Thanks for the congratulations Joe 😊 Very kind of you.

Glad you're here! My Ubu Mate 19.04 just self-borked 2 hours ago (a number of files wouldn't load and work for some reason?), which is fine because it gave me a reason to install 19.10. I decided to try ZFS from my experience with Sun long ago. Now to see how it works?

So far file copies from USB to my SSD is HUGELY faster! I have 2 SSD's in my system and saved my Thunderbird email to sda2. It's 11.6 gigs of files. With EXT4 copying the files back to sda1 was slow and plodding. With ZFS it only took a number of seconds.

I have found that your bash scripts are most useful as training aids. I don't use most of your scripts as-is, but rather study them, find out what you are doing and how you do it, and then either modify one of yours or write my own using yours as a guide. Thanks for posting them.

The fact that ZFS is so complicated to set up and use, in addition to the possible complexity of the normal tasks you use your system for, is one of the reasons that ZFS hasn't been implemented yet on projects like OpenBSD. I think ZFS's complexity and overhead are the stimulus for projects like DragonflyBSD's Hammer and Btrfs in the Linux world.

Finally Canonical with other file system for the Ubuntu.
Red Hat betting in XFS and Suse in BTRFS, finally Ubuntu with ZFS.

Thanks for the BU script, Joe. I use it often to back up my home directory, along with Timeshift to back up Mint. I kinda wish BU would do rolling backups, but that's ok, I simply rename my BU_Backups folder weekly or monthly and re-run the script and that does the trick.

Will update the SolusOS version with these changes on my github as soon as I get a chance.

Great “stupid user” content and very welcoming to boot. I’m afraid I am hooked now. Thanks!
Tried Mint and Abuntu just for a few weeks a year ago but found I missed it. I reinstalled a week ago. How can it seem like an old friend to such a newbie?

I was just thinking yesterday "I have not heard from Mr. Joe in a long time (video-wise!) lately"


Hey Joe! When are you going to update the Wallpapers section? cause I have all of them currently on your server.

[steshaw]

It'd be good to get your spin on NixOS. I find it both pleasure and pain. It has excellent facilities for rollback and boot into previous configurations. I've got it installed on my desktop with ZFS, but that did require quite a bit of command-line work when I did it when installing the previous version.

Joe I really enjoy up and bu saved my butt many times. I recently did a distro upgrade on mate and it trashed my system tried to restore it with cya no help there.

[WrinkledHound]

I've been using zfs since freebsd 7.1 on a server that I've since changed to ubuntu with zfs back at 16 LTS and now on 18 LTS. That must be about 10 years now and I have never had even the slightest problem with zfs. So, it sounds like an update overwrote or cleared something. But, keep in mind that I use zfs only on storage disks and not for the os itself.
BTW, my zpools survived the change from FreeBSD to Ubuntu without any data loss or other problem, as well as fresh install Ubuntu 18 from Ubuntu 16.

[DAVIDGREGORYKERR]

If you want to try ZFS then maybe TrueOS or the latest version of GhostBSD is the way to go as it uses ZFS by default.

and in other unrelated news. privacy is at stake again. startpage the privacy protecting search engine has been sold to... wait for it, a advertising company!... and there goes the data

I just downloaded the new version and tried it out. It makes the backup fine but I am not getting the file that you mentioned. I deleted the old version and rebooted before making the backup. I have the script in my user bin directory and I'm using Mint 19.2 . Thanks for all that you have done .

That issue where you get the Ubuntu to forget all the changes every boot happens if you've installed zsys.

Don't install zsys and it should be fine.
At least that's what my tests show and I've moved all my machines to ZFS.

The ZFS config that Ubuntu uses has actually been used for years by the ppl who used to install it themselves so it's not really that experimental at all.

[motoryzen]

Not that it could be a deal breaker for me, but I wonder if the same historical fact about ZFS needing 8GB's of ram or more to be...practical still applies here for an Ubuntu 19.10 system with zfs as the default file system for those who are still rocking 4GB's of ram on their older rigs running some reasonably modern distros?

[adamsinger]

SolusOS version is up on my github now if you are using solus.

[jwkmpli]

hi joe i have seen those artifacts on boot sometimes the screen hasa full purple color other times the top third is purple and the other 2/3's is grey with a horizontal line of dots , can't remember when this started but its was at least 6mths

¿Ya aprendiste a decir Mate o seguís diciendo Matéi?
