[Gluster-users] volume replace-brick start is not working

[Alessandro Ipe]

Hi,


We have set up a "md1" volume using gluster 3.4.2 over 4 servers configured as distributed and replicated. Then, we upgraded smoohtly to 3.5.3, since it was mentionned that the command "volume replace-brick" is broken on 3.4.x. We added two more peers (after having read that the quota feature neede to be turn off for this command to succeed...).

We have then issued an
gluster volume replace-brick md1 193.190.249.113:/data/glusterfs/md1/brick1 193.190.249.122:/data/glusterfs/md1/brick1 start force
Then I did an 
gluster volume replace-brick md1 193.190.249.113:/data/glusterfs/md1/brick1 
193.190.249.122:/data/glusterfs/md1/brick1 abort
because nothing was happening.

However wheh trying to monitor the previous command by
gluster volume replace-brick md1 193.190.249.113:/data/glusterfs/md1/brick1 193.190.249.122:/data/glusterfs/md1/brick1 status
it outputs
volume replace-brick: failed: Another transaction could be in progress. Please try again after sometime.
and the following lines are written in cli.log

[2015-01-06 12:32:14.602248] I [input.c:36:cli_batch] 0-: Exiting with: -1

What am I doing wrong ?


Many thanks,


Alessandro.
