According to the man-page, I think it should be possible to run zdb -Lbb[s] on a dataset?
zdb — display ZFS storage pool debugging and consistency information
zdb [-AbcdDFGhikLMNPsvXYy] [-e [-V] [-p path]…] [-I inflight I/Os] [-o var=value]… [-t txg] [-U cache] [-x dumpdir]
[poolname[/dataset | objset ID]] [object|range…]
I can run
zdb -Lbbbs tank and get the output.
I would like to do this per dataset if possible, but when I run
zdb -Lbbbs tank/dataset it only outputs 1 line without the blocksize histogram.
is it possible at all?
