Bumping the reported patchlevel isn't considered important enough to warrant building a new kernel. That there's no kernel changes doesn't mean that uname -a info is not updated. You are incorrect. The output of uname -a is taken from the kernel and cannot be updated without installing a new kernel. The good news is that FreeBSD 10 will ship with a new utility called freebsd-version which will provide a better way of identifying if your system is up to date. From the commit message: Introduce the /libexec/freebsd-version script, which is intended to be used by auditing tools to determine the userland patch level when it differs from what `uname -r` reports. This can happen when the system is kept up-to-date using freebsd-update and the last SA did not touch the kernel, or when a new kernel has been installed but the system has not yet rebooted. http://svnweb.freebsd.org/base/head/bin/freebsd-version/ By the way, it will be /bin/freebsd-version as it has been relocated since the import into head. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
4K vs 512byte sector drives on Seagate Constellation E.2
Hi, I've a Seagate constellation ES.2 which supports 4K sectors but diskinfo shows it as 512bytes; da0 512 3000592982016 5860533168 0 0 364801 255 63 I understand that Seagate ships these drives to be compatible with 512byte sectors so that older Windows OSs work on the. But I'm unsure how to get this drive to report as having 4K sectors. I'm really asking from a ZFS perspective as my vdevs show with an ashift of 9 via the zdb command. I'd rather forgo the gnop hack as I prefer a cleaner approach. Any info or insight would be greatly appreciated. - aurf ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: Geli and ZFS

I will be using couple of 3TB HDDs mirrored for data and want to encrypt them. IIRC, there is/was a major performance-difference on Solaris between using ZFS on a partition, or a whole disk. FreeBSD is happy with either. The two alternatives you mentioned were: ZFS over GELI over disk and ZFS over GELI over ZFS over disk While ZFS wouldn't get the raw disk in setup #1, the left-most ZFS wouldn't get it in the second scenario either. I am hoping someone with an in-depth understanding of ZFS will be able to offer some insight. What I usually do and recommend is using GPT with labels for the partitions you'll put GELI/ZFS on. There's a couple of different reasons for this: * It'll let you create your zpool on /dev/gpt/label, which will make it easy to find even when the device moves (harddisk-renumbering, changes from internal ATA to USB enclosure… ) * You don't run things through ZFS twice. * The disk is fully encrypted. * etc Terje signature.asc Description: Message signed with OpenPGP using GPGMail

The $55 Formula
Last week, I had a really good, heart to heart talk with a lady that had been struggling in her business for a while. She had not made any money, people were not getting back to her, and she was ready to give up on the whole thing. I asked her if she was treating it like a job or a hobby??? She immediately said, she was treating it like a job, we both discovered that she was putting in a solid 15-20 minutes a day. She was doing a bunch of little things that didn't produce income for about 2-3 hours. She was not really doing anything that brought in NEW prospects. In her mind, she was working her business for 2-3 hours a day. She was truly hitting the phones for about 15-20 minutes a day and that was it. Even then, if we subtracted the dial time, waiting on the line, voicemails, etc... she was really only FULLY prospecting 5-7 minutes a day. I wanted to show her our opportinity formula in Xplocial it blew her mind, she immediately joined in the next few days she saw a major jump in her Xplocial business.
