Hello experts, I am in desperate need of assistance. I encountered the following issues:

1. Initially, the system was functioning smoothly. I powered it down to install a heat spreader on the NVMe drive.
2. Upon rebooting, I was surprised to discover that two cache pools were displaying the same error message: "Unmountable: Unsupported or no file system." Consequently, all other files on the cache pool have become inaccessible, and Docker is also currently offline. Your help would be greatly appreciated.

Bignfast prior to reboot is on zfs mirror

Superfast prior to reboot is on zfs

Type:
 

zpool import -f bignfast
zpool import -f superfast
zpool export bignfast
zpool export superfast

Then re-start array

 

BTW, any idea why the pool devices were all unassigned at boot?

Thank you, your advice worked. 🙂

 

Following the initial restart, I encountered the "Unmountable: Unsupported or no file system" issue. In my efforts to resolve this problem, I made multiple attempts to remove the cache, restart the system, and then reassign it.

 

For educational purposes, I'm curious to know if I made any mistakes that led to this issue. Could you please explain why this problem occurred and how it wasn't automatically resolved by UNRAID?

Not sure why it happened but zfs though the pools were used in a different system.
