Erik,

because most of the ATARAID formats don't keep  names for the RAID
sets/devices, I need to make up a name from other members of the
metadata and I chose the timestamp and incarnation # to derive the name from
for the sil metadata format handler, not knowing that the closed source
Windows driver changes that # every time.

Looks like removing the incarnation # form the name generation makes sense...
Any comments on this ?
