>Description:
I read the post about deduplication at
http://blogs.sun.com/erickustarz/entry/how_dedupalicious_is_your_pool which
comes with a sample zdb(8) invocation which fails on FreeBSD 7.2
>How-To-Repeat:
root@coyote:~# zdb -L -S user:all tank | tee /tmp/tank_out.txt
Assertion failed: (��), function rwlp->rw_count == 0, file /usr/src/cddl/lib/libzpool/../../../cddl/contrib/opensolaris/lib/libzpool/common/kernel.c, line 195.
Abort (core dumped)
Exit 134
Fiddling with simple options like -u makes it core dump, too.
Someone should try this on 8-CURRENT to figure out if this is a MFC artefact.
