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.
