Package: zfsutils-linux Version: 0.8.3-1 Severity: important Dear Maintainer,
please disable shipped crontab zfs scrub script by default. The current package, significant deviats from the upstream, and is a rather arbitrary decision by the maintainer, not a user or zfs developers. This decision also can negatively impact system performance with multiple pools being scrubbed at the same time, or just affect performance in general, i.e. on laptops when running on battery, or when pool is mounted from device on iSCSI share. I strongly suggest commenting out the crontab entry in the /etc/cron.d/zfsutils-linux for doing this. There is nothing in ZFS requiring to run zfs scrub regularly, and it should be left to the user what to do about it. It is no less safe than any other file system on the planet (in fact even without scrub it is very safe). The current behaviour isn't clearly documented or communicated either (i.e. in package description).
