NetBackup 8.1 / 3.1 CloudCatalyst EEB Bundle (Etrack 3958410)

HotFix Critical

Abstract

A hotfix is available for NetBackup 8.1 / 3.1 which resolves issues seen after an upgrade

Description

A hotfix is available for NetBackup 8.1 which resolves the following issues seen after an upgrade:

  • The cache eviction takes a long time. The delete request prevents the upload request.
  • Performance improvement for uploads to cloud
  • Certain error conditions could cause failed uploads to be reported as successful resulting in potential data loss.
  • A hang could occur after several hours or days as a result of a previous non-graceful service shutdown.
  • A fix to the Azure plugin is included - vxesp crashes leading to hung CC jobs.
  • The rocksdb library has been upgraded to the latest available version to prevent vxesfsd crashes.
  • The cache eviction logic fails on some CloudCatalyst servers installed on xfs or other filesystems.This results in a cache full scenario and jobs failing with write errors.
  • vxesfsd is crashing in rocksdb. Set FSDB block cache size or disable it.
  • vxesfsd crashes in del_file when deleting a file which had nlink set to 0 in FSDB.
  • vxesfsd is crashing in esfs_opendir() due to a null-pointer exception.
  • vxesfsd is crashing in boost libraries. Remove boost from vxesfsd.
  • Added more detailed logging for cache eviction.
  • Do not run cache eviction every 10 seconds if very little space is freed.
  • Do not use status 1 in image stat file because it is treated as success by MSDP.
  • Avoid crash from incorrect path in upload file list.
  • Do not use world-writable permissions on created directories.
  • Make sure that correct status is returned on failure for rmdir.
  • Do not write __EMPTYFILE__ into .bin/.bhd files

 

Version 11:
