Gluster users - Dec 2017 - [Gluster-devel] Announcing Glusterfs release 3.12.2 (Long Term Maintenance)

Any idea when these packages will be in the CentOS mirrors? there is no
sign of them on download.gluster.org.

We're waiting for someone other than me to test the new packages at
least a little. Installing the packages and run something on top of a
Gluster volume is already sufficient, just describe a bit what was
tested. Once a confirmation is sent that it works for someone, we can
mark the packages for releasing to the mirrors.

Getting the (unsigned) RPMs is easy, run this on your test environment:

  # yum --enablrepo=centos-gluster312-test update glusterfs

This does not restart the brick processes so I/O is not affected with
the installation. Make sure to restart the processes (or just reboot)
and do whatever validation you deem sufficient.

Thanks,
Niels

Neil I  don;t know if this is adequate but I did run a simple smoke test
today on the 3.12.3-1 bits.   I installed the 3.12.3-1 but on 3 fresh
install Centos 7 VMs

created a 2G image  files and wrote a xfs files system on them on each
system

mount each under /export/brick1,  and created /export/birck1/test  on each
node.
probes the two other systems from one node (a).  abd created a replica 3
volume using the bricks at export/brick1/test on each node.

started the volume and mounted it under /mnt/gluster test on nodes a.

did some brief  tests using dd into the mount point on node a, all seemed
fine - no errors nothing unexpected.
