If it says encryption is on then the admin might think the data is safe, but if it says it is off that isn't the truth either because some of it maybe still encrypted. From a user interface perspective, I'd expect something like Encryption: Being enabled, 75% complete or Encryption: Being disabled, 25% complete, about 2h23m remaining and if we are still writing to the file systems at that time ? Maybe this really does need to be done with the file system locked. I'm not sure how you'd map this into a property (or several), but it seems like on/off ought to be paired with transitioning to on/transitioning to off for any changes which aren't instantaneous. Agreed, and checksum and compression would have the same issue if there was a mechanism to rewrite with the new checksums or compression settings. -- Darren J Moffat ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Having this available to laptop owners seems to me to be important to making zfs even more attractive. I'm not arguing against that. I was just saying that *if* this was useful to you (and you were happy with the dubious resilience/performance benefits) you can already create mirrors/raidz on a single disk by using partitions as building blocks. There's no need to implement the proposal to gain that. Am I correct in assuming that having say 2 copies of your documents filesystem means should silent data corruption occur, your data can be reconstructed. So that you can leave your os and base applications with 1 copy, but your important data can be protected.
