Thank you for your reply,
Yes we did, once we do the rebalance process, those files already on old bricks will move to new bricks. However, if we write new files to volume, they will still distributed to old bricks, not new.

After expand, you need to run rebalance (at least the fix-layout) to get the files get distributed to newer bricks.

Hello,I have a glusterfs deployment, the version of which is 3.12.2.  When I expanded a volume, I encountered with a problem that new files wrote to volume will not appear on those bricks newly added to the volume. I mean new files will only wrote to original bricks of that volume (bricks before expand). Those new bricks will never used.
I made some test on the latest version of glusterfs, this problem disappeared. However, for stability concerning, I cannot upgrade to new version. I plan to made a patch on the old 3.12.2 glusterfs, just fix this one bug. Would you please tell me some information about it? 

Thank you very much!
