Urgent ! VM not booting after LUN alignment using PAT Tool

Hi Experts,

I would like to get some help very urgently.

I did a LUN Alignment on 3 windows 2003 servers :( "Production" using PAT tool from PARAGON. After the alignment the VM does not boot to windows after the POST and BIOS i get this error

"A disk read error occurred Press Ctrl+Alt+Del to restart". Im not able to go to Safemode anything.

It look like a MBR curruption I dont know. I even tried to repair one of the server and it did not work after repair it goes back to the same message "A disk read error occurred Press Ctrl+Alt+Del to restart" . My VMFS are correctly partioned aswell.

Please help

that offset is large. But is divisible by 4KB (depending on your storage system).

try using gparted http://gparted.sourceforge.net/download.php to move the partition back to 32256 or 32768.

as you can see Windows default is 32256, we normally align to 32768 which is divisble by 4KB.

I would try to use fdisk to set the partitions back to their original starting value.  Do you know what changes the PAT makes?

Rollback using a Backup. and test the software product on a test machine in future.

I usually use gparted to align partitions if needed. (if there are performance issues with the VM on the LUN) which have been detected.

The Backups ate in a offside location , it will take a while to get it.

The PAT tool reAligns the partition and it worked in many VMs.

If I add this HDD as a slave to an other VM I can see the data. Is there a way we can change the offset to unaligned back again ??

You could use diskpart or gparted (bootcd).

what is the OS, and what's the partition been aligned to?

Hi ,

The attached file :

 Has 2 HDD . the 1st one is Not aligned and I added the vmdk of the failed machine as a slave a xp VM (not aligned) looks like the offset is not correct in the VMDK file. Is this correct can we roll back this offset to the 32256 bytes ???

just make sure you have a backup before making any partitions modifications.

I get this error while resizing. When I checked other forms they said to do a clean shutdown of windows and it will work fine but im not even able to login to windows because of this problem..


Log:
ntfsresize -P --force /dev/sda3
           
ntfsresize v2.0.0 (libntfs 10:0:0)
ERROR(95): Opening '/dev/sda3' as NTFS failed: Operation not supported
The NTFS journal file is unclean. Please shutdown Windows properly before
using this software! Note, if you have run chkdsk previously then boot
Windows again which will automatically initialize the journal correctly.

is this error generated within gparted?

if so, why not complete a chkdsk using the attached disk VM method?

gs1ukAuthor Commented:
Yes, this is a message from GParted.

Ok Let me do a chkdisk in windows and get back to you .. Thanks for your time..

You could also try a trail of Quests vOptimizer Pro, it does the same thing, disk alignment, and you get 5 free alignments with the trial download.

If the above doesn't work for you also, you'll have to resort to a Backup you took before using teh PAT tool.

you could create a new aligned correctly partition on a new disk attached to the machine, and perform a file copy from one disk to the new one.
