These are the conditions: (1) The bug is specific to the root pool. Other pools are unaffected. (2) It is triggered by doing a 'zpool online' while I/O is in flight. (3) Item (2) can be triggered by syseventd. (4) The bug is new in build 102. Builds 101 and earlier are fine.
I believe the following should be a viable workaround until build 103: (1) svcadm disable -t sysevent (2) Don't run zpool online on your root pool Jeff On Sun, Nov 16, 2008 at 03:12:03PM -0600, Gary Mills wrote: > On Sat, Nov 15, 2008 at 05:41:56PM -0600, Al Hopper wrote: > > Heads up! and apologies to folks subscribed to os-announce. > > Argh, and I just live-upgraded to build 102.
