Hello!
I have issues of understanding, why I have a certain amount of allocated storage on my volume. I have a volume over two 3 TB disks in a mirror configuration.
My volume is called "v1" and contains a few datasets. I do not store data in the root of the volume directly. See "vol.PNG" for a picture of the configuration. I actually use 500 GB of that volume with data within the datasets. I have basically no snapshots at the moment. However, I fail to see, why significantly more than 500 GB are occupied on v1.
When I look for occupied space on my drive, I get this (extracted only data about v1):
Do you have an idea, where this space is occupied? I am concerned about the "usedbydataset" property of v1, as there should be no data unique to this dataset. The data is all contained in the datasets within v1.
This is the output uf "zpool list": There is another volume v0 which is just a single disk.
Thank you for any advice,
Adrian

Do you have an idea, where this space is occupied? I am concerned about the "usedbydataset" property of v1, as there should be no data unique to this dataset. The data is all contained in the datasets within v1.
This is the output uf "zpool list": There is another volume v0 which is just a single disk.
Code:
