Steps to Reproduce: =================== 1) Create a distrbuted-replicate volume and start it. 2) cifs mount the volume on multiple clients. 3) From client-1 -> start creating files and from a diff terminal start continuous lookups. wait for some time and from client-2 -> Start creating hardlinks 4) Remove few bricks and wait till the remove-brick operation completes. After completion of remove-brick, check rebalance logs and you will see above timer error messages. Actual results: =============== Seeing timer errors in rebalance logs. Expected results: ================= No timer error messages should come in rebalance logs.
On glusterfs version 3.12.2-7.el7rhgs.x86_64, followed the same steps as in the description and didn't see these timer errors in rebalance logs. Moving this BZ to Verified.
