zpool vs zfs size lost in 11.2-U1 vs 11.2-U3.

TL;DR - zpool vs zfs size wildly different. Only can use less than half of capacity of disks (22 TB out of 48TB). Is this expected?

Hi All,

I need some help. I read the following link about the difference in size between zpool and zfs, but I'm not sure this is exactly the same issue.

I have 24, 2 TB drives in two RAID Z3 groups joined to give me about 43 usable terabytes in zpool.

However, on the front page in 11.3-U1 it never displayed correctly and showed:

I never bothered to look much into it, until I upgraded to 11.2-U3 and now it shows:

This caused me concern so I ran a zfs list command and it showed:

Main is the only pool and should be using all the available data. I have read some forum posts that this was a really poor disk layout. I did this to try and make one large mount point as it is almost solely used for sharing video files. Is there a more efficient layout to utilize the space, but still maintain a fairly resilient data protection strategy?

Thanks for all the input!

Were you able to figure this out? The dashboard seems to match your listings.

Would this have anything to do with the change in reporting overall pool capacity to pool storage capacity? which I believe happened in 11.2u3
