linux log 出現 consider increasing the number of threads

nfsd status 可以看這兒，檢查當前 nfsd 線程數

• cat cat /proc/net/rpc/nfsd

rc 0 0 0

fh 0 0 0 0 0

io 0 0

th 8 0 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000

ra 32 0 0 0 0 0 0 0 0 0 0 0

net 0 0 0 0

rpc 0 0 0 0 0

proc2 18 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

proc3 22 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

proc4 2 0 0

proc4ops 59 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

一般正常的 centos based 的 nfsd 預設應該是 8個，如果 /var/log/messanger 提示 consider increasing the number of threads，可以考慮加大線程數量

• vim /etc/sysconfig/nfs

找到RPCNFSDCOUNT的部份，把值放大

- Number of nfs server processes to be started.

- The default is 8.
#RPCNFSDCOUNT=8

RPCNFSDCOUNT=16
