【问题描述】：
我的系统是 Cent OS7，我安装了torque-6.1.0 配置./configure --prefix=/opt/pbs --with-debug --with-scp --disable-gcc-warnings
我的服务器名称是“node00”，我添加了一个名为“node01”的从节点
[root@node00 torque]# pbsnodes
node01
state = free
power_state = Running
np = 16
ntype = cluster
status = opsys=linux,uname=Linux node01 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64,nsessions=0,nusers=0,idletime=7057,totmem=98382176kb,availmem=97993700kb,physmem=32846184kb,ncpus=16,loadave=0.00,gres=,netload=286314300,state=free,varattr= ,cpuclock=Fixed,macaddr=0c:c4:7a:02:ba:98,version=6.1.0,rectime=1481028058,jobs=
mom_service_port = 15002
mom_manager_port = 15003
我提交了一份简单的工作echo "sleep 5" | qsub
然后它在qstat -f中返回了一条错误消息
queue_type = E
sched_hint = Unable to copy files back - please see the mother superior's
log for exact details.

于是我看了女上司的日志vi /var/spool/torque/mom_logs/20161206

node01 和 node00 似乎无法互相发送数据。这样对吗？我该如何解决这个问题？
【问题讨论】：
-
要检查的东西：确认服务器和计算是相同的版本。确认您没有运行额外的 pbs_mom 进程。在服务器和节点上禁用 ipchains 和 iptables。在 mom_priv/config 中增加 $loglevel，重启 pbs_mom，然后查看 mom 的 log 和 syslog。
-
你提到的检查清单做得正确。我安装了较低扭矩的版本，然后错误消息更像
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)。它看起来像 ssh 权限问题。但是我用./configure --with-rcp=/usr/bin/rcp安装了这个版本，那为什么我的扭矩还想用ssh呢？ .. -
无论如何.. 我生成了授权密钥，然后它运行良好。但是为什么
torque不使用rsh仍然让我感到困惑。谢谢！
