I am looking at a APC Power-Saving Back-UPS ES 8 Outlet 700VA 230V AS 3112http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BE700G-AZtotal_watts=200tab=features, I don't know about that model; it makes no mention of shutdown alert / control at all, only 'some models' have a USB connector, and I couldn't find the manual for it there. Certainly not all 'desktop' UPSes support what's needed to communicate and shutdown cleanly, so check carefully both the specs and that software (apcupsd or nut) supports the model. I gather from your timestamp (and that model) that you may be in Australia, in which case you could browse from here for the APCs: http://www.apc.com/products/category.cfm?id=13ISOCountryCode=au [However that page currently throws errors on the various model links of 'Element CACHE.APCTOSECOUNTRYMAPPINGS is undefined in APPLICATION.' :( ] anyone know if apcupsd daemon works fine under FreeBSD or should I be looking at Network UPS Tools (NUT). I'm sure there are people here who can advise. I've only setup Eaton and PowerWare UPSes, and those on a Debian linux server, using NUT. cheers, Ian ___ 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

Is it possible to suspend to disk with geli+Root on ZFS installation
Hi all, Is it possible to suspend to disk (hibernate) when using geli for full disk encryption. My set-up is listed below. So I am going to have an encrypted container and ZFS on top. There are two options for the swap with this set-up, either use a swap file on the ZFS pool or use a separate partition for swap and encrypt that. What I want to know is will either of this work with suspend to disk. Reading geli(8) http://man.freebsd.org/geli/8 man page does not say anything about suspending to disk. Geli itself has suspend and resume commands but looks like they cannot be used on the file system where geliutility is stored (so the root pool cannot be suspended?) And the onetime option does not support geli suspend. Thank you. Yudi PS.

Root on zfs (stable9) - how to make it bootable
Hi, I want to install freebsd9 (stable) on zfs root, unfortunately my bios is unable to recognize GPT discs. I'm using MBR disc, with BSD slice (on mbr index 4) containing freebsd-zfs filesystem. I've no idea how to make it bootable, I've tried using: zpool export sys dd if=/boot/zfsboot of=/dev/ada0s4 count=1 dd if=/boot/zfsboot of=/dev/ada0s4a skip=1 seek=1024 zpool import sys When I select F4 (slice with zfs) whilst booting the computer just turns off. How do I make it boot? Do I need freebsd-boot slice? I have set bootfs property on pool, and added vfs.root.mountfrom to loader.conf.

Root on ZFS
I am following this wiki page to move to zfs root: http://wiki.freebsd.org/ZFSOnRoot I got to this section: Create bootdir directory where the boot file system will be mounted: # mkdir /tank/bootdir # ln -s bootdir/boot /tank/boot I am confused about the symlink line - what is 'bootdir' ?

Yes, I am on 8-RELEASE. I was really looking to create a 3-disk raidz or raidz2 volume with 1 hot spare. I happened across this page: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ2 and started to follow that. Currently live on two slices at arpnetworks.com with that. The trickiest part is that Arp installs an existing system on the disk, and the instructions there don't tell how to remove it. :( I can't remember the workaround, but someone in IRC told me. (gpart destroy didn't work, because it said already in use) I ran into this and figured out I need to remove each slice first. But it did take a little head scratching. I installed a minimal OS from a USB stick onto a single SATA drive. After testing it was installed and running OK, I rebooted and chose the fixit option from sysinstall and followed the above guide. I've got to this part: 7. 'Create ZFS Pool zroot' Fixit# mkdir /boot/zfs Fixit# zpool create zroot raidz2 /dev/gpt/disk0 /dev/gpt/disk1 /dev/gpt/disk2 Fixit# zpool set bootfs=zroot zroot The zpool create command fails because I don't have '/dev/gpt' - I take it I haven't actually installed with gpt in the first place? Can I go back and do that and what's the advantage of gpt? Finally, I had problems with the SAS card in this box, which is a bog standard LSI SAS8041E. I can install OK, but on rebooting it can't find the root slice, panics and drops me into mountroot. Where I get stuck. Any help much appreciated, Matt. ___ 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
