RHBA-2019:2557 - gluster-ansible bug fix and enhancement update

Synopsis

gluster-ansible bug fix and enhancement update

Type/Severity

Bug Fix Advisory None

Topic

Updated gluster-ansible packages that fix several bugs and add one enhancement are now available.

Description

The gluster-ansible packages provide a number of ansible roles for deploying and managing GlusterFS clusters.

This update provides the following bug fixes:

  • During cleanup of a failed deployment, not all files were removed. This meant that when users tried to redeploy, they saw an option to use an existing deployment configuration even though any existing configuration should have been removed. All files are now correctly removed during cleanup, and the 'Use existing deployment' option is no longer visible after cleanup. (BZ#1654124)

  • During deployment, host names were previously verified using the dig command. This command did not validate host names specified in the /etc/hosts file, so deployment failed. Host names are now validated using the getent command, which is able to validate host names set in the /etc/hosts file. (BZ#1692662)

  • Previously, the sysfs pseudo file system was used to verify the logical block size of a disk being used as a brick. However, this failed when partitions of a disk were used instead of an entire disk, because the /sys/block//queue/logical_block_size file being checked relates only to whole disks. The output of the blockdev command is now used to verify logical block size instead, and deployment succeeds when either whole disks or partitions are used to create bricks. (BZ#1713816)

  • Previously the gluster_peer module did not detach peers correctly during cleanup, so peers remained connected and the cleanup playbook failed as a result. The shell module is now used to collect the list of peers and detach them correctly so that cleanup succeeds. (BZ#1692786)

It also includes the following enhancement:

  • Thinly provisioned bricks are now supported on top of Virtual Disk Optimization (VDO) devices. (BZ#1690606)

All users of Red Hat Gluster Storage are advised to upgrade to this upgraded version of gluster-ansible.
