[Gluster-users] Rebalance with old bricks almost full

we have a setup with few bricks which were almost full. We added new
ones and started rebalance process. We are using older version of
Gluster 3.2.7 because we have mixed rdma/tcp setup. When we started the
rebalance there was abouth 25% free space on the old bricks. However,
since the volume is being used constantly we have a situation where old
bricks are near cluster.min-free-disk limit (currently set to 50GB),
while the new one have bunch of disk free (e.g. some old bricks are 100%
used, while new ones are at 65% or 8TB disk free).
Could someone please clarify/advise:
- what will happen if rebalance process tries to push data to a brick
which space is below cluster.min-free-disk limit? will gluster place
this data automagically to one of free bricks? or will the data be lost?
- what is the recommendation in this situation - should I stop the
rebalance and let gluster automatically place files to non-full bricks?
Thanks in advance,
