As far as I remember, partitions were not deleted, it's just metadata. Quick online search for "dmraid -r -E" never mentions data loss neither, so you should be fine. BUT, if you can, backup would be preferable for any live work with important data, and "sfdisk -d /dev/sdX > partition.txt" will save partition info so if anything goes wrong you can reapply it. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe StarOS, Mikrotik and CentOS/RHEL/Linux consultant
