The RAIDZ bit might be significant, if it isn't calculating the overhead properly on old pools for some reason. What were the zpool and FreeBSD versions before/after the upgrade? The output of "zpool history -i storage"/"zdb -h storage" might shed light on any changes. Also try "zdb -bb" - this will go through all block pointers and verify there are no leaks; unfortunately it might take as long as a scrub. :( -- Dylan --=20 Dylan Leigh // VU# s4081906 // www.dylanleigh.net
