Data is compressed files between 300KB and 2,000KB. This is in AD environment with 20+ servers, all running under a single AD account. So the Opensolaris server sees one owner. We have also 3 or 4 idmap group mappings. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
