在數據包捕獲中， 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

檔案正在使用中，這會導致寫入 .nfs 檔案，直到檔案不再使用為止。由於超過配額，因此無法寫入 .nfs 檔案。這被認為是一個愚蠢的重命名，是用戶端執行的操作，而不是伺服器執行的操作。

And fails because the quota is exceeded

Resolution

通常執行中 lsof 在用戶端上標識哪個進程打開了檔。但是，在至少一個實例中，用戶端上的 CrowdStrike 建立了 .nfs 檔案，但已阻止 lsof 從顯示為打開。暫時停用 CrowdStrike 後，可移除檔案。如果 .nfs 檔案會出現在封包擷取中，確認用戶端程序正在使用該檔案，這可防止在超過硬配額時將其移除。

[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

什麼是「愚蠢的重命名」？為什麼這些 .nfsXXXXX 檔案不斷出現？
