I have used ZFS for four years on (Open)Solaris, so I have some experience with it. It always served me very very well. However, I cannot get it to work on my SATA2 drives. At first I thought they'de suffer from something from there OpenSolaris ZFS mirroring. So, I wiped out the drives completely by writing zero's to them. Then I created a ZFS zpool on one drive, destroyed it and created a mirrored zpool on my 2 Tb drives. It seemed OK; files could be written and removed to/from it. A new zfs filesystem worked OK too. *HOWEVER*, the moment I *do* something to the zpool like "zpool scrub pool" I get a vdev failure (type=vdev.bad_label) and the pool is ruined. It can't be destroyed or exported anymore. It's just a waste. I tested this behaviour on 10 different drives. Four of them brandnew. It happened everytime again. It is not the drives! Booting into OpenSolaris b134 I am perfectly able to create workable ZFS mirrors out of the drives. I can also scrub them ;-) ;-) or whatever io related thing I want to do. This leads me to the conclusion that something is definitely wrong with ZFS in FreeBSD-8.1/amd64. For the moment I created some gmirrors on a couple of drives, but man, how I'd liked to have zpools. They work zo much sweater/easier. Am I alone in these matters? Are there any known issues regarding ZFS. I know there are some in FreeBSD-9 (at least I saw some reports on vdev.bad_label messages) on nabble.com
