I created it with RAID Z1, but the capacity is less than I expected.

[KuriKuchi]

I am using translation software.
I am new to Proxmox.
Please help!

I bought three WD Red Plus 8TB and built RAID Z1 during Proxmox installation.
However, there is only 6TB available when there should be 16TB available.
In addition, since 3TB is allocated to local-zfs and 3TB to local, I am having trouble using only 3TB in effect.
I would like to be able to use 16TB, but is that the specification of RAID Z1?

what does 'zfs list' and 'df -h' show?

ok thanks, can you also post the output of 'lsblk' and 'zpool status' ?

ok this shows that only 2TiB per disk is used for the zpool... so 4TiB looks right

did you manually change the size in the installer?
