Reply - You don't have to leave the 10% but I would leave at least 5%.  I
would imagine when the disk is near full fsck may not work with enough
"extra" space to use.  Just like defraggers and scandisk's, etc. in windows.

	Hello,

	I'm not totally familiar with RAID0, but I do know that when Solaris
makes
	the new files system (using 'newfs'), many superblocks are created
on the
	disk for redundancy.  This ends up taking up some space as well.

	There is a way to optimize this. According to my sys admin book:

	"NOTE - The newfs command will 'reserve', by default, 10 percent of
the disk
	space for file system maintenance.  This can be adjusted by using
either
	newfs -m # option during creation of the file system or tunefs after
after
	the creation of the file system. "

	See the pertitnent man pages to do this.  I normally don't play with
this.

	Regards,
