After attempting unsuccessfully to replace a failed drive in a 10 drive raidz2
array and reading as many forum entries as I could find I followed a suggestion
to export and import the pool.
In another attempt to import the pool I reinstalled the OS, but I have so far
been unable to import the pool.
Here is the output from format and zpool commands:

cannot import 'storage': one or more devices is currently unavailable
Destroy and re-create the pool from
a backup source.
Prior to exporting the pool I was able to offline the failed drive.
Finally about a month ago I upgraded the zpool version to enable dedupe.
The suggestions I have read include "playing with" the metadata and this is
something I would need help with as I am just an "informed" user.
I am hoping that as only one drive failed and this is a dual parity raid that
there is someway to recover the pool.
Thanks in advance,
Kevin
