Andrea,
I have started testing with gstripe and have had good results to
this point. 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!
Nick
