I had a zpool with 4x8TB SATA drives in a RAIDz2 with a total capacity of 16TB. I updates to PVE 9 and ZFS to 2.3 and attached 2 additional drives to the zpool using:
I waited after each drive addition for re-silvering and scrub. However, the addition of each drive only added 4TB of new space resulting in a total capacity of 24TB instead of the 32TB I was expecting. I tried to resolve this using the following steps:
However, the resulting zpool is still showing only 24TB of total capacity. I came across a ZFS re-balancing script which just re-writes each file but zfs 2.3+ has a
I only did this for a few files but it it does not seem to be making a difference.
Does anyone have any insight into why I can't see the expected 32TB capacity and how to mitigate this?
