2. Bug Fixes¶
pcompact operation is much slower for the containers on Virtuozzo Storage than for the ones stored locally. (PSBM-95772)
Processes could get stuck in copy_net_ns() forever. (PSBM-96057)
Storage: certain errors in CS caused by power failures were not handled properly. It was discovered that if a file located on Virtuozzo Storage cluster was reopened, the kernel could reuse its mappings without notifying MDS. As a result, if errors were then detected on a CS, for example, caused by power failures, the userspace components would be unable to handle them properly. (VSTOR-24004)
