Chapter 2. Bug Fixes

This section documents important bugs that affected previous versions of Red Hat Hyperconverged Infrastructure for Virtualization that have been corrected in version 1.7.

BZ#1670722 - Changed device names after reboot break gluster brick mounts
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#1723730 - 512 byte emulation required for VDO
Virtual Disk Optimizer devices were previously required to use 512 byte emulation before 4KB block devices were fully supported. This emulation is no longer required and has been removed now that 4KB block device support is available.
BZ#1780290 - Non-operational host with sharding enabled
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.
