We finally flipped the switch on one of our ZFS-based servers, with approximately 1TB of 2.8TB (3 stripes of 950MB or so, each of which is a RAID5 volume on the adaptec card). We have snapshots every 4 hours for the first few days. If you add up the snapshot references it appears somewhat high versus daily use (mostly mail boxes, spam, etc changing), but say an aggregate of no more than 400+MB a day.
However, zfs list shows our daily pool as a whole, and per day we are growing by .01TB, or more specifically 80GB a day. That's a far cry different than the 400MB we can account for. Is it possible that metadata/ditto blocks, or the like is trully growing that rapidly. By our calculations, we will triple our disk space (sitting still) in 6 months and use up the remaining 1.7TB. Of course, this is only with 2-3 days of churn, but its an alarming rate where before on the NetApp we didn't see anything close to this rate. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
