  • If the drives added to the pool need to be formatted, is there a possibility that it wipes the data on it?

    that’s what I meant, yes, but you said you have 2 16 TB drives right? at least with ZFS, setting up a mirror can be done only starting with a single drive. It’s a godsend.

    first, you take the empty drive, check that it’s actually empty, and if so, create a ZFS pool of a single drive from it, with zpool create. copy all your data over. you can use rsync, it has a bunch of options for preserving most filesystem metadata, and for printing progress.

    when done, check that absolutely everything got transferred, and add the other 16 TB drive too to the pool with zpool attach. doing this will convert the pool with only a disk vdev, into a pool with a mirror vdev of 2 disks.

    further recommended reading: https://openzfs.github.io/openzfs-docs/man/master/8/zpool.8.html

    you may want to enable compression from the beginning. if you do it later, existing data won’t be compressed. media files mostly don’t benefit from this. compression is enabled on the dataset level, with the zfs command, if you set it to lz4 (recommended alg) for the root dataset, everything will be compressed that way.







  • People who’ve written doctoral theses on machine learning and and natural language processing have asked me for help building their gaming rig.

    I think that could still be different. knowing the internals of the computer is different from knowing which brand to buy, how to combine, compatibility, drivers, etc








  • Even people that are very low information on technology, know that the Internet is a source of potential surveillance, and having your info on the internet in any form is a potential for being surveilled. Everybody knows that all the big IT companies are trying to gather as much information as they can. And Amazon is right at the top among them.
    So to claim they were ignorant of Amazon possibly collecting and sharing their data is a bit far fetched IMO.

    you are largely overestimating the capabilities of the average consumer. most don’t even know on a surface level how the internet works, and what dangers it poses.


  • encryption wouldn’t solve the problem, just raise more questions. how is it encrypted, with what algorithm? was the alg implemented securely? who has the decryption keys? how were the keys generated? were they generated from a good enough entropy source? these are non-trivial questions that have to be asked in an encrypted system where encryption is not just a gimmick or a marketing buzzword.

    having encryption and “secure!” plastered all over the box and the phone app does not mean anything, especially when you need protection against the manufacturer.
