Managed to import my pool BIGHDD throught the command [zpool import -f -F -N -X -R /mnt -o readonly=on BIGHDD]
Regular imports were not working and would crash truenas and reboot
Im trying to figure out how to get the data off this pool and into another drive.
Alternativly I have these snapshot that I can roll back from but I'm not sure which is the best route to go on since the rollback can possibly distroy all the data.
If anyone is able to provide some guildence, it would be much appreciated.
