Alfred's New Ramblings

A rare problem (hopefully).

This is something, one hopefully will never encounter.  A corrupted RAID  5 stripe.

RAID  5 works by storing data in logical stripes (64 or 128KB) with parity across the set of harddisks.  This is usually 3 to 6 disks.  If any of the disks were to fail, it can be replaced and data recreated from the parity bits.

It is also possible to have a corrupted logical stripe or punctured stripe as Dell calls it. This when the RAID controller does a hiccup. The only solution is to backup, wipe, re-create and restore.  Yes. Ouch.

Dell has released a utility to fix this.
