Re: RAID0 recovery on VAIO-AR71ZU

Thank you for your answers. After changing the electronic controller from disc, it appears to be a RAID issue (according to the person who changed the disc). Assembling in the BIOS does not work. So is it still possible to reassemble the RAID array in r-TT?

One thing for sur I will only work with ...

Dear all,

I need to recover the RAID 0 system of a VAIO-AR71ZU.
This is a harware RAID 0 defined in BIOS and The OS is Windows 7.
The RAID is NOT managed by Windows software RAID.
The disc system should be NTFS.

I don't have access to the discs (yet).

The RAID array contains YEARS of work of a ...

Re: Recovering lvm over RAID5 Linux using R-Studio

This was a UID problem, I created a new pv.
Then I could import the lvm configuration file.
And rebuild volumes.

Then I mounted the volumes, but the ext3 filesystem was not recognised.
Do you any tool or method to recover a destroyed lvm?
The RAID5 data is still there.

Re: Recovering lvm over RAID5 Linux using R-Studio

Before of a poor copy, there were errors in the configuration file.
It is highly important that R-Studio could allow text copy.

Here is the right configuration:
contents = "Text Format Volume Group"
version = 1

description = "Backup"

creation_host = "supermicro-formalib"
creation_time ...

Re: Recovering lvm over RAID5 Linux using R-Studio

I searched for "logical_volumes {" string using text/hexadecimal editor and quickly found the file.
There are several versions of the same file.
The trick is to find the lasted backup.
It is quite easy as the text includes the date in Unix format.

I copied the text file and pasted it ...

Re: Recovering lvm over RAID5 Linux using R-Studio

I need to search for the lvm backup file.
It should look like:

physical_volumes {

pv0 {
id = "rVNFt0-YYRQ-cz2n-igAB-MD3f-Edni-5x2Qqt"
device = "/dev/sda5" # Hint only

status = ["ALLOCATABLE"]
flags = []
dev_size = 770015232 # 367,172 Gigabytes
pe_start = 384
pe_count = 93995 # 367,168 ...

Re: Recovering lvm over RAID5 Linux using R-Studio

Hello again,

R-Studio was able to create virtual partitions.
So I should be able to extract the content of my lvm partitions.
But it should take hours.

I am not sure to go this way, as my RAID array is synchronized.
All data is there, I only need a working lvm configuration.

The lvm backup file ...
