Need to recover files that are accidentially deleted? Who hasn't dropped over 103 mysql databases by typing in the wrong commands at one point or another? Here's my recommendation:

• testdisk.
• ext4magic
• r-studio

PROCEDURE
====================================
=============
-lvm vgscan
-lvm lvscan
-lvm vgchange -a y
-lvm pvscan
-lvm lvscan
-lvm vgrename main mainold
-exit

=============
fdisk -lu /dev/sdb
mdadm -AR /dev/md8 /dev/sdb2
lvm vgscan
lvm lvscan
lvm vgchange -a y
mkdir -p /mnt/olddrive
mount -t ext3 /dev/mainold/root /mnt/olddrive

RECOVERY
====================================
ext4magic -R -f /dev/olddrive/var/lib/mysql -d /installs/RECOVERDIR1
ext4magic /dev/olddrive/var/lib/mysql -j /installs/BACKUPPATH/journal.copy -d /installs/BACKUPPATH -m -R

??????????
ext4magic -R -f /dev/olddrive/var/lib/mysql
ext4magic -R -f /dev/mapper/mainold-root var/lib/mysql
ext4magic -R -f /dev/md8 var/lib/mysql
ext4magic -R -f /dev/sdb2 var/lib/mysql
ext4magic -R -f var/lib/mysql
