Hi,
You need to check the rebalance logs (glu_linux_dr2_oracle-rebalance.log) on glustoretst03.net.dr.dk and glustoretst04.net.dr.dk to see what went wrong.
Regards,
Nithya

Hi
I'm trying to remove 2 bricks from a Distributed-Replicate without losing data. But it fails in rebalance
Any help is appreciated...
What I do:
# gluster volume remove-brick glu_linux_dr2_oracle replica 2 glustoretst03.net.dr.dk:/bricks/brick1/glu_linux_dr2_ oracle glustoretst04.net.dr.dk:/ bricks/brick1/glu_linux_dr2_ oracle start
