The Story

I needed more disk space on my vinum volume, which I created about 18 months ago using 2 IBM DeskStar 30GXP 30GB ATA100 drives. Originally, I created a RAID 0 (stripe) filesystem on top of these drives using vinum. But now I needed more disk space for various processes that I was running on the machine. So I got a new IBM DeskStar 80GB ATA100 drive.

Just like the FreeBSD diary article on vinum, I had an /etc/vinum.conf. Its contents were: Continue reading »
