适用场景

ONTAP 9

问题描述

  • CIFS访问失败和/或NFS客户端访问挂起。
    • 数据包跟踪显示了正在使用应答的NFS打开请求 NFS4ERR_DELAY

NFS V4 Call (Reply In 18) OPEN DH: 0xfbfc02ab/x_file.bin
NFS  V4 Reply (Call In 11) OPEN Status: NFS4ERR_DELAY

  • 正在使用回答CIFS创建请求 STATUS_INSUFFICIENT_RESOURCES

 

SMB2   Create Request File: x123.p123.local\share1\archive.ppt
SMB2   Create Response, Error: STATUS_INSUFFICIENT_RESOURCES

  • EMS日志中将显示类似于以下内容的消息:

ERROR lmgr.owners.limit.hit: The number of owner objects 413800 has reached the limit 413800 for the pool <nodename>. The current number/limit of other lock manager objects are: files 410381/413800 hosts 16/50000, locks 416661/827600.

  • 此时将报告类似于以下内容的Spinhi-stats err [SPINNP_ERR_NOLOCK = 77,           // No locks available] :

Open: count=106261335 hipri=0 errs=4698192 elapsed: max=5803357.24 avg=831.40
    spinhi cpu: max=2965.05 avg=21.47
    wafl cpu: max=5803328.35 avg=801.38 restarts=13314078
    errs: 77[320325]
