I was able to create a zpool and then created a zfs filesystem (BTW, thanks to all those who helped me get by the hard drive formatting issues I had posted here earlier).
I read that ZFS does variable block size, that is, a user can specify a blocksize, and if a file is smaller than the user specified blocksize, the file would be the smallest power of two between 512 bytes and the user specified blocksize.
Just how would I specify the blocksize? Is that an option I have to use in the zpool create command?
