I run a few fio commands to test write speeds of my ssds. Unfortunately, I learned that after this the disks are not available anymore, thus the pool is offline.
root@truenas-scale[/home/admin]# zpool import
pool: applications
id: 11734411687122568160
state: UNAVAIL
status: One or more devices contains corrupted data.
action: The pool cannot be imported due to damaged devices or data.
see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-5E
config:
applications UNAVAIL insufficient replicas
mirror-0 UNAVAIL insufficient replicas
4be538f8-3c73-4c98-a395-4e3c6b3fcee6 UNAVAIL
nvme0n1 UNAVAIL invalid label
Can you please post the exact fio command you ran?
If it included a part similar to --filename=/dev/sdX and you used it on a drive with data on it, you’re probably SOL. In that case you will have to use a backup, if any exists. Even a snapshot won’t help you.
