IT35357：卸载停止，消息CTGGA0309关于/ OPT / VSNAP-DATA中的空闲空间不足，尽管尺寸正确

错误描述

• The IBM Spectrum Protect Plus offload volume cache file size is
  incorrectly set to 6 GB instead of the expected 512 MB.
  Per cloud volume, there will be such a cache file :
  /opt/vsnap-data/offload<CloudVolumeID>/objectcache
  
  It can be
  checked as follows :
  [[email protected] ~]$ sudo find
  /opt/vsnap-data -name objectcache -exec du -h {} \;
  6.2G
  /opt/vsnap-data/offload<CloudVolumeID_1>/objectcache
  6.2G
  /opt/vsnap-data/offload<CloudVolumeID_2>/objectcache
  6.2G
  /opt/vsnap-data/offload<CloudVolumeID_3>/objectcache
  ...
  
  This causes an unexpected usage in the offload cache location of
  the
  vSnap host despite the sizing being correctly set according to
  the BluePrints (//www.lovechugsblog.com/support/pages/ibm-spectrum-p
  rotect-plus-blueprints) recommendations.
  
  When the available
  space is exhausted, the following messages will be seen
  in a failed offload job log :
  ERROR,<timestamp>,CTGGA0309, Copy
  failed for snapshot (ID: xxxx) from source [server:
  <SourcevSnapHostIP>, volume: <SourceVolume>, snapshot:
  <SourceSnapshot>] to target [server: <TargetvSnapHostIP>,
  volume: <TargetVolume>]. Error: Exception: Failed to create
  gateway device: Cloud temporary data location /opt/vsnap-data
  has yy GB free space which is less than the required
  25.00G

本地修复

• 1. Set the following preference on each vSnap:
  vsnap system
  pref set --name cloudRestoreCacheSize --value 536870912
  2.
  Delete the existing objectcache files while no jobs are
  running.
  The cache will be recreated at the smaller size during
  the next job run:
  sudo find /opt/vsnap-data -name objectcache
  -delete
  3. Once the fixing IBM Spectrum Protect vSnap version
  is applied, remove the option setting :
  vsnap system pref clear
  --name cloudRestoreCacheSize

问题结论

• An incorrect preference value was used while constructing the
  object cache during copy to cloud, resulting in unnecessarily
  large cache files. The problem has been resolved by using the
  correct preference value. Upon upgrading to the fixed version,
  the existing object cache files will initially remain at the
  same size but they will gradually be deleted and recreated with
  the new smaller size as and when cloud copy jobs run.
