원인
- There is an issue with the code in NFSv4_ClientList::Clean().
- Upgrading to Cumulative Epack 5978.711.711_9699 or 9734 will upgrade eNAS version to 8.1.15.401 and introduce exposure if a filesystem is mounted with NFSv4.
해결
- Customers running eNAS version 8.1.15.401 (Released in Cumulative Epacks 5978.711.711_9699 and 9734) and have NFSv4 mounted filesystems the recommendation is to remount the filesystem with NFSv3.
- Customers running eNAS version 8.1.15.401 should submit an Epack request, requesting eNAS version 8.1.15.402.
