Small files are stored in small records so we should be fine for that. The recordsize (would be better named max_recordsize) is the size of records (I call them Filesystem blocks) when files gets to be larger than recordsize. Smaller files are stored as single records (in increment of disk sectors). -r _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
