In fact, that space_cache rebuild might be why you were seeing such high I/O after the reboot and fresh mount. If the space-cache rebuild is all the problems you see, you may be lucky, and the hard-terminated delete and reboot might not have resulted in any permanent damage. OTOH, if it seems the space_cache rebuild is interfering with further activity for too long and you end up doing another hard reset anyway, there's the nospace_cache mount option to turn it off.
