I'm putting together a new desktop using a Samsung SM951 NVMe drive. I |
2 |
booted sysrescd, partitioned the drive and ran |
3 |
|
4 |
mkfs.btrfs /dev/nvme0n1p3 |
5 |
mount /dev/nvme0n1p3 /mnt/custom |
6 |
|
7 |
df -T, mount and findmnt all show this is mounted as a btrfs filesystem, |
8 |
e.g. |
9 |
|
10 |
/dev/nvme0n1p3 on /mnt/custom type btrfs (rw,relatime,ssd,space_cache) |
11 |
|
12 |
I can create files in here but cannot do anything btrfs-y |
13 |
|
14 |
% btrfs filesystem show /mnt/custom |
15 |
ERROR: not a valid btrfs filesystem: /mnt/custom |
16 |
|
17 |
% btrfs subvolume create /mnt/custom/test |
18 |
Create subvolume '/mnt/custom/test' |
19 |
ERROR: cannot create subvolume: Inappropriate ioctl for device |

Google has been no help at all. |
