You may still have a slight chance to repair the broken RAID volume.
What is the type and model of RAID controller? What is the model of the
drives? Did you aggregate the RAID arrays with LVM?
Most drives failures (particularly on late 2009 Seagate SATA drives) are
both relatively frequent and transitory, i. e. may randomly recover
after a while.
What did you try? Can you power down the faulty RAID array
entirely and power it up after a while? Did you try to actually freeze
the failed drives (it may revive them for a while)? Did you try to run
SpinRite or another utility on the broken drives, individually ?
