I'm about to enable compression on my ZFS filesystem, as most of the data I intend to store should be highly compressible.
Before I do so, I'd like to ask a couple of newbie questions.... First - if you were running a ZFS without compression, wrote some files to it, then turned compression on, will those original uncompressed files ever get compressed via some background work, or will they need to be copied in order to compress them? Second- clearly the "du" command shows post-compression size; opensolaris doesn't have a man page for it, but I'm wondering if there's either an option to show "original" size for du, or if there's a suitable replacement I can use which will show me the uncompressed size of a directory full of files? (no, knowing the compression ratio of the whole filesystem and the du size isn't suitable; I'm looking for a straight-up du substitute which would tell me original sizes") Thanks Ross -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
