[Gluster-users] (3.1.5-1) "Another operation is in progress, please retry after some time"

[Tomoaki Sato]

Hi,

baz-X-private and baz-Y-private, 2 newly probed peers, have issued the each 'gluster volume add-brick baz baz-{X|Y}-private:/mnt/brick' in very short period. 
Both the 'add-brick's have returned without "Add Brick successful" messages.
After that, 'add-brick' returns with "Another operation is in progress, please retry after some time"  on the both peers every time.
How should I clear this situation ?

Best,

tomo
