 snowflake | can i reinstall nixos directly from already installed nixos? | 20:21:59 |
| snowflake | i tried but it failed | 20:22:14 |
 hexa | no, you cannot repartition/reformat your root disk while partitions are mounted | 20:22:50 |
| snowflake | also would like to re-import my my already existing config files | 20:23:05 |
| snowflake | ohh i just realized thats why you should do it from a usb flash drive :OO | 20:23:39 |
| snowflake | tysm for making me realize that | 20:23:47 |
| snowflake | whats the easiest method to re-import my configuration files & disko config then? | 20:25:32 |
| snowflake | using a 2nd flash drive? | 20:26:12 |
| snowflake | i guess that would work | 20:26:24 |
| snowflake | or wait i can access my files from the ssd directly from the nixos usb flash installation | 20:27:33 |
| snowflake | gonna try that rn | 20:27:55 |

 Crony Akatsuki | what are the benefits of zfs over btrfs? I'm curious because for me btrfs with subvolumes and compression just works for my needs | 08:20:35 |
 magic_rb | Zfs is actually stable and doesnt randomly fail. Btrfs has a track record of randomly keeling over. Though to be fair, its gotten better and its mostly related to using any of the fancy features of btrfs. Like raid0/1/5/6. Still, zfs is more trustworthy and get more active development. On nixos the fact that its out of tree plays no role as its trivial to install | 08:39:31 |
| magic_rb | I would recommend you go with zfs. I know people that consider data gone if its not on zfs | 08:40:23 |
| Crony Akatsuki | I have used btrfs for over 5 years now, with an arch installation for 3 years and btrfs never gave me any issues with just subvolumes and compression enabled. I haven't tried to do any raid/mirroring so yeah | 08:40:39 |
| Crony Akatsuki | Tho I did consider doing zfs when I make my nas in the future | 08:41:25 |
| magic_rb | Definitely go for zfs if you use any raid features, those are just not stable on btrfs. But then once you do, there is no reason to use btrfs anymore.... in my mind its better to have everything formatted uniformly, easier to manage | 08:42:37 |
| Crony Akatsuki | well the nas would be on a separate device, my desktop is just fine with btrfs. Tho does zfs support features like subvolumes and compression like btrfs? | 08:43:38 |
| magic_rb | Yes | 08:43:57 |
| Crony Akatsuki | and once I do go for zfs, will contact you to help me get started, seems like you know your stuff | 08:44:01 |
| magic_rb | Btrfs is a reimplementation of zfs | 08:44:09 |
| magic_rb | It supports more than btrfs | 08:44:17 |
| magic_rb | Bear with me here, thing is, if you have zfs everywhere you dont have to context switch and once you start using some of the fancier features of it like zfs send/recv, encryption, raid or zvols, it makes sense to have everywhere... but you do you ofc | 08:45:33 |
| magic_rb | Ofc, message away | 08:45:41 |
| Crony Akatsuki | for me a filesystem ( atleast for now ) is just there to keep my files, I don't do anything fancy with it. Tho that will prob change in the future but has been this way for the past 7 years | 08:46:43 |
| magic_rb | Give it time :p | 08:47:26 |
| Crony Akatsuki | I just use restic to backup my important files to a separate btrfs 128gb drive ( my backups are like 2gb ) and backblaze b2 bucket | 08:48:15 |
| magic_rb | Tbh same, im planning to look into a more zfs native solution, but for now havent | 08:48:55 |
| Crony Akatsuki | I might go ahead and reformat my backup drive and my games drive with zfs to test it out, and then move my main nvme to zfs also slowly | 08:49:37 |
| Crony Akatsuki | I do think my vps's just use ext4 with lvm | 08:49:59 |
