I was able to mount the pool using zpool import -f -o readonly=on -R /mnt Tank
Then using SFTP over SSH and filezilla I was able to connect to the pool and start copying the critical data off
Just got to hope it holds together until I get the data off that I need
The next thing is finding the root cause and then rebuilding.
I’ve ordered a synology nas to set up as a backup so that I don’t have this happen again without a backup of my critical files
I’ve still got a long way to go but it’s looking positive
