RHEA-2016:1250 - Product Enhancement Advisory

Topic

Updated gdeploy package that fixes several bugs and adds various
enhancements are now available for Red Hat Gluster Storage 3.1 update 3.

Description

gdeploy is a tool which automates the process of creating, formatting,
and mounting bricks. When setting up a fresh cluster, gdeploy could be the
preferred choice of cluster set up, as manually executing numerous commands
can be error prone. The advantages of using gdeploy includes automated
brick creation, flexibility in choosing the drives to configure (sd, vd,
etc.), and flexibility in naming the logical volumes (LV) and volume groups
(VG).

This advisory fixes the following bugs:

• Previously, if the sub-directory is not mentioned during volume creation, the volume would be created on the root of the mount point. Due to this, user might end up creating files on the root of the mount-point, which is not recommended. With this release, gdeploy reports an error and does not create the volume unless `force' is explicitly mentioned. [BZ#1261808]
• In case of failures gdeploy would stop at that point and the user had to manually undo the partially completed operations before restarting the program. This was a manual and cumbersome exercise, and user had to login to the machines to fix. With this release gdeploy now continues from where it left off and all the earlier completed steps are ignored. [BZ#1311084]
• Rebalance operation tries to start the gluster volume before doing the

actual rebalance. In most of the cases, volume is already in `Started'
state. If the volume is already started and the volume start command fails,
gdeploy considers that volume has started and does not start the rebalance
process. With this fix, gdeploy verifies the volume status and tries to start the volume only if it is stopped before initiating the rebalance. [BZ#1266874]

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
