[SOLVED] a bit lost with ZFS (closed topic)

[Joris L.]

Recently added an extra NVME drive to the system, using ZFS.

After adding it i'm lost as what is happening. ZFS appears to have 'absorbed' it but i cannot partition it. There appears no way to undo it etc.

I've definitely done something wrong but cannot progress, any pointers ?

We need more informations to help. What is "zpool status" and "lsblk" returning?

This is normal. ZFS can not be used as a clasical disk! But you can create datasets(think like a partion with a File Sistem on it):

zfs create YOUR-POOL-NAME/new-data-set
- example: zfs create rpool/tmp

In any dataset("zfs list" will show what datasets do you have)

In any dataset you can create files/folders like in any other FS.

Also you can create a block-device(think as an empty disk without any partion):

- example:
zfs create -b 16k -V 50331648k rpool/data/vm-2018001-disk-0

Good luck /Bafta !

After more review i think i understand better. Since neither 'zpool status', neither 'lsblk' shows the actual nvme device in any way i assume my attempt at reverting my actions was succesfull. Maybe not yet visible at the time last time i looked.

This means i can actually try and redo my prior actions in more comfortable circumstances.
