симптоматика проявилась после появления сбойных секторов на одном из винтов, решил затереть сбойные сектора через dd, но тут меня ждал подвох тк видно именно там были метки;-( короче ситуевина вот такая:

        Additional devices are known to be part of this pool, though their
        exact configuration cannot be determined.

ну и напоследок, как понимаю нужно отклонировать LABEL на новый диск, и тогда наступит счастье, но как это сделать не совсем понятно
ПС тут ссылаются на некую магическую тулзу Jeff Bonwick's labelfix binary(https://www.mail-archive.com/zfs-discus ... 49014.html), но найти пока не удалось
ППС нужен практический совет, тк второй попытки не будет

коллеги а кто в критических ситуациях пользовал данное средство:

You can run it with a dry-run option to tell you how many
minutes of transactions will be lost:

# zpool import -nFX pool-name

This might take a very long time. The -F option is the recovery
option. I think the -X option scrubs the entire pool. Then,
you can run it like this:

# zpool import -FX pool-name
