[sclug] Better than RAID?

The functionality that caught my eye was:

    o Bad Block Relocation

Well that sounds like a good reason to switch to LVM2.  But
how quickly
will the features be back ported.
 From this Sourceforge page:
The current stable version of EVMS is 2.5.3. It was released on June 10, 
2005.
It looks like EVMS is still being worked on.

Yes, I was impressed by this approach to handling errors.
For the time being I will go with the flow and use Linux RAID.
If I experience lots of spurious problems I might well switch to BSD.
