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

[krish]

  Hi Tomoaki,

Issuing peer related commands like 'peer probe' and 'peer detach' 
concurrently with volume operations
can cause the 'cluster' to get into an undefined state. We are working 
on getting glusterd cluster to handle concurrent commands robustly. See 
http://bugs.gluster.com/show_bug.cgi?id=3320 for updates on this issue.

thanks,
kp
