Erm, that's a curious bit of modern folklore. How the drive was connected previously changes absolutely nothing. The problem here is probably from having dedup enabled. Disabling it does not affect the existing data, which has already been deduplicated. Reading any of this will incur a deduplication table lookup, which can be quite expensive in terms of random seeks (you can check with DTrace, see /opt/DTT/disk/seeksize.d). I've also seen poor performance on a pool that was previously full. -Albert _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
