Trying ZFS 

Trying ZFS

well, today was my first time with ZFS, since i dont have a biig disk available or any free slices I just used regular files, I used 200mb files in fact and here is how i created my first ZFS mirror
first, let's create the files
root@darkstar:/export # mkfile 200m testfs1
root@darkstar:/export # mkfile 200m testfs2
now let's create the pool and the mirror
zpool create test mirror /export/testfs1 /export/testfs2
finally let's change the mount point and turn comression on
root@darkstar:/export # zfs set compression=on test
root@darkstar:/export # zfs set mountpoint=/export/test test
root@darkstar:/export # zpool status
pool: test
state: ONLINE
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
test ONLINE 0 0 0
mirror ONLINE 0 0 0
/export/testfs1 ONLINE 0 0 0
/export/testfs2 ONLINE 0 0 0
all looks good but let's check the value of the properties of the zfs pool
root@darkstar:/export # zfs get all test
NAME PROPERTY VALUE SOURCE

test snapdir visible default
test aclmode groupmask default
test aclinherit secure default

that was easy wasnt it? ;)
I will play more with it later
I will tell you about my failed experience using ZFS and lofi exported file, hint: it didn' result quite as expected, specially when i tried to cat /dev/random the lofi exported file
