[Gluster-users] Clients are unable to connect while rebalancing

[Davy Croonen]

Hi all,

We have a 4 node distributed/replicated setup (2 x 2) with gluster version 3.6.4.

Yesterday one node went down due to a power failure, as expected everything kept working well. But after we brought up the failed node again gluster started, also as expected, its self-healing process. The moment that happens all our client connections to the gluster cluster start freezing one by one till the moment the healing process finishes.

After some research we found this page http://www.gluster.org/community/documentation/index.php/Documenting_the_undocumented with some possible performance options to tweak, performance.least-prio-threads and performance.least-rate-limit. Does anybody has experience with tweaking these options? What are there default settings? Are these the right options to tweak or do we needs another approach regarding our problem?

Thanks in advance.

Kind regards
Davy
