The pre-upgrade check detects the numbers of remaining inodes in the /sfdata/log and /sfdata/var directories. If the numbers are smaller than the thresholds (25,000 for /sfdata/log and 16,000 for /sfdata/var), the error (code: 0005-0007) will be triggered.

Temporary files will be created in the /sfdata/log and /sfdata/var directories during the upgrade. This consumes a certain number of inodes. If there are insufficient available inodes, the upgrade will fail because these temporary files cannot be created.

If the error (code: 0005-0007) appears after the pre-upgrade check, contact the service provider or Sangfor technical support.
