Hello Ozgur,
Thanks for the reply.
If i up to etcd size from 2 to 8 GB it's make much problem but if defrag is
fix the "no space" issue can you share your experience? By example is it
spent too much rss etc. and are you doing that with cronjob or manuel. As i
know if etcd went to error with "no space" defrag methot also doesn't work.
Have a nice day.
