You are right, I missed that ret is set to 1 here in the above snippet. @Milos - Can you please provide us the volume info file from /var/lib/glusterd/vols/<volname>/ from all the three nodes to continue the analysis? -Ravi @Pranith, Ravi - Milos was trying to convert a dist (1 X 1) volume to a replicate (1 X 2) using add brick and hit this issue where add-brick failed. The cluster is operating with 3.7.6. Could you help on what scenario this code path can be hit? One straight forward issue I see here is missing err_str in this path. -- ~ Atin (atinm)
