IT45821: ORPHAN DATA CAN FILL UP /OPT/VSNAP-DATA WHEN MULTIPLE COPY TO CLOUD FAILURES ARE SEEN

APAR status

• Closed as program error.

Error description

• The copy to cloud feature was made available in IBM Spectrum
  Protect Plus starting with version 10.1.3.
  When there are multiple copy to cloud failures, left over
  orphaned metadata can fill up the cloud cache directory
  /opt/vsnap-data.
  Once that directory reaches 100% occupancy, it prevents new
  offloads from starting.
  
  
  
  
  
  IBM Spectrum Protect Plus Versions Affected:
  IBM Spectrum Protect Plus 10.1.3 and later
  
  
  
  
  Additional Keywords: SPP, SPPlus, TS015182631, Storage Protect
  Plus, offload, cloud
  

Local fix

• 1. Ensure there is no active copy to cloud session with the
  vSnap command :
       vsnap cloud session show
  2. Manually delete any files with the keyword "tmp" in the file
  name in /opt/vsnap-data and subdirectories.

Problem conclusion

• In IBM Spectrum Protect Plus 10.1.3 and later, failed cloud
  offloads could leave behind temporary blockmap data, causing the
  /tmp directory of a vSnap to fill up (causing disk exhaustion).
  This issue has been corrected in IBM Spectrum Protect Plus
  10.1.16.2 and 10.1.17.
