 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 |
| Enzime | the simplest fix would be to add canmount = "off" and mountpoint = "none"; to rootFsOptions | 04:13:47 |
| lanice | Thank you, will try that! Is it possible to make those changes without reinstalling just with disko, or do I need to wipe and repartition everything? | 04:22:06 |
| Enzime | the simplest solution would be running zfs set -u canmount=off mountpoint=none data and then rebooting | 04:29:20 |
| lanice | Right, makes sense, thank you! | 04:33:40 |

| guiniol | So. I wanted to create a couple of extra datasets in an existing ZFS pool without wiping everything. Is there a way to either get disko to not remove existing data (is this what the mount mode does? I couldn't find much about it in the docs) or to get disko to give me the commands it would run to create those datasets (which I would the run myself). | 21:05:48 |
