Hi all,
I’m running TrueNAS Scale ElectricEel 24.10 in my ESXi virtual machine. Its boot volume is a 32GB VMDK image.
My issue is, I’m frequently seeing the error message says Boot pool status is DEGRADED: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected..
In the /var/log/error I see a lot of these error messages

Could you instruct me what I should check next? How can I solve this error?
Thanks!
