You can simply upgrade to FreeBSD 8.2-STABLE (you are running 8.2-RELEASE right now). ZFS has improved/changed between those 8.2 "versions". I upgraded to 8.2-STABLE last night. (8.2-RELEASE-p3 it calls itself) using freebsd-update. Unfortunately, things are worse. Scrubbed a pool; the system crashed 17 minutes in. Rebooted, let it continue the scrub, crashed 34 minutes in . screenshot from the first crash: http://people.internet2.edu/~danno/zfs/screenshot-8.2-stable-crash.png Still can't dumpon to my mpt device so no crash dump. If it would be useful I can hook up a USB drive to get a dump. Does FreeBSD 9 have further ZFS improvements vs 8.2-STABLE? thanks danno -- Dan Pritts, Sr. Systems Engineer Internet2 office: +1-734-352-4953 | mobile: +1-734-834-7224
