Hi Petr,
what was the server version before upgrading to 7.2?
Can you please share the shared-brick-count values from brick volfiles from all the nodes?
grep shared-brick-count /var/lib/glusterd/vols/<volume_name>/*

Hi everyone,
we've been running a replicated volume for a while, with three ~1 TB
bricks. Recently we've added three more same-sized bricks, making it a
2 x 3 distributed replicated volume. However, even after rebalance,
the `df` command on a client shows the correct used/size percentage,
but wrong absolute sizes. The size still shows up as ~1 TB while in
reality it should be around 2 TB, and both "used" and "available"
reported sizes are about half of what they should be. The clients were
an old version (5.5), but even after upgrade to 7.2 and remount, the
reported sizes are still wrong. There are no heal entries. What can I
do to fix this?

Let me know if there's any other info I can provide about our setup.
