We'd need to know how your storage is configured. Everything from how storage is connected to the system (if it's external) or if you're using an internal RAID controller. What sort of mirroring are you using, how many locally connected HDD drives do you have, how are the clustered file system

Luis, You still haven't provided the relevant details of your configuration. The df output you provided isn't relevant in terms of the data recovery. You haven't even mentioned what file system the lost data was on. You mention mirroring - what was doing the mirroring? Hardware RAID? Softwar
