and why you need to destroy and re-create a pool

You do not say why need to destroy the pool.

But easy and only way is to copy data to other site ( other pool, and external HD, etc...), destroy pool and recreate it

Why i say this is because when i run zpool import -f hdc i get an output saying this.

So how save the data 770GB of series?

Is there any options to create only ada7 in read only mode to access the data and copy?

no.

and because how ZFS works , I'm totally sure that your series are not only in one drive ( I'm sure that are split in the 3 disk that you use to create the pool).

So your atemps can be in the direction of import your hdc pool and recover your valuable data.

please keep in mind that RAID of any kind ( including ZFS raid) IS NOT a BACKUP.

If your data is valuable , you need to have copy of then in other physical places.

Please post your problem with import hdc

Is like if your metadata are corrupt, if is your case, you are lose your data, your option is recreate the pool and copy data from a backup.

some links from google:

http://askubuntu.com/questions/99266/wh ... d-zfs-pool
http://comments.gmane.org/gmane.os.sola ... .zfs/44594

Perhaps some switchs like -R or -fF -R can work, please google a bit and try before to do the data lost.
