Multipath autoreplace, control enclosure LEDs, event rate limiting
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.

The default behavior is "\fBoff\fR". This property can also be referred to by its shortened column name, "replace". Autoreplace can also be used with virtual disks (like device mapper) provided that you use the /dev/disk/by-vdev paths setup by vdev_id.conf. See the vdev_id.conf man page for more details. Autoreplace and autoonline require libudev to be present at build time. If you're using device mapper disks, you must have libdevmapper installed at build time as well. .RE .sp |
