RHBA-2020:0508 - Bug Fix Advisory

Topic

A new release of Red Hat Hyperconverged Infrastructure (RHHI) for Virtualization that fixes several bugs and adds various enhancements is now available.

Description

Red Hat Hyperconverged Infrastructure (RHHI) for Virtualization integrates
Red Hat Virtualization and Red Hat Gluster Storage, allowing you to
consolidate deployment and management of compute and software-defined
storage resources.

This version upgrades Red Hat Virtualization packages to version 4.3.8
and Red Hat Gluster Storage packages to version 3.5. These updated
packages provide a number of bug fixes and enhancements.

This update fixes the following bugs:

• Gluster bricks were previously mounted using the device name.

This device name could change after a system reboot, which made
the brick unavailable. Bricks are now mounted using the UUID
instead of the device name, avoiding this issue. (BZ#1670722)

• When sharding was enabled and a file's path had been unlinked,

but its descriptor was still available, attempting to perform a
read or write operation against the file resulted in the host
becoming non-operational. File paths are now unlinked later,
avoiding this issue. (BZ#1780265)

• When sharding is enabled on a volume, a single file allocation

operation creates all shards in a single batch. If the number of
shards involved in an operation was greater than the number of
entries allowed in the lru-cache, the inode associated with the
file operation was freed while it was still in use. This led to
a crash in the mount process when deleting large files from
volumes with sharding enabled, which caused all virtual machines
that had mounted that storage to pause. This issue is no longer
observed in these updated packages. (BZ#1694604)

This update also provides the following enhancements:

• Full support for devices with a 4KB block size. (BZ#1721020)
• VDO volumes now use a block size of 4KB by default. Gluster

volumes should not be created across both new and old VDO volumes,
as Gluster volumes require bricks to share a common block size.
(BZ#1723730)

• Previously, volumes were created across all nodes. In deployments

larger than three nodes, you can now select which nodes you want
volumes to be deployed across. (BZ#1774851)

Red Hat recommends that all users of RHHI for Virtualization upgrade
to these updated packages, which fix these issues and provide these
enhancements.
