[17:24] <[diablo]> Good evening #ubuntu-server ..
[17:25] <[diablo]> guys a friend of mine is about to clean install an old server he has. He's going to install 18.04 server...  Is ZFS fully supported please?
[17:26] <[diablo]> for a mirror of two drives ... will hold data, pictures, movies, music etc
[17:26] <[diablo]> not ZFS for the OS

[19:19] <mason> [diablo]: Yeah, that's easy enough to do. Do your installation using up 30G or so of each drive, standard MD-RAID1/LUKS/LVM, and you can have a big partition at the end of each disk for LUKS->ZFS or straight ZFS, mirrored either way.
[19:19] <mason> [diablo]: Something I like to do with LUKS is use two key slots, so I can have one key in the (encrypted) root, say, /etc/keys or something, and one keyslot dedicated to a passphrase I can type should I somehow lose access to the keys.
[19:20] <[diablo]> hi mason sorry I did Google and found it's fully supported
[19:20] <mason> Yep.
[19:20] <[diablo]> :)
[19:20] <[diablo]> for this no encryption will be required
[19:20] <mason> [diablo]: The trick is that the installer doesn't help you with it, so you'll probably end up doing a dual-stage install.
[19:20] <[diablo]> I use ZFS on FreebSD...
[19:20] <[diablo]> so I wanted to embrace it for my mates box..
[19:20] <mason> Good idea.
[19:21] <[diablo]> cheers for replying tho
[19:21] <mason> FreeBSD and Ubuntu are very similar in terms of how they support ZFS, with the caveat that GRUB can't easily deal with all of it without a ton of handholding.
[19:21] <[diablo]> enjoy your weekend
[19:21] <mason> Already on that.
[19:22] <[diablo]> his install for OS is regular EXT4 and LVM...
[19:22] <mason> On MD-RAID1?
[19:22] <[diablo]> just the RAID mirror I wanna put on  ZFS
[19:22] <[diablo]> OS is just 1 x SSD
[19:22] <mason> You're not going to run ZFS on the MD-RAID are you?
[19:22] <mason> ah
[19:22] <[diablo]> no no... the old spinning rust drives will be vaped to ZFS and mirrored
[19:23] <mason> kk
[19:23] <[diablo]> :)
[19:23] <mason> FWIW, I also like using GPT and specifying vdevs using GPT labels. Very, very easy, consistent, trouble-free.
[19:23] <mason> Consistent between FreeBSD and Ubuntu even.
[19:24] <mason> My last gushing recommendation will be thinking about using the Linux EFI stub loader, because then you can do away with GRUB entirely. I keep copies of my kernels and initrds in my ESP and boot Linux directly, no bootloader, with mirrored/native-encrypted (or LUKS for older Ubuntu) ZFS root. Good stuff.
[19:25] <mason> Of course, if you do that you're moving away from what the shipped installer can handle, but, eh.
[19:25] <mason> Anyway, on to the weekend-enjoyment phase. You have a good one too.
[19:35] <[diablo]> mason cheers, I might do that
[19:35] <[diablo]> all the best
[20:55] <ChmEarl> trying to boot `eoan-live-server-amd64.iso` in qemu with kvm.. I get a frozen window and the language menu never appears, while the disco ISO instantly gives this
[20:55] <ChmEarl> using qemu-4.1 on Debian buster
[21:19] <compdoc> do you use virt-manager?
[21:26] <ChmEarl> compdoc, no, I use cmdline
[21:27] <ChmEarl> compdoc, it seems that qemu-4.2 has this fixed with a new kconfig for CONFIG_LZ4

[21:39] <mybalzitch> stupid bugs
[22:00] <ChmEarl> looked over the qemu-4.2* tree and there is nothing new for lz4 in ./configure
[22:01] <ChmEarl> only the u-boot: roms/u-boot/lib/lz4.c
