I have been trying to trigger automatic disk replacement from hot spare pool without success. I attempted two things -
1. modify vdev_fault_arg, vdev_fault_mask and vdev_fault_mode (VDEV_FAULT_COUNT) Errors (ereport.fs.zfs.io) are logged, zpool status shows them, but nothing else happens. 2. modify vdev_is_failing, again nothing happened. Any pointers will be appreciated. Regards Bhaskar
