  1. ZFS Memory requirements

    I wouldn't, Dedup is kind of busted. They are rewriting how it works from a hash table to a log format. Hard links are better for now, (you just got to be aware of them)
  2. Freenas Setup Questions

    Yeah, I'd thing so. Lots of zero space on a disk.
  3. ZFS vs RAID+ZFS

    ZFS will add it's own partition table. no need to partition. Usually I have the OS itself on a mirror and the array separate so I can create it on the command line. (so I can roll back the OS independent of the data. It can be done the other way but.. eh. maybe I want to change systems or something else.) I'm not totally sure the installer will do raid 10 (stripe on mirrors layout) I haven't tried. I believe the installer will let you create the disk manually. Your create command should look like.. (this is just if you wanted to only make the data tank with the OS separate after install do) zpool create tank -n -o ashift=12 -O atime=off -O compression=lz4 -m /mnt/tank mirror ada1 ada2 mirror ada3 ada4 (I use tank because like the creators of ZFS, I also am a fan of the Matrix) so more parity would be. mirror dev dev dev mirror dev dev dev mirror dev dev dev (etc if you wanted that) Those are the datasets the installer makes on default. (so it can apply the best properties to different data) zroot 211G 680G 88K /zroot zroot/ROOT 4.68G 680G 88K none zroot/ROOT/default 4.68G 680G 4.68G / zroot/tmp 100K 680G 100K /tmp zroot/usr 1.19G 680G 88K /usr zroot/usr/home 223M 680G 223M /usr/home zroot/usr/ports 1000M 680G 1000M /usr/ports zroot/usr/src 88K 680G 88K /usr/src zroot/var 964K 680G 88K /var zroot/var/audit 88K 680G 88K /var/audit zroot/var/crash 88K 680G 88K /var/crash zroot/var/log 500K 680G 500K /var/log zroot/var/mail 112K 680G 112K /var/mail zroot/var/tmp 88K 680G 88K /var/tmp It's a nice layout it's why I usually take Auto mode but it can be re-created or ignored and you can do your own thing. I might have to load up a VM and look at what the installer does to help you. I don't use it all that often.
  4. ZFS vs RAID+ZFS

    https://www.freebsd.org/doc/handbook/ You can tag me too if you have issues and need to get my attention up here.
  5. Freenas Setup Questions

    LZ4 is applied to files at the time they are created, if you shut it off, new files won't have it but the old ones will. (I'd recommend setting it and forgetting it) The parent and child are not affected just whatever is in the dataset. (tho parent properties will propagate to the children if unset in the child) So if the entire pool is LZ4 all the children will be unless you set it off. (all ZFS properties work this way) vm.swapiness is for ZoL, ZFS native linux. It does not need to be set on guests. For ZFS send. You can do that. It's a pipe-able command.. so you can get creative with it. Visible snapshots are possible. I just don't remember how to do it.
  6. ZFS vs RAID+ZFS

    Oh.. Great.. just like Sendmail from 1980. I seen that they had ip (and that is a stupid name for configuring network interfaces because not all of them do IP) This new thing is news to me. This is my static network config in FreeBSD. ifconfig_em1="inet 192.168.8.32 netmask 255.255.255.0" One line in rc.conf.. soooo hard and confusing. I don't exactly see the point for servers. You have fast cache, ram, slow cache SDD's and physical, spinning disks. IDK how Optaine fits in there or if we need another layer. I haven't used Live TV on Emby but people say it's fantastic and I wanted to add a device to do it.. (homestar something..)
  7. How to VNC connect to a FreeNAS VM

    Ok, the change may not be too bad however because NAS4Free and FreeNAS are very similar products.. both based on FreeBSD so the disk pool can probably be imported directly. It was just an idea.
  8. How to VNC connect to a FreeNAS VM

    I think NAS4Free might use Virtualbox instead of Bhyve. What off chance where you going to run on Ubuntu? Your app may run native. (you don't need a good reason.. could just be as simple as I wanted ubuntu.)
  9. How to VNC connect to a FreeNAS VM

    Your Ubuntu guest you may be able to connect to via SSH in the meantime. Xen sort of exists, VirtualBox also.. I'm unsure what they are like to get going on FreeNAS tho. I imagine with abit of hacking I could do it. Headless Virtualbox isn't too too bad.
  10. How to VNC connect to a FreeNAS VM

    Ok you may have a bhyve limitation then. Bhyve is only a few years old now and.. for that age its pretty good really but they didn't backport it to work with older processors so you luck may vary. I was actually surprised it could do graphical consoles already at all and not just serial output. it also does PCI passthrough but not for graphics cards (just yet.. its coming) Your Ubuntu guest you may be able to connect to via SSH in the meantime.
  11. How to VNC connect to a FreeNAS VM

    That is for the webui, not the vnc server.
  12. How to VNC connect to a FreeNAS VM

    My understanding of this is the connecting and the vnc server is saying hello > no your bad, goodbye. The log on the server may have some clues as to why. Your at the limit of what I know, try google or FreeNAS forums maybe.
  13. How to VNC connect to a FreeNAS VM

    Mm.. not sure might be a client issue. Try TightVNC.
  14. How to VNC connect to a FreeNAS VM

    Set a test one and try it. It may want something for the auth.
  15. How to VNC connect to a FreeNAS VM

    So it connected and the VNC server denied the connection. That tells us it's up, its listening. My guess is password problem.
