36% of data loss is due to human error. 49% of data loss was due to

addresses most of the 49% of data loss due to

Note that zpool destroy can be undone by zpool import -D (if you get
to it before the disks are overwritten).

Going back to your USB remove test, if you protect that disk
at the ZFS level, such as a mirror, then when the disk is removed
then it will be detected as removed and zfs status will show its
state as removed and the pool as degraded but it will continue
to function, as expected.

Hey Brent,
On the Sun hardware like the Thumper you do get a nice bright blue ready to
remove led as soon as you issue the cfgadm -c unconfigure xxx command. On
other hardware it takes a little more care, I'm labelling our drive bays up
*very* carefully to ensure we always remove the right

Hello Ross,
I know personally many environments using ZFS in a production for
quite some time. Quite often in business critical environments.
Some of them are small, some of them are rather large (hundreds of
TBs), some of them are clustered. Different usages like file servers,
MySQL on ZFS,
I have done a bit of testing, and so far so good really.
I have a Dell 1800 with a Perc4e and a 14 drive Dell Powervault 220S.
I have a RaidZ2 volume named 'tank' that spans 6 drives. I have made 1 drive
available as a spare to ZFS.
Normal array:
# zpool status
pool: tank
state: ONLINE
Hey folks,
I guess this is an odd question to be asking here, but I could do with some
feedback from anybody who's actually using ZFS in anger.
I'm about to go live with ZFS in our company on a new fileserver, but I have
some real concerns about whether I can really trust ZFS to keep my data

We have 50,000 users worth of mail spool on ZFS.
So we've been trusting it for production usage for THE most critical visible

Works fine. Our stores are ZFS RAID-10 built of LUNS from pairs of 3510FC.
Had an entire array go down once, the system kept going fine. Brought the
