Yeah. I'm getting tons of these on all my machines as well.

sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.cwsys.dataset.objset-0x2c
c
d.zil_itx_metaslab_slog_alloc)!



Yep. Seems to be a real thing just pouring out all over the console here
too :


sysctl_warn_reuse: can't re-use a leaf
(kstat.zfs.t1.dataset.objset-0x4b0.zil_itx_metaslab_slog_alloc)!
This only happens on import: when the system boots and when any pools are
imported later on.


Just a tad uncomfortable to see.
Uncomfortable but harmless.

So tons of the messages like below could be ignored?

sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zhgst.dataset.objset-0x5f6.zil_itx_metaslab_slog_alloc)! sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zhgst.dataset.objset-0x5f6.zil_itx_metaslab_slog_alloc)! sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zhgst.dataset.objset-0x5f6.zil_itx_metaslab_slog_alloc)! sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zvol.dataset.objset-0x66b.zil_itx_metaslab_slog_alloc)! sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zvol.dataset.objset-0x66b.zil_itx_metaslab_slog_alloc)! sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zvol.dataset.objset-0x66b.zil_itx_metaslab_slog_alloc)! sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zvol.dataset.objset-0x54.zil_itx_metaslab_slog_alloc)! sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zvol.dataset.objset-0x54.zil_itx_metaslab_slog_alloc)! sysctl_warn_reuse: can't re-use a leaf (kstat.zfs.zvol.dataset.objset-0x54.zil_itx_metaslab_slog_alloc)!

BTW, thank you for bringing this up.

I haven't looked at this too closely but could dataset_kstats_create() be
called more than once for each dataset?

We should probably also check to verify the leaf nodes are removed when a
pool is exported as well. I don't have any time to test this hypothesis
today but maybe tomorrow sometime.
