I'm curious as to why you use da?p1 as the freebsd-zfs partitions. Where does the freebsd-boot partition reside? da?p2? What does the "gpart show" command tell you? I normally use *p1 for freebsd-boot, *p2 for freebsd-swap and *p3 for freebsd-swap. I know some people who put freebsd-zfs on *p2 and freebsd-swap on *p3. Maybe the partitions are interchangeable after all. As a general rule, I think it's wise to always update the boot blocks whenever you plan to upgrade the pool format or the filesystems. If I have the time later this afternoon, or maybe tomorrow, I will attempt the following on a couple of VMs: 1. Install 8.4-RELEASE with ZFS SPA v28. 2. Upgrade ZFS SPA to v5000. Updating the boot blocks shouldn't be necessary this time. 3. Upgrade by source to 8.4-STABLE and see what happens then. 4. Upgrade by source to 9.2-BETA2, and possibly update the boot blocks using the installed files prior to rebooting, and see what happens then. A second attempt would involve going straight from 8.4-RELEASE to 9.2-BETA2. I'll let you know how well I fared. -- +-------------------------------+------------------------------------+ | Vennlig hilsen, | Best regards, | | Trond Endrestøl, | Trond Endrestøl, | | IT-ansvarlig, | System administrator, | | Fagskolen Innlandet, | Gjøvik Technical College, Norway, | | tlf. mob. 952 62 567, | Cellular...: +47 952 62 567, | | sentralbord 61 14 54 00. | Switchboard: +47 61 14 54 00. | +-------------------------------+------------------------------------+home | help
