1. Overview

The cumulative Virtuozzo ReadyKernel patch was updated with stability fixes. The patch applies to the kernels 3.10.0-862.20.2.vz7.73.24 and 3.10.0-862.20.2.vz7.73.29 (Virtuozzo 7.0 Update 9 and Virtuozzo Infrastructure Platform 2.5) and 3.10.0-957.10.1.vz7.85.17 (Virtuozzo 7.0 Update 10).

2. Bug Fixes

  • I/O errors were reported after a successful replacement of the ploop images. (VSTOR-22272)

  • It was found that if a ploop image was revoked and then replaced using ‘ploop replace’, ‘abort’ flag was not cleared. As a result, subsequent I/O operations would fail. (VSTOR-22414)
