如果使用网络组、则挂载NFS共享将失败、并且DNS反向查找将返回多个主机名
适用场景
- ONTAP
- NFS
问题描述
- 使用网络组时挂载NFS共享失败、并且由于返回多个主机名、反向查找失败
- MGWD日志包含反向查找错误：
0x837290200: 0: ERR: LIBCWRAPPER::utils: getHostAliasesForNetgrp:src/utils/utils.cc:102 VSID: 3. Reverse lookup for XX.XX.XXX.XX returned more than one hostname0x837290200: 0: ERR: LIBCWRAPPER::utils: getHostAliasesForNetgrp:src/utils/utils.cc:102 VSID: 3. Reverse lookup for XX.XX.XXX.XX returned more than one hostname- 即使
client does not belong to netgroup主机是成员、MGWD导出检查也会失败。
