Vhd and Vhdx corrupted

Hello, I have two servers Hyper-V 2012R2 connected to a new SAN (powervaul NX3200). I started to move my virtualmachines to
the new SAN. I have now ten virtual machines on the SAN (about 40% of my virutelles machines) others arelocally on the servers. The purpose is to transfer everything to the SAN. But for some time I had problems with my virtualmachines on the SAN. I have two
machines that have disappeared. The folder and the vhdx file are no longer there. I havethree machines corrupt. The vhdx files are 0 KB. I'm connected to the iSCSI SAN. On each of my two servers, I have a NICdedicated to the SAN. They are on a different network.
My network internet 192.168.10.xx and the network of SAN192.168.5.xx Yesterday I have this message on my iSCSI drives: Offline Scan and Repair Needed. I made the repair. So, i need some help.

Are the Hyper-V hosts stand alone hosts? Are the Hyper-V hosts pointing to the same storage locations for the VMs? If you answered 'yes' to both those questions, you have configured an environment that is guaranteed to corrupt any data on the
volumes being pointed to. The only way to share storage locations between multiple hosts is to configure some sort of sharing mechanism. Within Windows, this is Failover Clustering.

VHD and VHDX won't Compact

I also have the same problem.
If I compact a VHD or VHDX the compact runs for one second and ends, and the VM's remain uncompacted.
I am using REFS format on the drive, and the VM's are Windows 7 x86, if that makes any difference.
I have disabled System Restore in VM's, as that was a known problem with 2008 R2.
Can this be reported as a bug in Server 2012 RC.

I was having the same problem (minus using ReRF, I am just using NTFS.) I think I finally discovered the "real" issue for me, and the solution. My VHD and VHDX file (tried both ways) has two partitions in it - being a virtual machine for Windows 7 that we
use to create images, it wound up having the small 'system reserved' partition, plus the normal OS partition.
I think what was happening is that only the first partition was being looked at (the small one) and so the optimization, etc, was never happening on the large one. Which would explain the way it came back in just one second (less, really.)
The way I found to get around this was to use a new feature in 2012 - I right-clicked on the VHDX and chose "Mount." This attached *two* drives (can't seem to choose the drive letters.) Then in a "My Computer" window, used the ribbon option "Drive Tools
-> Manage" and chose the "Optimize" tool. Ran the optimization on both of the newly attached drives, closed that out, and then ejected one of the drives (both of them detached when I did.)
Finally, when I ran the "compact" in HyperV Manager, it took a bit longer and actually decreased the size of the VHDX file (in my case, from 31GB to 20GB.)
Hope this helps someone!

Using DFS-R to replicate VHD and VHDX Files

Hello -
I am trying to find a solution to replicate VHD files and VHDX files between two data centers. I'm deploying the solution using Windows Server 2012.
The VHD files are not virtual machines, they are simply storage areas (one for each user) that contain user documents and other files.
The users will potentially log on to terminal servers in two locations and I'd like the VHD files to be accessible from both locations. The VHD files will mount during the logon sequence into a mount point within the users profile (or some other accessible
area within the file system). This is a bit like user profile disks, but more user data disks.
Has anyone attempted the replication of VHD files before using DFS-R, and are there any things I should be aware of?
Will DFS-R support delta replication of VHDs? If a user has a 500 MB presentation, within the VHD file, and changes a single line of text, I'd prefer for only the changed blocks to synchronize.
I don't believe DFS-R supports replicating open files, so I understand that the data won't be in sync until the VHD file us unmounted, but thats okay.
Cheers, I'd welcome any feedback.

If you don't own a pretty fat pipe between the data centres (and it comes free of charge) that's not the best idea. For a reason: DFS-R does use compression only paired with per-file changed block tracker no deduplication see...
http://technet.microsoft.com/en-us/library/cc771058.aspx
...so at the end of the day you'll replicate TONS of non-required information. What you really need to do: deploy a third-party replication solution layered up and working on top of the volume(s) where your VHD/VHDX files are stored.
Will DFS-R work to replicate VHD/VHDX? YES
Is DFS-R optimal for VHD/VHDX replication scenario? NO
Hope this helped :)

Domain controller VMs using dynamic VHDx corrupt after power failure

Over the past couple of months I have experienced 4 dead 2008 R2 SP1 domain controllers after power failure on Hyper-V 2012 hosts. The domain controller VMs will start after power failure and have varying degrees of file system corruption. In each instance
the corruption has rendered the domain controller unusable. The problem has not occurred with every power failure, but in testing the failure rate has been over 10%.
The Hyper-v 2012 hosts are as follows:
Dell PowerEdge r720 with flash backed write cache on Raid controller
Dell PowerEdge T710 with battery backed write cache on Raid controller
Dell PowerEdge T310 with a single SATA hard drive and write cache disabled
Generic system with a single SATA hard drive and write cache disabled
The VM configuration experiencing corruption is as follows:
Each VM was created from a base 2008 R2 SP1 syspreped VHDx image template file (40 Gigs)
The image template was originally created as a VHD and was then converted to a VHDx
The VHDx file has 512k sectors instead of the native 512e of VHDx files (a result of VHD - VHDx conversion)
Each VM was assigned 1024 Meg RAM and 1 virtual processor
The domain controllers were created by promoting the base 2008 r2 install to a DC after base image deployment
Only one corrupt VM was not running the 2012 integration components. The rest were running current 2012 integration components
I have done extensive testing on this issue and the problem for me seems to revolve around the VHDx file format. I have managed numerous Hyper-v installations since the original 2008 server version was released and I have never seen corruption like this
until 2012 and VHDx.
For the past few days I have been testing fixed sized VHD VMs on a 2012 host and I have not been able to reproduce the data corruption issue. I seem to only be able to reproduce the problem when using dynamic VHDx files. I have not done any testing on 2012
hosts with fixed size VHDx files or dynamic VHD files.
It would be great to hear from anybody else experiencing similar issues so that we can compare notes and hopefully get to the bottom of this problem.

To be honest I was excited to see this fix released, but there are two problems.
1. The hotfix causes BSOD if you have VLANs with a teamed NIC configuration. I found this out the hard way on a production system. How in the world did this thing get through testing and into automatic updates?
2. The hotfix does not seem to resolve the issue in my test environment.
I opened up a case with support and they informed me that they would not provide support for this issue and that I had to open a case with premier support. Premier support informed me that I cannot open a case with them unless I sign a $50,000 per year service
contract. Is there anywhere to get support on this issue?

I have an iMac mid 2010. After Disk utilities said the drive was corrupt, I ran the hardware test (extended) 3 times. No problems. I than ran Disk utility again and got 2 messages in red…keys out of order, and ……Volume corrupt, can't be repaired.
I tried to do a system install, but message said…disk can't be changed. Will a complete erase and install fix this ?
Everything is backed-up.

There's hardware and software.
Your drive could physically be in good condition but something has caused the file structure to be messed up (it just happens sometimes). The directory that keep track of files is corrupt. Disk Utility can help determine if that is the issue. In some cases it can repair the problem but it cannot do it to a drive that is being used to boot the system while you are doing that. You have to boot from another drive. Some things DU cannot repair and you need to try a stronger utility such as Diskwarrior.
A failing hard drive (one with mechanical issues) can be a cause of file structure issues but this is by no means always the case. Apart from looking at the SMART diagnosis feature of Disk Utility (and smart isn't totally reliable) there often isn't a way to tell if a drive is failing until it suddenly happens, which is why you need to maintain backups.
In your situation it does sound serious and not just minor directory corruption. You can try erasing (formatting) the drive, You may need to do this if it is really corrupt, in which case there could be underlying physical issues. I use old technology but if you have the patience you can try erasing the drive with the security option of writing zeros once (don't do more unless you are going on a 3 week vacation). This makes the drive not simply assume everything is okay by forcing it try every part of the drive by writing data. If something is gong wrong you may find it marks a lot of bad sectors, or flat out refuses to format. Then you know you need a new drive.

My Adobe Illustrator is CS6 and it corrupts the file if I save it using accents

My Adobe Illustrator is CS6 and it corrupts the file if I save it using accents. How do I fix this?
I mean, if I save a file called "crachá" I'm using an accent on "a" so it showed as "á" but if I do this Illustrator says the following error:
"The file may be read-only, or another user may have it open. Please save the document with a different name or in a different foulder"
and when I try to open it says:
"The file "Crachá.ai" is in an unknown format and cannot be opened."
So, my solution is to create a new file and call it "Cracha", without the accent. But it never happened before. How can I fix this legitimately?
Thanks.

As for the resolution problem: upsampling an image doesn't improve its quality, because there's simply not enough information there.
As for the warning you get: it's most likely caused by RGB color mode or by placed RGB content that interacts with other content in the file (e.g. because you applied transparency)
In English it's this one:
As far as I see it there's no alternative to learning the basics of printing, color management and transparency. This is nothing that can be done by some forum posts.
Printing:
http://rufus.deuchler.net/2011/06/adobe-publishes-a-new-creative-suite-555-printing-guide. html
You need to understand what's happening on conversion of RGB to CMYK color space, which will happen when printing to offset presses. When you print on office printers, something else happens and all kinds of color may come out, because these machines sometimes do their own color correction and everything depends on how you set up the machine.
Provided you check the PDF in Acrobat: you need to set up color management there as well. This might lead to the differences (greenish) you're seeing.
Find a good book on color management and read the manual:
Creative Suite * Understanding color management (there's more about the subject)
As for transparency:
http://partners.adobe.com/public/asn/en/print_resource_center/Transparency-DesignGuide.pdf
http://partners.adobe.com/public/asn/en/print_resource_center/TXPGuide.pdf
Before sending files to a print service provider you need to get information on how they need the file. Most providers won't accept PDFs generated with "No color conversion". Or they won't guarantee for the output.
What you see on your monitor won't necessarily match the printed result unless your system is correctly calibrated and color management set up. And even then there might be differences.
Can't you contact this former colleague, pay him an amount of money and let him teach you the tools of the trade?

Final Cut Crashed and then corrupted the file. So Final cut wouldn't open up. I tried reloading the backup, trashing the prefs file, systematically going through the 3 previous versions and opening them by themselves one by one to no avail.

Final Cut Crashed and then corrupted the file. So Final cut wouldn't open up. I tried reloading the backup, trashing the prefs file, systematically going through the 3 previous versions and opening them by themselves one by one. I found Final Cut now loads but each of the backups and files in the previous 3 versions won't load. I've worked on the project for 3 weeks. Im suprised the backup files won't load either!?! I've only rendered 1 low res version. I am thinking I will have to rebuild the project in Final Cut 7. That is simply too risky to have all my back ups not load up!!

I'm a little confused by this?
Final cut now opens if launch older projects. But if I actually click on the project it crashes. Im not sure what you mean by events? I've moved them from the events folder.
but when I open up and of the projects the FInal Cut opens but then wont load the project even with no events in the FInal Cut Events folder.

I updated iTunes on my Dell Inspiron lap top and it corrupted my iTunes. I uninstalled all of the newly installed files. I also uninstalled iTunes. Now whenever I try to install iTunes, I get a message that says, "An Apple Application support is required to run iTunes on this computer. Please uninstall iTunes, then install iTunes again."
Tried it 2 times and no luck. Any advice for me?
Maureen

I get a message that says, "An Apple Application support is required to run iTunes on this computer. Please uninstall iTunes, then install iTunes again."
With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

My laptop and external hard drive both failed and got corrupter.

My laptop and external hard drive both failed and got corrupter. I've lost my quick time pro 7 and all my music, I still have my Ipod with the music on, How can I get it back on to Itunes and quick time pro back on to my PC? Many thanks.

Since your current editing workflow is based around Virtual Copies there are no actual files containing the edit data. Therefore, you'll need to use the 'Import from another catalog' option ( see File menu).

Thanks!

hi
I think you won't see any summary on this, only when corruption is found.
There is also one related setting that can be incorporated here - see example:
Example 2-25 Specifying Corruption Tolerance for Datafile Backups
This example assumes a database that contains 5 datafiles. It uses the SET MAXCORRUPT command to indicate than no more than 1 corruption should be tolerated in each datafile. Because the CHECK LOGICAL option is specified on the BACKUP command, RMAN checks for both physical and logical corruption.
RUN
+{+
SET MAXCORRUPT FOR DATAFILE 1,2,3,4,5 TO 1;
BACKUP CHECK LOGICAL
DATABASE;
+}+
use this to see clear output:
-- Check for physical corruption of all database files.
     VALIDATE DATABASE;
-- Check for physical and logical corruption of a tablespace.
     VALIDATE CHECK LOGICAL TABLESPACE USERS;
eg.

I try to drag a photo folder into lightroom 4 on my MAC, lightroom fails to open and a 'Corrupt Catalog Detected' screen pops up. Clicking on 'repair catalog' does not work either. Any suggestions?

I'll have to get a better instructor on deleting the preferences since when I've doen it in the past nothing is there when I open LR the catalog is gone. I assumed that was what was supposed to happen so I start importing all over again. But that is a different issue...
The problem has been happening since at least the beta of 3 came out and I saw other posts back then saying they had similar issues but I assume it was a beta thing... But since the full version came out and through each incremental change I haven't seen an improvement. If anything it has gotten a little worse with time.
I have to try to be careful to not be in a hurry and start clicking around in the catalog as it seems fragile until it has cataloged all the photos in the library. When starting you will see the numbers populate the folders very slowly and I try not to click on a folder that hasn't had the number of photos pop up yet. Also draging the slider down to see more of the cataloge can have the same affect and crash the system.
I wish I had more to go on.. I believe it may be a resources issue but as I went from 3-4 Gig I thought it would get better. I don't have big programs running but did have outlook and word running in the background along with firefox and chrome.
And yes it only happens on this HP desktop (it's 2+ yrs old) and may be showing it's age a bit. My laptop which has less resources doesn't have the issue.. I have them sharing the catalog. (not at the same time) just when I'm working in other places in the house.

My iPod Classic syncs some music on and then corrupts and wipes... Help?

I decided to restore my iPod Classic 160GB because it was running a little slow.
I have since on numerous times over the past few weeks tried to restore all my music back onto the device but I've came up with the same problem everytime.
Everytime I sync it, it gets to around 10% of my music library onto it and then corrupts and wipes itself and demands a restore.
I've tried everything with the files. I have put them into sepreate smaller playlists, I've ticked and unticked them all and I've restored the library itself but not to any avail.
Can anyone help me?

The iPod hard drive has bad sectors, a replacement hard drive will resolve your issue.

Merge .vhd and .avhd files

Is there anyway to merge a disk's .vhd and it's .avhd metadata?
It's hard to make a differencing disk when the VM i'm making the base from never seem to update it's (empty) .vhd file.

Please note that this is not a supported method...it is kind of a hack, but it works....
I think it is also worth noting that I am using Hyper-V Manager, and not SCVMM, and I did not have a branched snapshot scenario. In other words, I never reverted back to a snapshot and then took later snapshots, thus "branching" the differencing files...
With that said...I don't think you have a lost cause if you are out of disk space...
The configuration for each VM is an .XML file...If you delete that .XML file, Virtual Machine Manager loses all knowledge of it (Please note a status of "Saved" complicates this more, but not worth going into now since you mentioned that you could shut down the VMs) Please also note that you will be recreating this VM, so you will need the information regarding number of Processors, and amount of memory, and the like. I was also told that this could cause you to need to activate the license again, but I did not have this problem.
In order to delete the .XML file for the VM, the Virtual Machine Manager Service has to be stopped. Before doing that, all VMs should be shut down gracefully if possible.
Here are the steps:
1. Shut down all VMs gracefully
2. Stop the service using services.msc, or stop the service using the Server Manager
3. Let any merge jobs complete that can
4. Delete (or rename for those of you carefull folks) the .xml file for the VM in question
5. Restart the Virtual Machine Management services...Your guest will not be listed.
6. Find the GUID for the VM in question...and delete the .xml configuration file.
7. Find all of the .avhd files for the machine
8. Move as many .avhd files as you need off to another drive to free up some room, but leave the last 2(very important to start with the last .avhd files and work your way backwards)
9. Change the extension on the LAST .avhd file to .vhd
10. In Hyper-V manager, chose edit disk
11. Browse for the renamed file
12. Chose to Merge the file (It will automatically look for the parent of the .avhd file...this information is included in the child file itself)...the merge will merge all information from the Child into the Parent, and THEN delete the child (this is where your space problem came in, btw)
13. Move the parent of that file (the next oldest .avhd file) back to its ORIGINAL location (very important to put it back where it was)
14. Repeat as needed
Always rename the newest Child to have a .vhd extention, because the "Edit Disk" wizard only sees .vhd files, and alway merge into the Parent, and not to a new file.
This way, you have the room you need to merge the files, and eventually, you will arrive at the original .vhd file, and have only one virtual hard drive.
After all of this, just re-create the Virtual Machine, and use the combined .vhd file in the Wizard...
