Fascinating. This looks like an undocumented change in the way a zpool status is reported. I see the same thing here : $ uname -a SunOS mercury 5.10 Generic_142909-17 sun4u sparc SUNW,Sun-Blade-2500 $ $ zpool status pool: mercury_rpool state: ONLINE status: The pool is formatted using an older on-disk format. The pool can still be used, but some features are unavailable. action: Upgrade the pool using 'zpool upgrade'. Once this is done, the pool will no longer be accessible on older software versions. scrub: resilver completed after 0h0m with 0 errors on Wed Sep 29 17:26:25 2010 config: NAME STATE READ WRITE CKSUM mercury_rpool ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c3t0d0s0 ONLINE 0 0 0 c1t2d0s0 ONLINE 0 0 0 6.74M resilvered See "mirror-0" ? I didn't do that. Too bad the sources for zpool status are not open anymore :-( Dennis
