Now I trying to figure out how to safely import my old pool(raid-Z2) from freebsd 8.2 to Zfsguru..as I dont have any backups of this 11TB pool(to big). Any suggestions?

You can just import the pool in ZFSguru. I do not consider importing pools in ZFSguru created by other systems or platforms to be a risk of any kind. These things should just work, and should be very safe to do.

In fact, it is dangerous to leave a pool unimported. Once a pool is imported, you cannot just write to the physical disks the pool is made of. But if a pool is not imported, it is not known by the operating system. This means you could make a mistake and format the wrong disk, for example. If you try to do this on a disk in-use by ZFS, the format command will fail with permission denied error.

Thx for reply. Im just in curious situation as I have original zfs pool on old Dell PERC 5/i raid card running disks in jbod mode and different connection cables than I have in new build. So I need pull out dell card from old machine a put it in pci-e slot in new machine...disk will stay in old case during copy operation oldpool->newpool. After this a will wait few weeks and see how stable will be new build with new disks and with zfsguru. If everything will run nicely a will put old disks in new case and create second pool from them.
Btw Jason I send you few ideas during activation mail....what do you thing about that? :)

I added second RZ2 with 4K on 11x2TB Samsungs and with default 64GB benchmark I get 650MB/s read and 560MB/s write... But when I copy 10GB file between two RZ2 I get only 150MB/s which is absurd.
Whats wrong?

Once your child enters middle school, you may give them a little more freedom when it comes to video games. However, it is important to still be aware, particularly when it comes to multiplayer games. Listen to make sure the language is appropriate. If not, take off the option for online play.
