Run a pool verify or rebuild using ravsui and interrupt the verify process using Ctrl-C. This command kills the ravsui process in user space but does not kill the background verify or rebuild kernel threads. Pool activation will succeed only after these background threads complete.
You can reattach the ravsui UI to the background running thread using the ravsui -a command. This will reattach the ravsui UI to the running rebuild or verify thread and the progress will be shown.
