data-recovery

This was me being stupid and the data is by no means critical and is now a learning experience first, time saver second.

I set up a 100GB iSCSI target via the bare bone instructions in napp-it. It's a volume LU.

I then had my Windows 7 machine connect to the iSCSI target, formatted it to NTFS, and tested the performance of it with some large iso file transfers. I then unmapped the drive, reconnected to the target, and was forced to format to NTFS again.

It was then I realized the files I had transferred only existed on the iSCSI target. I threw a little fit and then went about my business. When I was cleaning up my experiment I noticed in this screen: http://imgur.com/1xlcu.jpg

That is my experimental target tank/iSCSI and it still has a lot of data in it.

Assuming my isos are still in this pool how would I go about recovering them?

While writing this I used GetDataBackup for NTFS from www.runtime.org. And while it found two previous NTFS partitions there was no data.

Can single ESXi host make use of two separete iSCSI box?

Hi! I have problem with using multiply iSCSI targets with single ESXi host (in my case they are two FreeNAS hosts, but I suspect that this problem will occur with any two iSCSI box of that same type/model). If I configure two FreeNAS hosts as iSCSI targets (say iSCSI A and iSCSI B), then I can use… >>> More
