Ubuntu overwrite mbr of a XFS-Dmcrypted-Raid 1 disks. How recover data?
Hi to all, my name is Marco.
Some time ago I set up an encrypted system with two 320 Gb disks on raid 1.
I created the raid 1 system with mdadm, I encrypted the hole new device with dmcryp and in this I built an XFS partition using all 320 Gb.
I used this encrypted disk to backup my personal data and other things. Software and system was on another hd, where it was installed Slackware. Unfortunately, I had problems with the Slackware, so I decided to remove this and install the last version of Ubuntu, just to try, on the partition where was the Slackware (I used the manual partition, I haven't touch the other disks). After installation I removed Ubuntu (I didn't like it), and I used Slax to access to my crypted disks, and than, after have assembled the raid 1 and create the mapper, I found out that I can't mount the xfs system.
I tried with fdisk and it can't find any partition, I have done a scan with testdisk on SystemRescueCd but it can't find anything.
After a lot of tests I find out that if I try to boot the pc with the 320 Gb disks, on the screen came out a Grub error. So I think that Grub have overwrite the mbr of the 320Gb disks, but I used all the disks as an encrypted device, so Grub must have overwritten encrypted data.
I would recover the data on the disks, can anyone help me???
Thank you for your time.
