Unexpected exception during upgrade to 7.1.x.x

Troubleshooting


Problem

Upgrading a production AIX Cluster from 6.3.x.x to 7.1.x.x. the active node was upgraded without issue but the passive node failed with not enough space in the filesystem.

Symptom

<message>Error backing up files from /opt/IBM/IBMIMShared/native/com.tivoli.dsm.server.db2.aix.ppc64_10.5.301.86.zip
java.io.IOException: There is not enough space in the file system.</message>

Cause

The installer uses /var/ibm/InstallationManager/adapters/native to save the backup files. It will attempt to save the file(s) in /var

Diagnosing The Problem

Per the Tivoli Storage Manager 7.1 server installation guide the following minimum values for disk space:



    512 MB for the /var directory <-------- HERE
    5 GB for the installation directory
    2 GB for the /tmp directory
    300 MB for the /usr directory
    2 GB in the home directory
    Tip: Expect to use more space for problem determination.
    2 GB for the shared resources area

When looking at the df -k you see all filesystems meet the minimum requirements with both free space and total space

    > df -k
    Filesystem    1024-blocks      Free %Used    Iused %Iused Mounted on
    /dev/hd4          1572864   1099476   31%    14268     6% /    
    /dev/hd2         10223616   2463040   76%    88238    14% /usr  
    /dev/hd9var       2621440   1015916   62%    13562     6% /var <--- HERE
    /dev/hd3          7602176   4278524   44%     2173     1% /tmp  
    /dev/hd1          2097152    297588   86%     2909     5% /home
    /proc                   -         -    -         -     -  /proc
    /dev/hd10opt     16777216   8595404   49%   102569     6% /opt
    ....(snipped for brevity)

The file that can not be backed up is just over 1GB:

    ls -ltr /opt/IBM/IBMIMShared/native/com.tivoli.dsm.server.db2.aix.ppc64_10.5.301*

    -rw-r--r--    1 root     system   1075023171 Nov 16 13:09

Per the df -k output /var has less than 1GB free space and is the cause of the failure though the installation guide indicates /var has sufficient space.

Resolving The Problem

Add ample space to /var in case additional files need to be backed up. Once the upgrade has completed the space can be reduced as needed.
