held the archlinux netinstall (which is where I told Unetbootin to install it to)! done and done. I felt this needed to be posted here, as I could not find this solution after MANY google searches, archlinux wiki searches, forum searches, etc. honestly, I think it would be prudent to have this tidbit of information added to the Install from USB stick archwiki page as a side note to those that may run into this issue.
this is not the FIRST time I have run into this problem with a USB install of archlinux, but this is the FIRST time I found a fix! thanks to all the great posts I reference here, without this information I dont think I would have been able to install archlinux on my new alienware m11x laptop.
-peace-
PS: no amount of rootdelay=XX nor pmedia=usb nor usbdelay=XX would work in my above attempts either.

FAT16 here. Parted Magic sees my USB drive as sdd. I tried your way and surprise, surprise, it didn't work.
ln -sf /dev/sdd /dev/archiso
mount -t vfat /dev/archiso /bootmnt
mount : Invalid argument
I thought maybe you meant mount -f vfat /dev/archiso /bootmnt instead. I tried it too, it resulted in a kernel panic.
What else can I try besides installing from a IDE/SATA CD drive ? Because this issue is NOT solved. At least not for me. Wonder if "archlinux-2010.04.05-netinstall-i686.iso" from the here will solve it (really hope so).

Routers that can share iTunes library via attached USB HDD?

I am looking for a new router with a USB port for sharing a hard drive across the network. I am doing this because my desktop PC which currrently shares the HDD storage is dying, and I don't intend to replace it. I'll list what I have and what I want to do:
- 1 Windows 7 laptop, 1 New iPad, 2 iPhone 4, and 1 Sony BD Player with WiFi DLNA streaming
- 1 large hard drive in the dying dekstop PC that I'd like to move into a USB enclosure
- Would like to buy a new router to which I can attach the USB HDD
- Ideally, would like to place my iTunes library on this USB HDD and have the router be able to do iTunes sharing to all devices without needing to be connected to a computer
My questions are, is this possible? If so, which router(s) support this setup?
Thanks!

Hello,
The iTunes library is installed and added to my Mac with no issues. I just want to share the whole library with a Windows laptop.
As mentioned the 'Enable home sharing' does not seem to work. I am assuming it is the file format of the HDD which means the home sharing cannot be done on a Mac?
Thanks
Ian

USB HDD not mounting on 10.4.9 but does in 10.4

Posted this in Tiger forum too (I know, probably not really supposed to), but I thought I'd post it here too.
I know there's nothing wrong with the drive whatsoever, because it mounts on PCs, and it mounts when booted from both other hard drives on the system, on Mac OS 9.2.2 and Mac OS 10.4.0.
I know it used to mount on 10.4.9, too. I thought maybe when I installed a 4-port USB 2 card things would resolve, but they haven't.... so I expect it's a driver (extension) issue.
I deleted a bunch of extensions a while back that I was sure I didn't need... I suppose it's possible I deleted one vital for USB HDD support on the HDD using 10.4.9, only I don't know which it would be... things were self-explanatory in the days of OS 9, not so much with OS X, it would seem.
I didn't notice it until fairly recently since I'd been networking to the external HDD via another computer as the built-in 10BT was sadly faster than the USB 1.1 card I had installed prior.
Anyway.... since I assume this is an extensions problem (it says when I turn on the drive that a certain extension is missing, but I can't remember which), can anyone tell me what particular extension it is that enables USB Hard Drives?
By the way, USB flash drives mount and run at USB 2 speeds just fine.

"AppleXsanFilter.kext"
That is likely an extension for Storage Area Networks. If your Mac is complaining about it, it probably has unsatisfied external references in some of the Mass Storage Extensions. I don't know why you would need a lot of stuff in those folders, but they are tiny. You get no payback from throwing them out.
To fix those complaints, presuming the extension is located in the correct folder, you need to repair permissions (so that the System owns it) and delete the cache files named:
extensions.kextcache
extensions.mkext
which are pre-linked versions of most of the kext files. Then your Mac will recreate the cache files with the newly fixed-up kext added.

[SOLVED] Booting Arch off USB HDD fails - can't mount real root device

I've installed Arch on the internal HDD (sda) of my laptop, and I attempted to install a second copy of Arch on partition sdb3 of an external USB HDD. sdb3 is a primary partition that I had prepared beforehand with gparted and outfitted with the reiserfs filesystem. I skipped section 3.2 (manually prepare hard drives) of the Arch installer. There was no problem with section 3.3 (manually configure filesystems and mountpoints); I put all of / in sdb3. Installing packages and configuring the system also went without a hitch.
I wanted to boot this new install of Arch via the boot menu of GRUB that was installed in the MBR of sda with my primary install of Arch. On the new install, I first did go through section 7 (install bootloader), thinking I would want to install GRUB in the root sector of partition sdb3 (not in the MBR of sdb where the GRUB of MintKDE resides, a boot menu that I want to keep) but that failed, so I then picked "no bootloader to be installed". With that I exited the new install, since it appeared to have gone to completion.
I then copied the appropriate stanza in the /boot/grub/menu.lst of this new Arch install to the /boot/grub/menu.lst of my primary Arch install on the internal HDD of my laptop.
This stanza reads as follows:
# (3) Arch Linux on WDPP60 blue (sdb3)
title Arch Linux on WDPP60 blue (sdb3)
root (hd1,2)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/191cc027-43ce-443b-8846-f265d60555ec ro
initrd /boot/kernel26.img
However, I'm not able to boot the new Arch install when I pick this entry from the GRUB menu list. The new install starts booting, finds sda but not sdb and stops with the following errors, dropping me to a recovery shell:
Root device /dev/disk/by-uuid... doesn't exist. Attempting to create it.
ERROR: Unable to determine major/minor number of root device '/dev/disk/by-uuid...'
mounting /dev/disk/by-uuid... on /new_root failed: No such file ...
ERROR: Failed to mount the real root device.
Running "mount -t reiserfs /dev/sdb3 /new_root" at the ramfs prompt also fails.
I've tried a number of edits of the menu.lst stanza from the grub> command prompt, such as adding rootfstype=reiserfs, replacing root=/dev/disk/by-uuid..etc. with root=/dev/sdb3 (booting then fails with "/dev/sdb3 No such file"), using "initrd /boot/kernel26-fallback.img" etc., but booting always fails at the same stage with equivalent error messages.
I have no trouble booting half a dozen other Linux/BSD distros that reside on two different external USB HDD's by the same method, i.e. choosing an entry from the GRUB boot menu of my primary Arch install, after I placed the appropriate stanza in its /boot/grub/menu.lst.
How can I get this new Arch install to boot?
Last edited by RobF (2010-05-17 23:03:27)

Yes, this was in fact the solution. I stumbled upon it in this thread:
http://bbs.archlinux.org/viewtopic.php?id=65844
When one wants to boot from a USB mass storage device, the initrd needs to include the modules for accessing USB devices, and in Arch this is accomplished by adding "usb" to the HOOKS array. I simply reinstalled Arch to the USB HDD and in the system configuration step now edited /etc/mkinitcpio.conf by adding the "usb" item. Adding "rootdelay=10" and/or "rootfstype=reiserfs" to the kernel line in the appropriate stanza in Arch's /boot/grub/menu.lst wasn't necessary in this case. I left the stanza exactly as I posted it above.
Thanks for your input.

Copied files to USB HDD - now can't find them!

I had to reinstall my wife's macbook so I backed up all her files to a USB HDD formatted as MS-DOS (FAT) [according to disk utility]
I then reinstalled and tried to find the files which do not show up on the USB HDD (shoulda checked!)
I've seen posts alluding to having the drive formatted Journalised but they all refer to having done that FIRST.
Are my files history? Is there any way to get them back? Help!

Thanks so much for helping me with this.
I must admit, I didn't pay too much attention when importing this "test"
group of photos to LR4, therein lies my problem. Now that I look at the
import settings that were used:
1. Files were not added or copied, they were "moved" to a new location and
also renamed.
2. Files were renamed starting with "264" using my regular import template.
Listed below are the first 10 photos with their original LR3 and he
changed LR4 names.
1201_001 changed to 1201_264-2
1201_002 changed to 1201_265-2
1201_003 changed to 1201_266-2
1201_004 changed to 1201_267-2
1201_005-Edit-Edit changed to 1201_268-2
1201_005-Edit changed to 1201_269-2
1201_005-Edit changed to 1201_270-2
1201_005-Edit-Edit-2 changed to 1201_271-2
I have a back up of my images on an EHD from several days ago which has the
original file names, but this backup only has 203 of the 268 images I
imported yesterday and are renamed.
Thanks again,

Finder crashes when I try to open my external USB HDD

Hello all. I have been experiencing issues with my external USB HDD (WD Passport) and my Macbook Pro (Summer 2012) for some time. It looks that the HDD shows up on the desktop when I connect it but when I try to open the My Passport icon on the desktop Finder crashes. Finder works OK generally and I can see everything (even the Passport listed) but I cannot access the Passport HDD contents.
I have tried accessing it via terminal and managed to view the Passport contents ok (ls -ltr etc)
I have tried repairing the disk but the issue remains.
I have connected Passport to a Windows 7 PC and it works OK. I have even tried repairing it on a Windows PC but it has not helped.
Ejecting, rebooting etc does not solve the issue
Every time the issue occurs I see a PM Report Crash for Finder
11/24/13 5:46:21.004 PM ReportCrash[1374]: Saved crash report for Finder[1377] version 10.8.3 (10.8.3) to /Users/Panos/Library/Logs/DiagnosticReports/Finder_2013-11-24-174621_Panos-MacB ook-Pro.crash
Could you please suggest any solution to this problem??

Try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Airport Extreme + USB HDD = Time Capsule?

Hi!
(Sorry for my poor English, I hope it's possible to understand my problem/question).
I bought a MacBook in January 09. It's connected to the Internet via WLAN and a Fritz.Box (Wireless Router with built-in DSL Modem, unfortunately it uses the old slow LAN and WLAN protocol and a USB1-Port).
I want to backup my files with Time Machine via WLAN. I tried to connect a USB-Drive to my Fritz.Box but it was terribly slow (USB1...)
It's important, that the backups go automatically when I'm at home and connected to my WLAN.
Now I think of buying something that's more useful. I have three ideas and I'm not sure what to do...
1) Buying the Time Capsule. Pro: I think, it will work perfectly. I don't need to worry about a thing. Contra: It's terribly expensive. In Germany 1TB will cost about 600$. (Maybe I should buy the 500GB-Version and update it by myself to 1GB or 2GB).
2) Buying the Airport Extreme. Unfortunately I'm not sure if a Airport Extreme + USB-HDD is the same as the Time Capsule. Apple writes: "Time Machine in Mac OS X 10.5 Leopard can be used to back up to many kinds of Mac OS Extended-formatted drives, but you cannot choose AirPort Extreme's AirPort Disk as a Time Machine backup volume. " On the other hand some Users wrote that they managed to get their TM-Backup on a AE-HDD (but did this work via WLAN?). With the Airport Extreme it would be easy to manage a itunes-stream-server (the Airport Express is not too expensive). And the Airport Extreme isn't too expensive as well.
3) Using a Network-HDD. It would be not too good, since I had to use my slow WLAN-Connection and since this wouldn't be supported by Apple at all. On the other hand this would be the least expensive version.
What should I do? Is it possible to work with the Airport Extreme and an external USB-HDD via WLAN and without any problems (like mounting the drive manually each time I connect to my Network).
It would be much more fun, if everything ran automatically, when I got in reach of my Network...
Thanks in advance! Gerrit

A couple of pointers.
The hard drive must be specifically formatted in Mac OS Extended (Journaled) to work with the AirPort Extreme's USB port. Check the documentation that came with the drive to find out how it is formatted at the present time.....it is likely formatted to work with Windows, which is not compatible with the AirPort Extreme.
Unfortunately, even if the drive is formatted correctly, Apple does not officially support Time Machine backups to a drive at the USB port of the AirPort Extreme, so that will be the next hurdle to deal with.
Some users actually do seem to be able to make this work, but overall, it is not a reliable method to backup your data if it is important to you.

160 GB external USB HDD won't mount in 10.4.9; does in 10.4.0

I'm using a Beige G3 (though I don't think the model is the issue).
I know there's nothing wrong with the drive whatsoever, because it mounts on PCs, and it mounts when booted from both other hard drives on the system, on Mac OS 9.2.2 and Mac OS 10.4.0.

By the way, USB flash drives mount and run at USB 2 speeds just fine. Thanks.

It's an adaptec card, but that's actually not the issue; it stopped working on the old USB card where it'd worked just fine before, whilst still working when I booted into 10.4.0.
Once upon a time it was working fine on both 10.4.9 and 10.4.0.
It now says "AppleXsanFilter.kext" was installed improperly and cannot be used" when I start up the drive. It knows it's there, it just can't access it. It then says "device was improperly removed" when I shut off the HDD.

Floppy drive install to portable USB HDD & Floppy to boot from

title pretty much says it all. I have a resonably old computer that cant boot off of usb. and i want to install it to a usb hdd. I dont have a cd drive so i will have to use the floppy network install (i did this before). This is the only distro that I know of that has a floppy install. i have searched but the wiki search brings up like 500 results that are irrelevant. so in short this is what i need:
a floppy to be able to boot from a usb hdd
a guide that can show me how to install from a network install floppy setup to a usb hdd
if i remember correctly, the floppy network install is much much different than the cd install.

dont know if it will be able to install to usb but
image can be found here

may be you can install arch to usb via a different pc move usb to desired machine boot floppy.img chroot run grub/lilo onto another floppy disk

[Solved]Boot from USB HDD - Root device doesn't exist. Major/minor

My problem is that the kernel seems (or starts) to load, but then I get an error:
Root device 'UUID=1234 . . .' doesn't exist.
Attempting to create it.
ERROR: Unable to determine major/minor number of root device "UUID=1234 . . .'
You are being dropped into recovery shell
I found a few links on the web and in the forums, but nothing that really solved it for me. The solved ones usually downgraded the kernel. I haven't done that yet. I thought I'd try here first.
I have a 320GB USB HDD that I have been using to experiment with different linux distros. I have a few working successfully (OpenSUSE,Mint,Ubuntu,Debian,Fedora,etc). I'm very new at this but have been reading a lot and putting a lot of time into it. I have legacy grub loaded on the MBR and use the menu.lst on my openSUSE partition to boot everything. Because the partitions for some of the distros are so far into the disk I needed to create directories on openSUSE's /boot directory to contain the kernel and initrramfs files (like /boot/fedora). This seems to work for the other distros. I did the same thing for Arch.
So when I installed Arch I haven't used the bootloader section of the installation.
I'm using the 2011.08.09-netinstall-i686.iso Live CD.
I tried a few things including:
1. changing the HOOKS in /etc/mkinitcpio.conf
a. adding usb to the "HOOKS"
b. removing and adding autodetect
c. adding and removing "sata_sil" (although I'm not even sure if my device uses it)
2. changing the kernel line:
a. from using "UUID=" to (hd0,1) to sdb1.
b. added rootdelay=8
3. repartition all of my arch partitions using cfdisk from my Live CD and reinstall. I used gparted on OpenSUSE to do it the first time.
This may be connected. When I fdisk -l from the Arch Live CD I get extra data and an error for each of my arch partitions (and only my arch partitions):
Disk does't contain a valid partition table
When I fdisk -l from OpenSUSE I don't get the data paragraphs or errors about the arch partitions?
Here is my /etc/fstab:

I'm IN! Thanks everyone for your suggestions!
The arch system didn't like the identifier I was using for the root partition. By looking at the /dev/disk/by-id while the arch system was running, I could see what the system wanted me to call the partition. So after the system error'd-out and I was in the recovery shell at the [ramfs /] prompt:
# ls -lF /dev/disk/by-id > by-id.txt
# vi by-id.txt
I could have used any of the identifiers listed in the by-id (there were 3), by-uuid(1), by-label(1) or by path(1). I tried them all. I had to write these down by hand because it is a ram filesystem.
The article that finally got me there is:
https://wiki.archlinux.org/index.php/Pe … ice_naming
Anyway my openSUSE grub menu.lst ended up like this:
####arch on sda10 - legacy grub
title ARCH
root (hd0,1)
kernel /boot/arch/vmlinuz-linux root=/dev/disk/by-uuid/510bb601-13c1-46ec-87c0-a800dd2efb8b ro rootdelay=8 rootfstype=ext4
initrd /boot/arch/initramfs-linux.img
savedefault
boot
It's easy once you: 1. beat your head against the wall
2. read further
3. repeat 1 and 2

Lenovo C255 - USB Drive and USB HDD is not recognized

Hi
I am trying to attach SSD (Kingston SSDnow 300 - 60gb) drive to PC via bridge SATA-USB to USB 3 port, so i have "USB to ATA/ATAPI Bridge" stuff at installed devices and no HDD disks appeared at MyComputer . Still i have 2 disks at Device manager - my native HDD and this USB Drive.
The problem is that BIOS doesn't see any USB HDD. Excluded from the bootable device : USB HDD USB CDROM.
So how i can solve this issue ?

Hi
I will try to help you buddy.
> When it is started is says "Insert system disk in drive. Press any key when ready
This message appeared on my notebook after the HDD has died.
I had to replace the HDD and to install the OS again.
I assume its the same problem with your notebook. The HDD is not present or not recognized and you have to install a compatible HDD to get the OS running.
I have googled a little bit and found out that this notebook was delivered with the 10GB Toshiba MK1016GAP HDD. It supports the ATA-2/ATA-3/ATA-4/ATA-5 interface.
Please note that many BIOS have an HDD size limitation. This means that not all HDD sizes are supported! I presume a 20GB should be compatible but this is only my own opinion
> How can I change my BIOS so that the HDD is recognized?
The BIOS cannot be changed apart from the update (check Toshiba driver page -> Archive -> Satellite Archive).
But vary important is that you will use a compatible HDD.
> Can anybody help me with the recovery CD?
Dont know if you will be able to order this CD from the authorized service provider in your country because the notebook is really an oldie. But you should ask the guys.
What you could is to install the OS from the Microsoft CD and then could install some necessary drivers.
Greetings

Can't access my Seagate USB HDD on my Airport Extreme

I can not access my 1TB Seagate Freeagent USB Harddrive over the working AEBS network. Hoping to be able to share and stream files to all remote laptops in the house. I have the HD connected to the AEBS and the AEBS client identifies the HD under Disks by name with the correct information. It's set for file sharing and Share Over the WAN. The workgroup is set to WORKGROUP to match my laptop and I've also gone into Windows and dissabled Windows Search per other suggestions on another discussion.
All that said and done, I still can not see or access the HD via my Win7 laptop. I see there are tons of disscussions on this issue and seams many are frustrated because the meager AEBS instructions that come with the unit simply say "Connect the hard disk to the AirPort Extreme USB port using a USB cable. Open AirPort extreme utility, select your base station, and then click Continue. Follow the onscreen instructions to create a new network, if you have not already set up your network." which I already have. Do I need to do this again? Are there any other settings I can do in my Win7 system or in the AEBS system to be able to access my ext HD? I really don't want to format the HD as some users are talking about.
Any thoughts or suggestions woudl be helpful. This was a main selling point for me deciding to buy this router.
Thank you much.

Update...I've also formated my USB HDD to exFAT and still can not access it via the network. It is still completely visable in the AEBS client software. MAC OS was not an option for formating. I thought that exFAT would work since its the newer type of FAT32. Is there a program I can download to format the drive to a MAC OS format and then be able to acces the drive on my four Win7 PC's?
I'm at my wits end with this AEBS and am ready to pull the plug and take it back for an exchange to a Cisco Linux 4200. Please let me know if there is hope for a fix.

Cant see usb HDD connected to AE(n)

I accidentally unplugged power from my HDD while it was connected to my AE(n), and now I cant get the HDD to be recognized by the AE, or when connected directly to a computer with usb. Thankfully the HDD has firewire ports also, so i am able to access the drive that way. Any suggestions how to get this HDD to be recognized via usb again? Thanks in advance!
Mac OS X (10.4.9)

Yes, it is using a USB chip that the TC cannot talk to without a hub. This is due to lack of drivers I think.
I posted a thread to which I have no answers.. but if you would like to fill in the details I think it will explain what is happening.
