Re: Conv distr-repl 2 to repl 3 arb 1 now 2 of 6 arb bricks won't get healed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Meanwhile I tried reset-brick on one of the failing arbiters on node2, but with same results. The behaviour is reproducible, arbiter stays empty.


node0: 192.168.0.40

node1: 192.168.0.41

node3: 192.168.0.80

The brick dir on the faulty arb-volumes does contain ".glusterfs", however it has only very few entries. Other than that "brick" is empty.
