Hi Matt Can of worms - should it be opened? Ok, it's not the laptop, it's the desktop. The laptop drive is a spare 1tb drive and I could add several more (laptop drives). I was using 2 x 2tb disks. They are gone now. So I have space/capacity for 4 drives. I can back data up. The desktop is my main computer and I use it daily. I think it is back to the drawing board and maybe leave the can of worms shut for the minute! I'll carry on working as is until I can afford another ssd. That said, when I read the ZFS page, it mapped out my needs exactly: "Ari has a single disk workstation. She buys a new disk and plugs it in. ZFS automatically adds the new disk space into the pool. Her home directory is mirrored, while her OS and temp space is striped automatically in the background." If I wanted to step into this world it seems possible but.... does is it best to have ZFS running on the 240gb drive before moving onto the next drive or can I leave the ssd as is and when ready add another ssd and let ZFS do it's work. You must be despairing of me! I know I challenge you, but I do
want to learn, it is just where do you start? On 11/11/2018 6:44 pm, mr meowski

Or can I backup the laptop drive and then install ZFS on the 1tb. Is there a point where the 240gb drive needs it as well?So, hang on a sec. Your laptop has a 240Gb internal SSD running Ubuntu version unknown _and_ this random external 1Tb drive which is presumably plugged in via a USB adapter? The 1Tb drive has had anything important saved from it and is now free to nuke and use for whatever? I'm hoping that your internal SSD is being backed up anyway but simply installing ZFS - technically, the kernel modules are already included in your kernel, you're just installing the userspace components to interact with them - is 'safe' to do. Well, as safe as running 'apt install $whatever' is normally. This isn't some super sketchy experimental thing that should only be tested in a VM for example. In an _ideal_ world you'd be an experienced Linux ninja, ZFS would be easy to use, there wouldn't be complex licensing incompatibilities between the Solaris bits and Linux resulting in kernel taint and distribution legal hurdles, your laptop would have several redundant NVME drives and a massive ECC RAM cache for ARC and you'd already be running a distro setup to run an encrypted ZFS root filesystem. Unfortunately in the real world absolutely none of those things are true and you'd be mad to even consider running ZFS as your root filesystem on that laptop. ZFS isn't even a good fit for the spare 1Tb drive to be honest - it's just a convenient blank disk to experiment safely with. I kind of feel like we're opening a real can of worms here Mr Brown :] Cheers |
