Gluster users - Sep 2011 - File deletion gets corrupted on cluster-resize.

Two master-servers, one client.

Client mount point is: /gluster
replica is: 2

A testing-directory (git repo) with data exists, and is used for testing the
following.

STEP 1
First, we copy the testing-directory to /gluster/original
Then, we copy the testing-directory to /gluster/delete
STEP 2
Copy /gluster/original to /gluster/internal_copy
Copy testing-directory to /gluster/external_copy
Delete /gluster/delete
cp -r rails /gluster/external_copy & cp -r /gluster/original
/gluster/internal_copy & rm -rf /gluster/delete

While executing the command above, only the delete part returns an error:

rm: FATAL: directory `/gluster/delete/activerecord/test/migrations' changed
dev/ino

Note: that this corruption only happens while the a new-brick is added to the
system.
and that that is executed at the same time as STEP 2.
Which purpose is to replicate a live production environment.

RESULT

I've confirmed that the files within the following directories are
consistent:
/gluster/original
/gluster/external_copy
/gluster/internal_copy
But delete doesn't get deleted, its actually just
"partially-deleted".
then, when everything is done, and a delete is performed manually the directory
gets deleted just fine.

Hi Kazuyoshi Tlacaelel,

Can you please provide the glusterfs client, glusterfs server and glusterd
logs? 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.

Also can you provide the output of gluster volume info <volname>?

Thanks

Regards,
Raghavendra Bhat
