Severity: 4-Minor


While restoring a UCS archive, you get an error similar to the following example: /var: Not enough free space 535162880 bytes required 326418432 bytes available /shared/my.ucs: Not enough free disk space to install! Operation aborted. /var/tmp/configsync.spec: Error installing package Config install aborted. Unexpected Error: UCS loading process failed. As part of restoring UCS archives, some files (for example, the contents of the filestore) are temporarily copied to the /var/tmp directory. The script that ensures enough free disk space is available for the UCS restore operation incorrectly reports the /var filesystem's free disk space for the /var/tmp directory. This is incorrect, as /var/tmp is a symlink to /shared/tmp, and so the free disk space of the /shared filesystem should be used instead.


The UCS installation fails even if /var/tmp has sufficient disk space.


-- Restoring a UCS file. -- The UCS file contains large items that are temporarily stored under the /var/tmp directory (for example, many EPSEC files, many large external data-groups, etc.). -- The /var filesystem has limited free disk space.



Fix Information

The UCS installation script now reports the correct free disk space for the /var/tmp directory, allowing UCS archive installations to complete.
