There is a starting point here which you may find helpful: http://debian.co.nz/Recovery+of+RAID+and+LVM2.html http://tldp.org/HOWTO/LVM-HOWTO/index.html http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html (I'm assuming here you were using software RAID; if this was a hardware RAID setup, then you need to know what sort of low-level format was used by your hardware RAID device.) - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
