[PVE-User] Where is ZFS encryption key in Proxmox 7.1

No.  That means that the encryption *feature* is enabled, i.e. you may now proceed to encrypt your dataset... if you really want to find out exactly how that breaks things, I guess.
If it came back as disabled, you would not be able to use encryption at all on that dataset.

Hello Thomas,

I have repeated the following steps:

1 - Went to PVE Node/ ZFS/ Create ZFS/
2 - On the dialogue box name = my_pool, Add Storage (check), Select Devices
(2 x 1TB disks), RAID Level = Mirror, Compression = off, ashift = 12
3 - Hit Create
4 - Open the command line on my pve node and typed:
zpool get feature at encryption my_pool

And I got this as a response:

NAME     PROPERTY            VALUE               SOURCE
my_pool  feature at encryption  enabled             local

Does that mean encryption is enabled?

Thanks again.
