在数据包捕获中， NFS3ERR_NOSPC 可以看到：
 

NFS 266 V3 RENAME Call (Reply In 121), From DH: 0x73953be7/testfile123 To DH: 0x73953be7/.nfs000000010001329500000009 

NFS 162 V3 RENAME Reply (Call In 120) Error: NFS3ERR_NOSPC

 

Cause

文件正在使用中，导致写入 .nfs 文件，直到不再使用该文件。由于超过了配额，无法写入 .nfs 文件。这被认为是一个愚蠢的重命名，是客户端而不是服务器做的事情。

And fails because the quota is exceeded

Resolution

通常运行 lsof 在客户端上标识哪个进程打开了文件。但是，在至少一个实例中，客户端上的 CrowdStrike 创建了 .nfs 文件但被阻止 lsof 从将其显示为打开。临时禁用 CrowdStrike 会删除该文件。如果必须恢复 .nfs 文件出现在数据包捕获中，确认客户端进程正在使用该文件，这可防止在超过硬配额时将其删除。

[root@centos tmp]# lsof testfile123
COMMAND   PID USER   FD   TYPE DEVICE  SIZE/OFF       NODE NAME
tail    13992 root    3r   REG   0,43 104857600 4337893434 testfile123

Once the process that has the file in use is stopped the file can then be removed

[root@centos tmp]# rm -f testfile123
[root@centos tmp]#

Additional Information

什么是“愚蠢的重命名”？为什么这些 .nfsXXXXX 文件不断出现？
