I've seen too many cases of people reporting breakage in tool X and then upon further probing it turns out they indiscriminately used the '-f' to make their immediate problem go away, and then some time later there's a lot of tears over lost data. [1] But I digress. The point that I failed to make is that in my mind there's more to the problem that started this thread than the original statement of: I have accidentally formatted one of the drives in exported ZFS pool. [2] Having said that, in the process of trying to replicate the problem I've learned a lot more about ZFS than I knew before the report, so for that I'm grateful. > If you force it, it will add a vdev not the same as the current > vdev.

Thanks, that seems like ample reason to reinforce my dislike of invoking the '-f' option on tools. [1] There's no evidence at this point to my knowledge that the reporter used '-f'. I'm making a general statement. [2] http://lists.freebsd.org/pipermail/freebsd-fs/2014-April/019339.html -- Hugo Lombard .___. (o,o) /) ) ---"-"---
