Hi Victor; thank you for your answer. I tried with -S with no luck. I tried also different levels of verboseness (-vv/-SS, etc). E.g., $ zdb -S all:all tank/test Dataset tank/test [ZPL], ID 197, cr_txg 94447, 63.5K, 7 objects $ >From what I've read there's also zdb -bbbb <pool> which outputs ckalg as a side effect while doing some validation checks. E.g., objset 0 object 26 offset 0x76000 [L0 SPA space map] 1000L/c00P DVA[0]=<0:232c680400:c00> DVA[1]=<0:108f12a00:c00> DVA[2]=<0:430237ce00:c00> fletcher4 lzjb LE contiguous birth=34121 fill=1 cksum=911bd91bf9:fdcdafd76e06:1056870d1b78c0a:c623a15a8f99054a Just wondering if is doable on a per user specified block basis.
