NetBackup 8.1.1 / 3.1.1 CloudCatalyst EEB Bundle (Etrack 3956754)

HotFix Critical


A hotfix is available for NetBackup 8.1.1 / 3.1.1 which resolves issues seen after an upgrade


Added A hotfix is available for NetBackup 8.1.1 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
  • Download size is not the same value as fsdb. Disable download size check in case the
  • size in fsdb is incorrect.
  • Cannot remove certain directories. Change rmdir logic of checking directory is empty.
  • This change makes sure that directory with garbage data is able to be deleted.
  • vxesfsd crashing. Set max open file to limit RocksDB memory allocation. The allocated
  • RSS memory will never be larger than 1GB.


Added to Version 13:

  • Implement write pause instead of fail when the cache hits the high watermark (the cache is full). Container write will be paused during cache eviction time.
  • ET 3990062:
  • Improve performance of opendir/readdir (remove support for optional d_type on readdir since MSDP does not use it)
  • Cache eviction improvements
  • Skip bhd files and recently modified files during cache eviction
  • If unable to reclaim enough space, consider them for eviction the next time
  • Check disk usage no more than once every 10 seconds
  • Cache sys_ino for /data and /databases for performance
  • Remove unnecessary lock for esfs_opendir for MSDP performance
  • Improve parse_upload_filelist performance
  • Cache sys_ino values while parsing the filelist to reduce stress on fsdb
  • Assume root directory is ESFS_ROOT_INO instead of querying fsdb on every esfs_lookup call
  • Fix error status for readonly mode for upload msdp system files
  • Avoid possible duplicate ino in case of fsdb error
  • ET 3990446: Propogate error properly on failed cloud delete request
