I suspect this pool has one dead disk (missing)

dev.c:204:vdev_dbgmsg_print_tree(): vdev 3: disk, guid: 16135456112045096637, path: /dev/disk/by-partuuid/6346765b-4a5a-4282-afd1-744acc2014c4, can't open

and another that has errors and since its a Z1 pool there isnt enough parity to do the import. So this is a nice way of saying you are likely restoring from backup, sorry its not better news. Dont use Z1 unless its not important data.

You may be able to import the pool with -F (assuming you're prepared to lose the last few transactions to get there.

zpool import -F TANK_SATA

zpool import -F TANK_SATA

I trie -F or -fF or -f -m -F and always error "action: The pool cannot be imported due to damaged devices or data."

 

[sretalla]

OK, well that sounds pretty definitive then...

You might want to consider if you need the data or not... tools like Klennet https://www.klennet.com/zfs-recovery/default.aspx (paid tool which offers a look at recoverable content before requiring payment... runs on Windows) or depending on how lucky you're feeling, this tool... https://github.com/Stefan311/ZfsSpy.

It looks like all the "data" drives are there just the one cache drive is causing problems. I assume it was mirrored and now it looks like corrupted data since one half of the mirror was formatted.
Just a shot in the dark - try disconnecting those cache drives and try importing without them. Also try googling importing zfs pool without cache.
Disclaimer: I have no idea if any of this will help and this is way beyond my knowledge level but I remember seeing some threads about importing ZFS without cache somewhere. I can't help you myself but maybe this will point you in the right direction.

j'avais tenté de faire l'import sans les disques en mirror sans succes. J'ai meme recrée la meme partition, changer le partionID et copier les data de l'autre disque SSD pour avoir un pseudo mirror mais le systeme bloque en disk Corrupt....
Je crois que c'est meme pas des disques Cache mais des disques en Metadata
------------------------
Thx, i tried without cache disk not succes. I tried to recreate a partition ZFS with other disk mirror but zfs block on disk corrupt.
It's not CACHE disk, it's METADATA (Special) disk.
i trie with Klennet ZFS.
