Author: pjd Date: Mon May 31 23:17:45 2010 New Revision: 208683 URL: http://svn.freebsd.org/changeset/base/208683 Log: Fix a bug where resilver is not started automatically on pool import or load. If disk was missing on pool load or import and on next pool load or import it was present, resilver wasn't started automatically and ZFS reported all disks as ONLINE and healthy. Then, when another disk died, pool became unaccessible, because if it was 2-way mirror or RAIDZ1 two vdevs were out of sync. To fix the problem, start resilver automatically on pool load or import.
