[Gluster-users] gluster volume rebalance making things more unbalanced
Sadly I have no idea why rebalance did that , so you should check the logs on all nodes for clues. Is there any reason why you used "force" in that command ? Best Regards, Strahil Nikolov ? ?????????, 27 ?????? 2020 ?., 17:32:24 ???????+3, Pat Haley <phaley at mit.edu> ??????: Hi, We have distributed gluster volume spread across 4 bricks.? Yesterday I noticed that the remaining space was uneven (about 2.7TB, 1.7TB, 1TB, 1TB) so I issued the following rebalance command ???? ????* gluster volume rebalance <VOLNAME> start force ???? Today I see that instead, things have gotten even more unbalanced (64G 853G 6.2T 20K).? I'm killing the rebalance now.? What should I do to make sure that I get a successful rebalance?

Hi Strahil The documentation I looked at: * https://docs.google.com/document/d/18iGX6I7I0yHUZ1zAfLIEnXDRPkIoMh6CHmwyyb6J4GM/edit#heading=h.oogvisuwd2qd suggested that not using force might leave some links behind that could affect performance Thanks Pat On 8/27/20 10:43 AM, Strahil Nikolov wrote:> Sadly I have no idea why rebalance did that , so you should check the logs on all nodes for clues. > > Is there any reason why you used "force" in that command ? > > > Best Regards, > Strahil Nikolov > > > > > > > ? ?????????, 27 ?????? 2020 ?., 17:32:24 ???????+3, Pat Haley <phaley at mit.edu> ??????: > > > > > > > > > > > Hi, > > We have distributed gluster volume spread across 4 bricks.?

[Gluster-users] gluster volume rebalance making things more unbalanced
Hi Pat, I checked?https://docs.gluster.org/en/latest/Administrator%20Guide/Managing%20Volumes/#rebalancing-volumes and indeed that is possible to affect your performance. What is your current status ? Did you run a new rebalance ?
