zfs discuss - Jul 2009 - Status of zpool remove in raidz and non-redundant stripes

You''re right - in my company (a very big one) we just stumbled across
this as well and we''re strongly considering not using ZFS because of
it.

It''s easy to type zpool add when you meant zpool replace - and then you
can go rebuild your box because it was the root pool. Nice.

At the very least, "zpool add" should have more warnings.

I second that.
This is exactly what happened to me.
There is a bug (ID 4852783) that is in State "6-Fix Understood" but it
is unchanged since February 2010.
