To follow on the subject of VDEV caching, even if only of metadata, in oi_148a, I have found the disabling entry in /etc/system of the LiveUSB:
set zfs:zfs_vdev_cache_size=0 Now that I have the cache turned on and my scrub continues, cache efficiency so far happens to be 75%. Not bad for a feature turned off by default: # kstat -p zfs:0:vdev_cache_stats zfs:0:vdev_cache_stats:class misc zfs:0:vdev_cache_stats:crtime 60.67302806 zfs:0:vdev_cache_stats:delegations 22619 zfs:0:vdev_cache_stats:hits 32989 zfs:0:vdev_cache_stats:misses 10676 zfs:0:vdev_cache_stats:snaptime 39898.161717983 //Jim _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
