Hi All, Here we have below steps to reproduce the issue
Reproduction steps: root@128:~# gluster volume create brick 128.224.95.140:/tmp/brick force ----- create the gluster volume volume create: brick: success: please start the volume to access data root@128:~# gluster volume set brick nfs.disable true volume set: success root@128:~# gluster volume start brick volume start: brick: success root@128:~# gluster volume info Volume Name: brick Type: Distribute Volume ID: a59b479a-2b21-426d-962a-79d6d294fee3 Status: Started Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: 128.224.95.140:/tmp/brick Options Reconfigured: nfs.disable: true performance.readdir-ahead: on root@128:~# gluster volume status Status of volume: brick Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------ ------------------ Brick 128.224.95.140:/tmp/brick 49155 0 Y 768 Task Status of Volume brick ------------------------------------------------------------ ------------------ There are no active volume tasks root@128:~# mount -t glusterfs 128.224.95.140:/brick gluster/ root@128:~# cd gluster/ root@128:~/gluster# du -sh 0 . root@128:~/gluster# mkdir -p test/ root@128:~/gluster# cp ~/tmp.file gluster/ root@128:~/gluster# cp tmp.file test root@128:~/gluster# cd /tmp/brick root@128:/tmp/brick# du -sh * 768K test 768K tmp.file root@128:/tmp/brick# rm -rf test --------- delete the test directory and data in the server side, not reasonable root@128:/tmp/brick# ls tmp.file root@128:/tmp/brick# du -sh * 768K tmp.file *root@128:/tmp/brick# du -sh (brick dir)* *1.6M .* root@128:/tmp/brick# cd .glusterfs/ root@128:/tmp/brick/.glusterfs# du -sh * 0 00 0 2a 0 bb 768K c8 0 c9 0 changelogs 768K d0 4.0K health_check 0 indices 0 landfill *root@128:/tmp/brick/.glusterfs# du -sh (.glusterfs dir)* *1.6M .* root@128:/tmp/brick# cd ~/gluster root@128:~/gluster# ls tmp.file *root@128:~/gluster# du -sh * (Mount dir)* *768K tmp.file* In the reproduce steps, we delete the test directory in the server side, not in the client side. I think this delete operation is not reasonable. Please ask the customer to check whether they do this unreasonable operation. *It seems while deleting the data from BRICK, metadata will not deleted from .glusterfs directory.* *I don't know whether it is a bug of limitations, please let us know about this?* Regards, Abhishek On Thu, Apr 13, 2017 at 2:29 PM, Pranith Kumar Karampuri < pkara...@redhat.com> wrote: > > > On Thu, Apr 13, 2017 at 12:19 PM, ABHISHEK PALIWAL < > abhishpali...@gmail.com> wrote: > >> yes it is ext4. but what is the impact of this. >> > > Did you have a lot of data before and you deleted all that data? ext4 if I > remember correctly doesn't decrease size of directory once it expands it. > So in ext4 inside a directory if you create lots and lots of files and > delete them all, the directory size would increase at the time of creation > but won't decrease after deletion.
