[Gluster-users] File deletion gets corrupted on cluster-resize.

[Kazuyoshi Tlacaelel]

Thanks for your feedback.

You can find the logs here. http://cl.ly/273p0T0E1r2X2C243M2s

gluster> volume info all 

Volume Name: gluster_replication
Type: Distributed-Replicate
Status: Started
Number of Bricks: 2 x 2 = 4
Transport-type: tcp
Bricks:
Brick1: 110.1.1.256:/ebs/gluster_2_volume_1
Brick2: 110.2.2.256:/ebs/gluster_1_volume_1
Brick3: 110.3.3.256:/ebs/gluster_2_volume_2
Brick4: 110.4.4.256:/ebs/gluster_1_volume_2


The error happens when you perform the resize (adding: gluster_2_volume_2 & gluster_1_volume_2)
and run the following command at the same time.

> cp -r rails /gluster/external_copy & cp -r /gluster/original /gluster/internal_copy & rm -rf /gluster/delete

They will be present in /usr/local/var/log/glusterfs for source installation (if you hace installed with some prefix, then logs will be present in <prefix_path>/var/log/glusterfs). If you have installed from rpm, then logs will be present in /var/log/glusterfs.
