Este guia irá mostrar como você pode instalar um ambiente completo e funcional com ZFS usando o esquema de particionamento GPT no FreeBSD 9, nós também iremos usar SWAP em ZFS.
Você pode usar este guia como referencia para uma instalação simples ou em espelhamento (mirror).

tPPVRvqoVpgwvNywtx Por Charlene em 19/03/2012 14:06:03We split the disks between two RAIDZ2 pools with 5+1 in each pool. We joeind both those pools into one large ZFS pool.Performance is mixed. Under some workloads (random writes, for example) it solidly trounced every other system we have benchmarked, including a variety of RAID cards in various configs (0, 5, 6, 1+0) and other software RAID solutions including gmirror and gmiror+gstripe. In other workloads, it was significantly slower when compared to benchmarks of this same 320S with 5 software RAID-1 mirrors (geom_mirror) striped in a RAID-0 array.We had two separate needs we were testing for: a great big disk for storage and a high performance file system for MySQL. The results is that we use ZFS for file storage type application and a combination of hardware RAID-1 mirrors striped in RAID-0 via gstripe.

When the root partition is read only, its pretty difficult to end up in a state where the system won't boot up and become remotely accessible. With a system that has no KVM, that's a nice little benefit. I don't just do that with my Soekris systems. I have system with 24 1TB disks in it that boot off of a read only CF card. It also makes it a bit more difficult for a less experienced sysadmin to make changes that cause problems.I've put RDBMS on flash based media, but that was much newer SSD storage. It's nice because you get really fast read transactions. With CF, your writes will be terribly slow. That may or may not be a problem for your workload.
