zfs discuss - Jan 2006 - Dumping pool configuration for D/R purposes

In the ZFS admin guide under the topic of Repairing Pool Wide Damage it talks
about in the event that it''s not possible to open the pool you have to
scrap it, re-create it and then restore from backup. To do this it mentions
keeping a file that describes the layout of the datasets and locally set
properties and the details from a zpool statis. Is there no command, or
possibility of one to dump the config of a pool out to a flat file that can be
used to re-create the pool under such circumstances - like the options off
vxprint to dump the disk group configs and then re-create them via vxmake - or
is the only option to keep a manually updated text file somewhere on the
server???

You''re looking for the following RFEs:

6276912 zfs config
6276640 zpool config

They''re current not on my radar anywhere, but I''ll likely take
a look at
them in a few months.
