I catch this error when exec the task, then my sandbox is broken, I have try to stop and run sandbox container and it's still broken.

[1/1] currentAttempt done. Last Error: USER::The node was low on resource: ephemeral-storage.

could you share the output of

kubectl get pods -n flyte

@Kevin Su I have rebuild the sandbox to evade it. But may be it's broken because my SSD storage is not enough, it's take about 92% when my sandbox was broken and re init the sandbox still broken. I have to prune all container and volume to fixed again. I want to ask you more, when I re-init the sandbox, all my old workflow still exist, I want to know where is the place storage it.

you can always do

flytectl demo teardown --volume

if you want to get rid of that space.
