1. Enable multipath autoreplace support for FMA. This extends FMA autoreplace to work with multipath disks. This requires libdevmapper to be installed at build time. 2. Turn on/off fault LEDs when VDEVs become degraded/faulted/online Set ZED_USE_ENCLOSURE_LEDS=1 in zed.rc to have ZED turn on/off the enclosure LED for a drive when a drive becomes FAULTED/DEGRADED. Your enclosure must be supported by the Linux SES driver for this to work. The enclosure LED scripts work for multipath devices as well. The scripts will clear the LED when the fault is cleared. 3. Rate limit ZIO delay and checksum events so as not to flood ZED ZIO delay and checksum events are rate limited to 5/sec in the zfs module.
