I tried to experiment with zdb today and I ran (to verify the integrity of
home64 ~ # zdb -sc -eG home
Traversing all blocks to verify metadata checksums and verify nothing
loading vdev 0 of 2, metaslab 3 of 130 ...space_map_load(msp->ms_sm,
msp->ms_tree, SM_ALLOC) == 0 (0x5 == 0x0)
ASSERT at zdb.c:3502:zdb_leak_init_ms()Aborted (core dumped)
It ended with a core dump very quickly.
I started zdb -scL -eG home then to skip verification of space maps. It
still runs. I'll post the outcome as soon as it is completed.
