RHBA-2020:0288 - Bug Fix Advisory

Topic

Updated glusterfs packages that fix several bugs are now available for Red
Hat Gluster Storage 3.5 Batch 1 Update on Red Hat Enterprise Linux 7.

Description

Red Hat Gluster Storage is software only scale-out storage solution that
provides flexible and affordable unstructured data storage. It unifies data
storage and infrastructure, increases performance, and improves
availability and manageability to meet enterprise-level storage challenges.

This advisory fixes the following bugs:

• Special handling is sometimes required to ensure I/O on clients with older versions works correctly during an in-service upgrade. Servers with dispersed volumes do not do this handling for Red Hat Gluster Storage 3.3.1 clients when upgrading to version 3.5. With this update, if you are using dispersed volumes and have clients on Red Hat Gluster Storage 3.3.1, perform an offline upgrade when moving server and client to version 3.5. (BZ#1766640)
• With this update removal of bricks will be aborted with a proper warning message if re-balance process has failed or there are some skipped files. However, users can still remove the brick by using the 'force' option. (BZ#1344758)
• Previously, after rebalance was completed, if the glusterd was rebooted gluster volume rebalance status was displaying the wrong size. Now, rebalance status displays the size correctly. (BZ#1761486)
• Performance translators, 'io-cache' and 'read-ahead' were not adding any performance improvement. The 'read-ahead' is redundant due to kernel 'read-ahead' and 'io-cache' was degrading the performance for workloads that don’t involve re-read. As the VFS layer already has both these functionalities, the two translators have been turned off by default for native fuse mounts. Due to this, there is improved performance for the sequential read. (BZ#1788656)
• The 'gluster volume heal <volname> info' always does a DNS name resolution. When DNS address resolution takes 30 seconds to fail, the command fails as it crosses the time out value set for gluster AFR volumes. With this fix, 'gluster volume heal <volname> info' command does not resolve the erroneous address and it works correctly even when DNS-server configuration has issues. (BZ#1758923)

All users of glusterfs are advised to upgrade to these updated packages,
which provides numerous bug fixes.
