From d02ca379795a37b8541da5a1b37528f7130de1e6 Mon Sep 17 00:00:00 2001 From: Don Brady Date: Wed, 31 Aug 2016 15:46:58 -0600 Subject: Bring over illumos ZFS FMA logic -- phase 1 This first phase brings over the ZFS SLM module, zfs_mod.c, to handle auto operations in response to disk events. Disk event monitoring is provided from libudev and generates the expected payload schema for zfs_mod. This work leverages the recently added devid and phys_path strings in the vdev label.
