...pool ( only for pool, not filesystems ) and it helps. Now space maps, intent log, spa history are compressed. Not I''m thinking about disabling checksums. All metadata are written in 2 copies, so when I have compression=on do I need checksums ? Does zfs will try to read second block when zio_decompress_data will return error ? Is there other way to check space map compression ratio ? Now I''m using "#zdb -bb pool" but it takes hours. This message posted from opensolaris.org
