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

    Protect Plus 10.1.7

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.
