How to recover data from StarWind SAN&NAS

[valerymartyshko]

Hi! I need to recover data from a crashed RAID with StarWind SAN&NAS operating system. How to recover data from a RAID level 5 with the XFS file system?
Are there specific tools or methods recommended for data recovery from a virtual NAS like StarWind SAN&NAS?

Hi,
Sorry to read that. Could you please tell me more about the issue and how exactly you ended up with corrupted data?
Also, how does the corruption of data manifest itself? Are those the VMs who cannot start or anything like that?

yes it is, the virtual machine does not start. At some point, it simply stopped loading.

By the way, I have already found some programs that can read damaged disks of virtual machines. I will test it now.

Thanks for your update.

Is it SAN and NAS VM or the client VM? If that's Starwind SAN & NAS VM, having a screenshot of the error will be helpful.
May I wonder what was done before the incident?

It is a client VM (VMWare).
The error appeared after the equipment was turned off, as a result of a power failure.

Hi,

Correct me if I am reading it wrong. You have an issue with booting a StarWind SAN & NAS VM, not the client VM.
It looks like you got a snapshot corrupted, meaning that the issue is to be addressed on the virtualization layer (i.e., outside the SAN & NAS world). Can you please try changing the config to read from the bulk virtual machine disk, not from the checkpoint (beware of data loss).

Please let me know how I can do this. I didn't quite understand

What hypervisor you use?

I came across an article about data recovery from StarWind SAN&NAS. In it, data was restored using the program - Hetman RAID Recovery. I downloaded and mounted the disk of my idle virtual machine to it. Program read it and displayed my data.

If you help restore the virtual machine, I will be grateful. If it doesn't work, then I will restore the data with this program.

Hi,

I think the easiest way will be restoring data with the third-party app you mentioned.
