add new node and expand volume

[wqy0812]

I use glusterfs 3.12.6
I add some nodes to my cluster, and expand a volume, and rebalance data
the volume have 3 bricks（replicate） on old nodes, after volume expand ,3 bricks added to new nodes
the client mount the volume before I add nodes to cluster
mount : mount -t glusterfs node:volumename /dir

then I write data to the volume,and find that the data only write to the bricks on old nodes,even after rebalance,even the brick is full
until I remount the volume

I think remount is unnecessary
is glusterfs‘s bug？or I should update version？

Yes, your expectation is right.

is glusterfs‘s bug？or I should update version？

It could be a bug. Upgrading to latest (near latest) releases always help.

But please note that, if you are writing to same file which was present, then even if you do rebalance it wouldn't help. Did you notice any errors, or concerning logs in rebalance logs (or even in 'rebalance status' command)?

I'm not keep writing files. I did a test:
process:
dd if=/dev/zero of=test bs=1M count=xxxx
expand cluster
expand volume
rebalance volume
dd if=/dev/zero of=test bs=1M count=xxxx

then found that new bricks have no data even the old bricks is full
I haven't tried the new version yet
