What about removing attach/deattach and replace it with
zpool add [-fn] 'pool' submirror 'device/mirrorname' 'new_device'
e.g.
NAMESTATE READ WRITE CKSUM
rpoolONLINE 0 0 0
mirror-01 ONLINE 0 0 0
c4d0s0 ONLINE

I support a replacement for a SCM system that used "open" as an alias for
"edit" and a separate command, "opened" to see what was opened for edit,
delete, etc. Our customers accidentally used "open" when they meant "opened"
so many times that we blocked it as a command. It saved us a lot o

Currently, you cann
Hi,
I wanted to add a disk to the tank pool to create a mirror. I accidentally used
zpool add … instead of zpool attach … and now the disk is added. Is there a way
