As the pool name is known we could run:
zdb -C poolname
to get the pool's configuration, which includes the path to all members of all
(available) vdevs.
To get the configuration of a known, exported pool we could use:
zdb -C -e poolname
This will work as long as the pool is not imported and its devices can be found
in /dev/.
Sample output follows:
root@sbooblehat:~/zfs# zdb -C sbooblehat-rpool
