I'm still a little unclear about how to make my stripe persistent after a reboot? My server consists of three drives. A 40GB drive that has the operating system and two 200Gb drives that I'm using for the raid 0 volume. I was also curious about a couple of other things. - There is a .snap directory on the volume. Is this used by gstripe? - I changed the mode to fast and didn't notice any difference in my basic performance testing. Is there any advantage of using fast? - I used newfs -O 2 to create a UFS2 file system on the volume. Is this treated like any other UFS2 volume that can utilize fsck, etc? - How resiliant is this volume if the system were to crash? --Thanks!
