'Cannot open mirrored root device' -- after dd and h/w swap

Hi All,
i needed to clone the server (netra440, sol10)so i took a sector copy (dd) of two mirrored hard disks
and tried to start from them on another netra440 server , i've got an error listed below,
is there any way to bring this mirror to life if given that original server is unavailable anymore?
thanks for any hint

System can be brought up in this way; however do you have any idea if the root disk has been encapsulated by VxVM before this panic during the reboot?
I`ve encapsulated the root & its mirror under veritas volume manager and rebooted the machine and landed upon

If I upgrade to linux 3.6 with this line:
HOOKS="base udev autodetect pata scsi sata mdadm filesystems usbinput fsck"
in /etc/mkinitcpio.conf, the system is able to boot.
if I upfate to linux 3.6 with this line:
HOOKS="base udev autodetect pata scsi sata mdadm_udev filesystems usbinput fsck"
in /etc/mkinitcpio.conf the system is not able to boot.
I gathered that the mdadm_udev hook was preferred but it seems to cause problems in this case.
After I successfully upgrade (having "mdadm" in /mkinitcpio.conf) I can change "mdadm" to "mdadm_udev" and
the system will still boot fine.
Does somebody know what gives?

I have photoshop CC. I cannot open two files such as Tiffs and view them side by side. When I open the second file it overrides the first. Do I need to do something with preferences?

What happens when you try to use the clone stamp tool?
It should work with the images side by side.
You can setup photoshop cc to be like photoshop cs2 was on your other mac, by going to Photoshop>Preferences>Interface and unchecking
Open Documents as Tabs and Enable Floating Document Window Docking
And also going to Window and unchecking Application Frame

I think the last update did not work, and now I cannot open jpeg attachments with windows picture and fax viewer, it is not listed in the tools/options drop dow

I don't believe the last Thunderbird update worked, there was a very fast error message. But since then I cannot open jpeg attachments in Windows Picture and Fax Viewer. If I go to Tools, then options, the jpeg line is grayed out, and the drop down menu does not show Windows Picture and Fax Viewer. The windows picture and fax viewer still works on my computer, but not for opening attachments.

I did as you said - deleted the entry for jpeg, but when I tried to open one there is not an option for Picture and Fax Viewer in the drop down, and it can't be found by browsing. It's just not there anywhere even though I can see pics in it except in email attachments.

Cannot open CS6, it craves JBX-plugin, and my Mac doesn't recognize the file so I can't download

I wonder why CS6 is not complete when downloaded? Why should I have to download JBX? If needed it should be a part of Indesign. My Mac doesn't have a name of a file to open and download, so now I simply don't have CS6 and can't convert my book to Kindle for sales on Amazon.
Terribly disappointed!

I am attaching the Kindle Plugin also.

I have photoshop cs5 installed on desktop...got new Canon rebel T5i camera...cannot open RAW images...updated and installed plug-in...still not working...help please.

In any event, that camera was first supported by ACR version 7.4 which needs at least CS6 to run. Naturally, all later versions support it too.
Your choice is either to upgrade your Photoshop, or to look for, download, install, launch and run the free, stand-alone Adobe DNG Converter 8.6 on each folder containing your raw Canon files to convert them first to raw DNGs that you can open in CS5.
In no case does an Adobe application belong "on your desktop". The default install location should always be respected and left alone.

[SOLVED] cannot find root device after pacman -Syu

Today I had a problem after pacman -Syu. Of course, my problem stemmed from not paying attention to the following (from https://bbs.archlinux.org/viewtopic.php?id=57205):
<b>Read pacman's output while upgrading.</b>
I could no longer boot. I received a message "cannot find root device" or something similar indicating a device with the appropriate UUID had not been found and I was being dropped into a recovery shell, then, when I typed exit, an emergency shell, followed shortly by a freeze.
After some investigation it appeared my initramfs was broken/non-existent/something after the install. I booted into a live CD and found that updating pacman again, and mkinitcpio -p linux both displayed the following error: "Failed to create temporary working directory in /tmp". Long story short: mktemp was segfaulting. This should be extremely easy to check if you're having a similar problem. I replaced it with the version on the live CD and ran the pacman update again. Success. If you do this, you may need to make sure your live cd architecture and installed kernel architecture are the same.
I'm not sure of the etiquette here, so I'm posting this in case someone else has the same problem I did; and benefits from a similar solution. I have checked the etiquette post and I don't think it's clear whether it's kosher to post things that don't actually require a solution. However, if I have misinterpreted the rules/etiquette and/or this type of post is considered extraneous please remove it.

You have to use lvm first. As all those vg*, lv*, and pv* commands are actually links to the lvm command, you should have to do something like "lvm vgscan" instead of just "vgscan".
Edit: oh and at that point in the boot process, you are actually in the initramfs still (ash to be specific).
Edit2: I was having issues with a USB keyboard and a new machine (actually just a new bios), and found out that because of windows 8's requriement for a fast POST, the default is to turn off the scanning for usb devices. Though this was for UEFI, and I am not sure if the same would apply for a bios booting machine...

BIOS-GPT grub cannot find the root device in LVM setup

Greetings Arch Linux Community,
Recently I started my journey of installing Arch Linux on my VMware Workstation.
I successfully installed the non-LVM instance not long before I noticed the advantages of LVM, then I just started a new Arch Linux setup with LVM.
However, after following the Beginners' Guide and LVM Guide carefully, I ran into a problem on boot that I cannot solve by myself due to my poor knowledge on boot/grub.
Here is the error message:
ERROR: device '4b28d500-8ed3-4fe5-ad26-97fbb01f979b' not found. Skipping fsck
ERROR: Unable to find root device '4b28d500-8ed3-4fe5-ad26-97fbb01f979b'
The error message itself is pretty clear; saying that the root device specified by my grub.cfg cannot be found and thus cannot be loaded.
However, I'm 100% sure that the device is actually there and just for some reason grub cannot see it.
Below please see the info from lsblk, pvdisplay, vgdisplay, lvdisplay, and some related info from fstab, grub.cfg and mkinitcpio.conf:

Sorry, im newbie ( dont take my advice seriously ), but im very curious about his, because once i couldnt install grub as well so i went for syslinux instead , and i know i will have one more fresh install of arch to do, so im curious
Hi Efka, I used grub-install and specified "/dev/sda" for argument. What I understand is that the sda is the identifier for the hard disk where all the sdaX reside. And if you look into the output of my lsblk, you will see that there is one partition sda1 that has no filetype, label and UUID on display; that is actually the bios boot partition where, as I understand, the grub code embeds itself.
We can have different partition scheme to deploy and having a separate partition for /boot is just my personal preference ans it should work as well.

Cannot open Language settings from Tile view, and unable to install Language packs from WSUS.

Hi all,
I have a bunch of Windows 2012 R2 servers that have been deployed from a syspreped image where the language has been defaulted to "en-GB", rather than the default "en-US".
I also have a WSUS 3 server running on a Windows 2008r2 machine. This tells me that a number of language packs are required by these 2102r2 machine, namely:
KB2839636 - English (United Kingdom) Language Pack
KB2839636 - English (United States) Language Pack
KB3012997 - English (United Kingdom) Language Pack
KB3012997 - English (United States) Language Pack
These have been approved to be installed on the 2012r2 machine, however, running Window Update on the machines shows nothing. Opening the Control panel, then navigating to "Add Language", then "options", shows no additional updates.
The I tried to search and run the languages control panel directly from the Windows Tile view by simply typing "language" and clicking the 'Language' option in the search results, but then get the following error dialogue box:
[Window Title]
C:\Users\Administrator\AppData\Local\Packages\windows.immersivecontrolpanel_cw5n1h2txyewy\LocalState\Indexed\Settings\en-GB\Classic_{bf782cc9-5a52-4a17-806c-2a894ffeeac5}.settingcontent-ms
[Content]
Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.
The issue I have here is that I am logged on with the Domain Admin profile, but the path above refers to the local admin profile - however the file listed has full permissions for all 'Administrators'.
So I have two questions:
How should the Language pack updates get installed from WSUS?
How do I fix the problem with trying to open the Language option direct from the tile search view?
Many thanks
Chris

Might try these ones.

Cannot open file from Bridge after saving in Photoshop CS3

I was working on three images in Photoshop CS3, when I went to open them from Bridge for review, two of three files were reduced to tiny white squares with a dogear in the top right corner, a little blue bounding box containing three tinier red green and blue somethings so small I couldn't even see what they were with my jewellery spec.
Nothing happened when I clicked on them, no error message, nothing. I managed to get one of them in 'reveal' - which opened up a larger blue bounded box with the red button containing a cross with the message 'cannot open as not right kind of file'.
What to do please? I don't want to spend hours on an image and hope it will open afterwards. Thankyou.

Thankyou for taking the time to respond. I did notice that I'd forgotten to place a . after the file name and before the extension - ie soiphotopsd, instead of soiphoto.psd, and renamed them and the opened as psds. I would have thought that Photohop CS3 with all it's bells and whistles could have provided a helpful popup/error message to this effect when saving images though!
I still have an old file I haven't been able to open, the icon of which is simply a small blue and white box with the letters pmg on the bottom. I tried to rename the file same as, but nothing seemed to work so far. Will just keep plugin away - forgive the pun.
Thanks again.

[SOLVED] Can't find LVM root device after pacman -Syu

Hey, can anyone give me a hand here? I haven't updated in about a month, but the last time I did was definitely after the changes-to-lvm post in the news (I know that because it's what got me on the last update )
I noted just before the update that cat /proc/1/comm displayed "init", which surprised me. Maybe I'd installed systemd but not configured it?
Anyway now I'm getting:
Waiting 10 seconds for device /dev/mapper/belle-root …
ERROR: Unable to find root device '/dev/mapper/belle-root'
You are being dropped to a recovery shell.
I've chrooted from a SUSE CD I had lying around and followed the "changes to LVM" instructions again in case I'd missed something, but nothing is changing.
Can anyone help me out? Thanks.

You have to use lvm first. As all those vg*, lv*, and pv* commands are actually links to the lvm command, you should have to do something like "lvm vgscan" instead of just "vgscan".
Edit: oh and at that point in the boot process, you are actually in the initramfs still (ash to be specific).
Edit2: I was having issues with a USB keyboard and a new machine (actually just a new bios), and found out that because of windows 8's requriement for a fast POST, the default is to turn off the scanning for usb devices. Though this was for UEFI, and I am not sure if the same would apply for a bios booting machine...

Cannot open QB 2007 file after installing R7 upgrade

I installed the Quickbooks Pro 2007 "upgrade" and then tried to open my old Quickbooks Pro 2007 for Mac company file.
1.) It asks me if I want to Upgrade the file (no choice)
2.) Then it simultaneously says "Working" and gives me a warning about the file not being able to be renamed and that I have to rename it and save it in the QB folder.
3.) Then - whatever name I give it - it says it could not create the upgraded file.
4.) It also says that it could not open the existing file.
I'm not sure what to do - the file is only 4.7MB and I've tried every combination to get it to open.
Is there some trick? Nothing about this on the Intuit Forum. Nothing on Google either.
Help would be greatly appreciated as I cannot open my business file!

I guess what is happening is that I originally installed quickbooks and the company file on my macMini and I suspect that it is not opening it on my iMac because of a sharing violation.
I did unlock both the application and the files but they still won't open.
Any suggestions would be appreciated.

Cannot open Lightroom on iMac after download of OS X Yosemite

After downloading Yosemite on iMac I cannot open Lightroom files. I am getting the message "The Lightroom catalog cannot be used because the parent folder “/” does not allow files to be created within it."
Can somebody help me please.

Here are some start up commands you might like to try Startup key combinations for Intel-based Macs - Apple Support
Personally I would try in Recovery mode...OS X: About OS X Recovery - Apple Support
