So I want to remove it. The volume is of distributed type without replica.<br class="">
<br class="">
I use commad: gluster volume remove-brick data server1:/vdata/bricks/data start,<br class="">
It is ok. The command is successfully accepted by gluster. But then I check status: gluster volume remove-brick data server1:/vdata/bricks/data status.<br class="">
IT showd:<br class="">

Node Rebalanced-files size scanned failures skipped status run time in h:m:s<br class="">
