    So now that Ubuntu 19.10 can natively install to ZFS and this is planned to be expanded in 20.04 LTS. How can we online backup our ZFS pools and restore successfully?

  2. Re: FSArchiver LVM restore fails to boot - what did I miss?

    Nope, could not get anything to work. Eventually just started clean and set up most everything over again. Still had the drive image so I could copy config files for a lot of things.
  3. Re: FSArchiver LVM restore fails to boot - what did I miss?

    I have a plan, does this sound like it will work?

    Boot to install CD, install 19.10, boot to new 19.10 to test for good measure. Update if needed.

    Boot to install CD again, copy /boot and...
  4. Re: FSArchiver LVM restore fails to boot - what did I miss?

    Yeah, I did do an initramfs and I checked and saw that it had in fact generated a new image, update-grub would not work but I assumed that was because I was in a quasi in between place and my manual...

    I did exactly the same thing. Works for now but I still don't know its mechanism for returning once deleted either. If you find out let me know!

  8. Re: I think I got hacked by some crypo mining malware

    Kapersky tagged it as HEUR:RiskTool.Linux.BitCoinMiner when I uploaded a TAR of the files they installed. Maybe accurate, maybe just lumps all bitcoin miners together then they see bitcoin mining...
  9. Re: I think I got hacked by some crypo mining malware

    Yeah, no root access. Can't login as root (actually can't SSH as compromised user either) and they clearly did not have password. They had a back door via the authorized_keys but it would do no...

    No BT server on the system. System on a private subnet, not DMZ. No ports open to public. Reaching server requires physical presence on subnet or access via a dual homed server (interface on front...

    Their hamfisted overwrite on cron told me pretty quick because my jobs were not running.

  15. Hurray for Ubuntu 18.04 and hardware accelerated x.265 decoding for Intel graphics

    I have really struggled with this, getting a high bitrate 4K h.265 stream decoded in earlier versions of Ubuntu, looked like it was going to take a machine with either stand alone nVidia card and...
  16. Re: Trouble with 4K playback with VLC on 17.10 with Intel 7th gen i5/Iris 640 gfx

    Actually the way it worked out was abandoning 17.10 and rolling back to 16.04.4. I had several troubles with 17.10, I think Wayland being one of them. Running with the same i5 with stock VLC the...

    Bitrate about 43K, 8 bit h.264.
  19. Re: Trouble with 4K playback with VLC on 17.10 with Intel 7th gen i5/Iris 640 gfx

    Looks like you were right about that, switched to mpv and CPU utilitzation during 4K playback dropped from maxing all four threads to about 60-70% on the threads, not huge but changes play from...
  20. Trouble with 4K playback with VLC on 17.10 with Intel 7th gen i5/Iris 640 gfx

    I assumed that with hardware decoding and all that a 7th gen i5 with Iris 640 graphics was more than enough to handle 4K video playback but it seems not. When I do playback all four threads go to...

    Re: Looking at RAID storage for backup

    Storage is relatively cheap, and drives always fail eventually. RAID (MDADM), as far as storage (not main drive) has been pretty well supported for a long time now. There is no need to resort to...

    I was looking for an alternate solution and I came across one way to do it that simulates a partition. It is a tiny bit kludgey but given that it is on a fault tolerant array it might not be so bad....
