Storage Space not correct

[fabian3358]

Hello I have the following problem I have installed 2 20 TB HDDs, these are also displayed with 18.9 TB net each. I assigned both HDDs to a pool as VDEV. If I now look at truenas in the GUI, I only see 12 TB free, although HDD 1 must have 18.9 TB and the second also speak twice, where is the error? I don't want to have a mirror or something, just the full memory. the 12 TB for HDD one is correct because I've used up a bit, but still more should be available overall.

Please post the output of zpool status in code brackets. We will be able to tell you what happened from this data. 12TB does seem a little short, do you have data on the pool consuming space? Also post the output of zpool list so we can see where the capacity might be going.

So you want to have a stripe, no protection at all? That would give you the maximum capacity of the two drives combined.
