There was a thread late last year on the developer list that described similar symptoms: http://lists.open-zfs.org/pipermail/developer/2014-October/000887.html Have you by any chance done zfs recv into this filesystem, and then further have the async_destroy feature enabled? If so, you could possibly be hitting this issue. zdb -bb on the pool would show an increasing amount of deferred frees over time. I see from a more recent message you're running a rather ancient kernel, so you might not even have this feature. But it feels like we are in the throw darts at the wall stage of problem solving ATM, so here you go :), good luck. _______________________________________________ OmniOS-discuss mailing list [email protected] http://lists.omniti.com/mailman/listinfo/omnios-discuss
