There's also this, which has me thinking gvinum doesn't support 4k sectors yet: % grep -n sectorsize ~metis/sys/geom/vinum/geom_vinum_subr.c 1068: pp->sectorsize = 512; /* XXX */ Anyhow, the last time I had to prepare a large, diverse pool of storage was during the 5.x branch, so I was trying to work with what I was familiar with (vinum). And due to budget constraints, I'm stuck using i386 32-bit for the time being, so ZFS wasn't really an option. After some research, I've got a much better understanding of how the GEOM components fit together, and I must say that I'm quite pleased with what I've found! I have since decided to give sysutils/graid5 a spin, and so far it's doing exactly what I had hoped to accomplish with vinum (including using regular disk partitions as subdisks, which I intended to get to eventually). I have 2 questions regarding graid5: 1. Why hasn't it made its way to the base FreeBSD distribution yet? 2. Has anyone done any rigorous testing with it? -- Anthony Chavez http://hexadecagram.org/ mailto:acc@hexadecagram.org xmpp:acc@hexadecagram.org
