 Enzime | people make the empty snapshot for impermanence setups where you wipe your rootfs on every boot | 02:38:54 |
 lanice | Ah, right, I've seen that before. That makes sense, thank you! Not doing that for now. | 03:00:51 |
| lanice | For my HDD's, I have a zpool "data" configured like this:
data = {
type = "zpool";
mode = {
topology = {
type = "topology";
vdev = [ { members = ["hdd24tb_0" "hdd24tb_1" "hdd24tb_2"]; mode = "raidz1"; } ];
};
};
rootFsOptions = {
atime = "off";
xattr = "sa";
compression = "zstd";
};
options.ashift = "12";
datasets = {
"data" = { type = "zfs_fs"; mountpoint = "/data"; };
"media" = { type = "zfs_fs"; mountpoint = "/data/media"; };
"backup" = { type = "zfs_fs"; mountpoint = "/data/backup"; };
};
};
After finishing the install with nixos-anywhere, when I do zfs list, the output for that pool is:
data 1.41M 43.5T 139K /data
data/backup 128K 43.5T 128K /data/backup
data/data 139K 43.5T 139K /data
data/media 128K 43.5T 128K /data/media
What confuses me is the double-use of mountpoint /data. It seems both data and data/data is mounted on /data. Why did that happen? I probably did something wrong in my disko config, I'm doing a lot of trial and error and looking at other configs. | 03:21:46 |

| lanice | Could it be that I should not declare the first of those datasets at all, "data" with mountpoint "/data"? | 03:34:28 |
| Enzime | it looks like the dataset shouldn't be mounted from what you posted, maybe it's something to do with ZFS topologies, I'm not very familiar with them (possibly a bug?) | 04:12:42 |
