8 11 00 1953503711 16384 1953520094
I've read the thread, and in it there's an advice to either:
1. Restore original labeling on the c7d0 disk
2. Remove (physically or logically) disk c7d0
And well, I'd have to remove all three disks if I used the second
advice, since they all have missing labels on c14d0 identically. Which
leaves me with restoring the original labeling. How do I do this? What
actually prevents zfs from importing my pool?
Thank you!
